Chevy Engine Code Information

The important thing is the serial number that starts with UP in this scenario most likely. Having an earlier model SNES isn't necessarily the best if you're someone who prefers the 1-Chip SNES's like myself. Plus the earlier models are more likely to yellow. I sadly have a rough top NES. This means that the sides are all smooth but the top is rough. Although they appear similar, the smooth top does shine up nicer and is rarer. These models have low serial numbers and the customer service sticker lists a phone number for “Inside Washington State”. Little Samson is an action platformer released for the NES back in 1992. Like many NES games released after the SNES launch, its sales were limited. Many fans were already investing in the latest Nintendo console, leaving Little Samson behind. Unboxed cartridges of this title go for as much as $1,000. Mint-in-box editions are well.

General Decoding Information
This topic can be somewhat confusing, especially with the amount of information available and the interpretation of it.The primary pieces of information you'll decode are the Engine Code and Partial VIN. You can decode the casting number. And you can check dates.The engine code and partial vin # will accurately nail down whatever the thing is rather quickly, and the other information will fall into line with that.If you already know what you're doing, Chevy Engine Codes are listed down below.

Which serial numbers are on the most valuable NES? - Quora

Let's decode something real quick like, you can read the details further down below:

Here's an engine. I can see the partial VIN (13N132794) and the engine code (V0112CLJ).
Quickly from the partial vin I know this is a Chevy (1) 1973 model year (3) built in Norwood Ohio (N).
132794 is the unique vehicle serial number (to match against vehicle VIN).
I know Norwood built Camaros - among other things. So I'm dealing with something from a 1973 Camaro.
Now to the engine code.
V0112 (flint, january 12th)
CLJ in 1973 is a 245 horsepower 350 used in a Z28 Camaro mated to a manual transmission.
Knowing this, I can conclude the original vehicles VIN is or was 1Q87T3N132794.
If that happens to be the vehicle this engine is currently sitting in they 'match'.
I'm Done.I can GUESS the casting # is 3970010 and check casting dates, etc... but using these 2 things, I already know EXACTLY what this was.

Here's another:
10S437638 & V0312CTG.
1970... S... St. Louis (built Vettes & Impalas). 4xxx is the Corvette Range. Yikes.
CTG - in 1970.... RPO ZQ3, 300hp 350 in a Corvette.
... and the Casting # is.... 3970010.

My point here I guess is... trying to decode '3970010' is almost pointless. It's a 350.If you're trying to buy a 350 and you see this thing laying on the ground, then there it is. But if you want to know EXACTLY what the thing is - you need more than the casting #. Once you identify something - like the above vette block, then you can conclude whatother pieces and parts should have been on it, and check those casting #'s. And/or - you can check dates to make sure everything came together when original.

ONE NOTE: Casting #'s will trump the code on a descrepancy. Take the above CLJ example. In 1987 CLJ is a 305 L69 in a monte carlo, or in 1971 it's a 400 from amonte carlo. So when the arguement over 305, 350 or 400 comes up... now you look at the casting #. 3970010.... bang, it's a 350. That eliminates the 400 and 305 possibilities.

As you can see - codes are reused and/or they span years. This is why I looked at the VIN code 1st. 1973 - eliminates every other possiblity. Everything else lines upand there's no confusion.

Engine Code Stamping Numbers
All engines are stamped with an engine ID code, consisting of assembly plant code, productiondate and suffix code. The location of this code depends on the type of engine, typically as follows:
Small Block Chevy: Machined pad in front of the passenger side cylinder head. Often hidden by the alterator.
Big Block Chevy: Machined pad in front of the passenger side cylinder head or above timing chain cover.
Six Cylinder: Passenger side of the block behind the distributor.
The prefix portion of the ID code tells you the engine assembly plant code, and the engine's assemblydate (for example, 0701 = July 1st....no year is indicated). The suffix portion tells you the original application, vehicle model, engine RPO/ transmission / horsepower, etc... (for example, CTY = 1970 396 Camaro, 375 hp, 11.0:1, TH400).

The engine assembly date must precede the car build date (often by a few days), otherwise something is amiss. Some engine machining operations (decking) will obliterate the engine ID.

Engine ID Code Example: V0101CLJ - (V = Plant, 01 = Month, 01 = Day, CLJ = Engine Suffix Code)
Another example: T0830CTY - (T = Tonawanda, 08 = August, 30 = 30th day, CTY = 1970 396 Camaro, 375 hp, 11.0:1, TH400)

VIN Code Format
The vin code format is stamped onto most engines. The format consists of divisional identificationnumber, model year, assembly plant designation and vehicle serial or sequence number.
In 68-69 model cars, the serial (VIN) number of the car the engine was installed in is stampednext to, or under the engine code ID.
Starting in 1970, the serial number is stamped either above the oil filter, somewhere on the blockpad (in front of the cylinder head), or on the transmission flange somewhere. Chevrolet issuedtechnical service bulletins to indicate which engines were to recieve a vin stamp, so who knows whatcould have happend (or not happened).

VIN code format Example: 13N100001
(1 = Chevrolet, 3 = 1973, N = Norwood, 100001 = Production sequence of vehicle VIN)

For a list of assembly plants, clickhere.


Suffix Portion of Chevy Engine Code

Suffix codes are either alphabetical or alphanumeric. Select the portion of the alphabet for your code. For example, select 'DTR-HQ' if you'd like to find code DZ. In some cases suffix codes are reused twice or more over time, in this event check the partial VIN code or block casting date code and then see what year the block was made to pin down what application your block was originally used in. This list of codes is a summarization, it is not complete nor all inclusive.

Small Block Engine Suffix Code Menu
3N - CDR CE - CMJ CMK - CUD CUF - DTM DTR - HQ
HR - TBS TBT - TJS TJT - TXB TXC - UTT UTU - ZY
Big Block Engine Suffix Code Menu
0FC - 9XZ AAA - CTB CTH - IJ IK - MZ Q - YZ

Note: CODE CExxxx (counter or crate engine) was used from 1968 to current year. It represents any CID and is used to indicate this particular engine was replaced under Warranty. It is a direct replacement for the original equipment. It doesn't indicate what the original equipment was.

Nes Serial Number Guide

VF292800 - is an example of a over the counter crate engine. '2800' is the last 4 digitsof the GM part # for the crate engine assembly. The final digit could be a year code.
Another example: A Targetmaster engine (p/n 14009800) built in 1985 could have a code stampedas follows:
A0198005 (A = january, 01, 9800 = pn, 5 = 1985).

Here's something secret I've been working on since 2005.

'Numbers Matching'
This is my opinion, and the generally accepted norm:
When people say 'It's numbers matching' - what they mean is the engine (or other component, i.e the transmission) can be MATCHED to the vehicle it was originally used in. This match is done via the PARTIAL VIN stamp on the component. The partial VIN will match the vehicles VIN. If it does - it's 'numbers matching',otherwise - it's not. done. end of story.
Some folks use these terms loosely, or will say 'numbers correct' or something to that effect. But numbers correct is not numbers matching. Again, it either matchesor it doesn't. If it doesn't match - is it correct?
Numbers matching is important when you're trying to decode a Z28 or Super Sport where the VIN won't identify the vehicle as such. You need to decode the engineand see if it matches the vehicle, and if the code signifies Z28 or SS equipment.
Lastly, in extreme cases, you'll want to verify the numbers stamped onto the component were the ones stamped into it originally and aren't restamped.
The point of this article is to help you figure out how to decode stuff.

What good is knowing the transmission? MT (or Manual transmission) IMPLIES - the boss (or the pivot itself) for the clutch Z-bar is present and threaded and the crankshaft can accomodate a pilot bearing. Good news is 99.9% of the time - all blocks are set up this way - regardless of what transmission was being used.

Hey man - is this a 4 bolt main?
I have no idea.... drilling the holes is a machining operation. It can be done on any 3970010 (or other) block. 99% of the time, the casting # won't indicate anything.HOWEVER - the engine code MAY HINT at this fact. Take a truck 350. If it codes out as a 1/2 ton application - we can bet money it's only a 2 bolt. but if it's a 3/4 or 1ton application, or some high powered application, you can ASSUME it might just be a 4 bolt main. Both of the above 350 examples are 4 bolt mains due to the application.The only guarantee is to take off the pan and look.

What's this A/F/X stuff?
This is the GM body designation. All these are identified here.Quickly, A = Chevelle, F = Camaro, X = Nova. If you're looking at the engine code - this is already known. If you're looking at the casting # information and it mentions3970010 'A/F/X/Y/B'.... basically this means 'it's used in everything', whereas if it simply states 'Y'... this means corvette.

Miracle Piano Guide - NES Cable - Foot Switch Mod
UPDATE - Added PC Cable Instructions in the 2nd Reply
Serial
The Miracle Piano came out in 1990 and can be hooked up to the NES, SNES, Genesis and computers to assist in learning how to play the piano. A custom serial cable for each console or computer communicates between the Piano and Console or PC to detect piano key presses and play back songs. This is an obscure Piano Keyboard that sometimes might be found online at a high price or a Rare chance discovery at a Thrift Store or Swap Meet. Surprisingly, the NES cart is more common then the piano keyboard, it can be found inexpensively online.
The Miracle Piano is no longer manufactured and can only be bought used. Sometimes the piano is missing the power supply, most of the time the Sustain Foot Pedal and proprietary serial communication cable is missing. In this Guide I will show how to replace the missing parts and build a custom Communication Serial Cable. I will focus on the NES, other systems can be built following the same procedure. At the end of the OP are references for other systems.
First a little background information on the Miracle Piano.
weltenschule wrote:http://weltenschule.de/TableHooters/Min ... Piano.html
The initial retail price in 1990 was about $500. Beside for PC (DOS or Windows 3.11) also software versions for Amiga and even for the Nintendo NES and Sega Megadrive Genesis game consoles were released. (Despite the game consoles this is not just a toy keyboard but has a far higher sound quality than e.g. My Music Center.) The hardware of this instrument was manufactured by Antex and the software by The Software Toolworks.
Miracle Piano Main Features
- 49 velocity sensitive fullsize keys (non- weighted)
- 2 built-in speakers (stereo, but rather thin and hollow sounding)
- polyphony 16 notes (only 8 notes with stereo preset sounds)
- 128 preset sounds (including 3 drum kits and 2 effect kits)
- all functions selected through only 8 buttons
- volume +/- buttons (10 steps) those also select other functions
- 6 function buttons {1= 'piano / melody 1', 2= 'vibraphone/ bass', 3= 'harpsichord/ melody 2', 4= 'elect piano/ percussion', 5= 'organ/ accompany', 6= 'synthesizer /select'} with each a green indicator LED
- 9 default key split modes {classical, rock, jazz, blues, rap, latin, country, cathedral, new age} those assign each a set of 6 OBS preset sounds to the 6 buttons
- 'library select' mode to select preset sounds by number (function button 6= sound '0', 1= 'step up', 2= 'step down', 3= '10 steps up', 4= '10 steps down')
- 10 step green LED indicator bar (for mode and volume)
- wavetable sound generator: all sounds based on medium and high resolution samples with partly audible zipper noise.
- no battery compartment
- jacks for AC- adapter, headphones, line out, foot pedal, MIDI in/ out and special serial port

Here are pics of a new Miracle Piano in a box, you can see the Foam Foot Pedal and NES cable:

Extra Connections
Here is what makes the Miracle Piano unique. The back has connections for Stereo RCA Audio out, Headphone Jack, Foot Pedal, Power Input, Midi In and Out and a proprietary 25 pin Serial connection. The Midi connections are standard and can be used with a PC or Mac to control the Piano. Play sounds, beats and songs controlled by the computer!
Power Supply
Any Power Supply that has AC 12 volt 1 Amp/1000 Milliamps output will do. The voltage must be 12 volt and the amperage can be higher but not lower. The AC voltage is uncommon, DC is the normal output on most power supplies.
Piano Education wrote:http://pianoeducation.org/pnompfaq.html
The OEM power supply for the Miracle is a 12 volt AC transformer, rated to deliver 1 amp. Since the current used is AC, there is no 'polarity' to concern one's self with. Any power supply that can supply AC at this voltage and amperage and has a compatible connector for the keyboard will work. One of our visitors says that she has successfully tested the Radio Shack 9-13VAC/800mA AC-to-AC Adapter for AT&T Answering Machines, Catalog #: 273-1631, $15.99 list, with her Miracle system. Although this adaptor is rated for 0.8 amps, rather than 1 amp, it has been discontinued by Radio Shack. Just about any adjustable voltage AC-to-AC adapter rated for around 1 amp will work, so long as you set the adjustable voltage to 12 V, on any AC transformer you might use with the Miracle.

Foot Pedal
The Foot Pedal connection allows a sustain feature in the Miracle Piano. The two prongs are very close to the power switch. Even if a sustain pedal is not added, a good idea to obtain a connector to prevent accidental shorting. The connector can be found at any electronics retailer such as Radio Shack or Frys. The square hole in the back of the piano is small. I had to file down the sides of a connector as well as opening up the hole a little in the back of the piano.
As for the Foot Pedal, any digital switch can be used that shorts the two prongs. Be sure it is not analog such as a game driving controller gas pedal. Switches can be found at music stores or a sewing machine foot switch or one can be built.
I already have a higher quality foot pedal at home, better then the original foam version. Anyone remember the Court Tape Recorder Foot Switch I bought a almost a year ago? I was going to make a Track and Field style controller out of it by gutting a PC keyboard encoder. Never did since it would have been for only a few games.
The pedal is perfect for the piano, but I had a concern. I'm almost positive the original Foot switch would just short the two prongs, but what if there is a resistor? Downloading the manual and schematics did not help, it took a brave YouTube poster to convince me. PAPERCLIPS?!
Any switch that completes the connections of the two pins works just fine.
Okay the Court Data Recorder Foot Switch works, an easy cut the end and solder in the right plug from my local electrician store. I spliced in both limit switches so either foot pedal produces the sustain feature.
Custom Serial Cable
The Miracle Piano has a 25 pin Serial Port, strangely it is upside down compared to a normal position of connector with more pins on top. The upside down connection is an important point to identify which pins will be used for the custom cable. I knew the NES can be hooked up, a search of the specialized cable shows a little on the pricey side. I have plenty of spare NES controllers to rob the cable with the game console Plug. The rest of the parts can be found at the local Electrical Supply retailer.
1. NES Controller - For the cable assembly
2. 25 Pin Serial Male Connector - Exposed Pins
3. 25 Pin Serial Connector Housing - Plastic or Metal
4. Electrical Tape - Black matches the cable
5. Heat Shrink - Various sizes
6. Lighter - Barbecue Lighter works well
7. Solder and Soldering Iron
8. Zip Tie - If no lock screw in housing
9. MultiMeter - If 3rd party controller, 1st party described below

The serial connector can be the type that has preinstalled pins or the pins can be bought separately. Preinstalled pins are harder to solder, but since there are only four wires I went this route. The plastic screw in the bag anchors the cable so a Zip Tie is not needed.

The NES controller plug and cable will be used with the 25 pin serial connector. Either desolder the wires or just cut the cable at the NES controller end. Do not toss the vintage NES controller, it might come in handy for parts or a future mod.
CRTGAMER wrote:I kept the NES controller, it can be used later for a custom controller. The NES controller buttons can easily be jumped to an Arcade Digital stick and buttons to compliment the stick with NES controller style game play. I am already envisioning a nine pin connector add on to my Wii Tatsunko Capcom Arcade Controller, but that will be a Guide later on.
EDIT UPDATE
The NES controller mod is done, a direct plug in to a Wii Remote.

Strip away about two inches of the insulation from the NES controller cable to expose the inner five wires, then strip a little off each wire. If a 3rd party controller is cannibalized, the wire colors might be different. To be sure of the connections, a good idea to test each wire with a MultiMeter to verify the pin locations.
Looking towards the NES console as if connected, the pins are laid out with four on the left and three on the right. The NES connector pins for a 1st party Nintendo controller read starting from the TOP LEFT, note the top right has a larger number.

The serial connector housing is designed for a twenty five wire lead, so the NES five wire cable has to be made thicker. Make sure this is done before soldering any wires. Electrical tape can be used, but heat shrink offers a cleaner look.
CRTGAMER wrote:Place Heat Shrink in the cable before any soldering is done. If there is no lock screw in the connector housing, a zip tie wrapped around the wire, will prevent the wires from being pulled from the soldered assembly.

Place an initial small wrap of Electrical Tape to make the cable thicker. Follow thru by covering with Heat Shrink. Use the Lighter to reduce the size of the Heat Shrink. Add a layer and heat each layer one at a time, use a larger sized Heat Shrink if needed. When completed the insulation should be the same thickness as the connector housing cable hole.
Solder the wires
Check and double check the pin locations. There are thirteen pins on top and twelve on the bottom. Online searches have instructions, but are not clear due to the serial pin connected upside down. Refer to the pic below for the exact locations, follow the pin numbers embossed on the connector plastic insulator.

The instructions are vague as to the view direction. All the pin connections online described were looking towards the NES console, even the Miracle Piano connector. The pic below has the the correct wire soldered locations, see the charts above to match the NES controller plug end.

Be careful, the thin cable wires can easliy break off from the solder connections. Glue can be used to reinforce the area but not needed if the cable is anchored. Install the wire assemby in the 25 pin housing, then tighten the two halves of the housing shell together. Push the cable in slightly to give a little slack then tighten the cable anchor. If a Zip Tie is used it should be placed inside the housing as to prevent any soldered wire separation if the cable is pulled. The piano does not have threads for the anchors at its 25 pin port so leave the connector cable connection lock screws off.

The Miracle Piano senses how hard the keys are struck, press softly for quiet passages, bang on the keys for a loud repertoire. The Sustain Foot pedal is a nice bonus feature which adds depth to a song. Even though the game software is from 1990, it actually has good sounds since the piano is providing the music. Discover hidden animal sounds built in the Miracle Piano and test every Piano key tone by tapping the direction keys. During the lessons, the NES cart can detect which piano key is pressed and give a visual cue on the TV. It also has games that can be interacted from the Miracle Piano. The songs included in the lessons start out as simple single key input all the way to two handed chorded functions. I will never become as good as Beethoven, but never know what hidden talent I might possess. I am utter crap when it comes to Karoke, maybe fare better using the fingers instead of my voice. I can always let the NES cart play the songs.
