TECH: Chevy Engine Numbers

Please help. Im new here and I purchased a 1952 chevy 3100 which has a later model inline 6. I got the engine code and it is "392968" which isn't listed. There is a 3921968. Is my engine missing the 1. Also behind the distributor is CON F 13 9. So is it a june 13 1969. Finally is it a 230ci or 250ci. PLEASE HELP. thanks

 

That would be a casting # which normally will not tell exactly what engine you have. Look for the STAMPED in #s on the flat area by the dist.,those will tell you 230-250.

 

Thanks Squirrel I thought that info. was gone forever.

 

Its says 29f 3710 sound rite?

 

Sorry 29f 2710

 

I was wondering if you can help identify my chevy inline 6. Here is what is on the block Con 2 E21 3 3789925. serial tag# F0427LB and the heads# 3836850. I was told the engine was a 235.

 

261 by the numbers. PM answered.

 

I have code T0726TCH. Could u help id what engine it is?

 

Tonawanda engine plant, July 26, Truck, don't know what the CH is.

 

TCH is the code for a 1973 truck 307.

The T at the beginning of the code means Tonawanda. The T after the numbers means Truck. Starting ni 1970, they went to 3 letter codes, and the Cars started with C, trucks with T.

 

My 283 casting number is clearly 3896964 which is a 1967 year, but where the vin would be it says VOI24 WA, so that is Flint, perhaps January 24, and WA is a 2 bbl 1965 C-10 to 30. That is the connundrum, the same source has it as a 67 and a 65. There is no vin so I gather this is a replacement engine.

 

There were no vins on 1960s engines, except for possibly corvettes.

There should be a casting date on the back of the block, on the other side.

WA code was used on 1967 truck 283 engines. I have the chevy truck parts book with the listings.

 

J66, and a tiny little three just at the china rail by its little lonesome. I don't believe it means a thing but thought it was funny that a random number should be there.

 

J 6 6 is Oct 6 1966, a little early for a January 24 assembly date...but who knows...

 

Please, can someone help me with this code?
My car is -73 Corvette, with engine assembly code :V0420TAP

Does that "T" after numbers mean, that it's orginally motor from truck not a car?

 

So the engine in my 1957 Cameo reads "CE 86144 5" . From reading this post it is a counter exchange engine? The vin denotes my truck as a v8 truck and the engine suffix for a 1957 265 with HD clutch is CE? My hopes were it was the original engine, but they are fading.

doesn't sound like the original engine. You could also check the casting date at the top rear of the block, see when it was made.

 

squirrel- I can't tell you how much I appreciate the knowledge you're sharing, and I did as much of my own research as I could before posting a request for help. I have a 327sbc that was in the 38 Ford truck shown on my page. It looks like someone tried to rod this truck in the 70s, and I bought it from the owner of a rental house that had been unoccupied and abandoned for years; this truck had been in the detached garage, under a tarp, for approximately 20 years. Here are the numbers and what I've been able to learn so far, maybe you can help with the last part of the assembly code stamped on the front of the block:
Block casting # 3782870 (62-65 327ci)
Casting date: J302 (October 30, 1962)
Head part numbers: 3890462 (2.02 "double-hump" without accessory holes)
Assembly code stamped: FIII3U (Flint, then either November 13 with U suffix, or January 11, 1963 with U suffix, or January 11, with 3U suffix. ) There is also a "09" of "60" stamped on the machined pad, offset to the assembly stamp, which I think is likely a machinest who bored the cylinders over .060, but I could be wrong there too.

I haven't been able to locate any information anywhere to help me identify the suffix "U" or "3U". Any information, or even your best guess is greatly appreciated. I know I have a pretty neat sbc regardless, but would like to figure the rest out.

The suffix codes for medium duty trucks are not published on the internet that I know of...but I have the book and the U code is a 1963 C60 truck 327.

hope that helps

 

Thanks so much for the info! I just had to ask the right person. That makes perfect sense for all the casting and date stamps too. I believe I will clean it up, check the cylinders for wear, new gaskets and intake, decent 350 or 400 trans, and run it. Thanks again Jim.

 

Hello all, I need a little help identifying this small block casting number.

 

TBA could be a 1970 chevy truck 350, 215 hp, LP Gas with TH350 or TH400.

at least that's what one old book says.

the code was also used in 1979.

Hi Jim,

cast date, E221
numbers on passenger front pad, 12J100510 and V0729CKB.
Regards Karl.

 

1972 Chevy built in Janesville, WI, engine cast May 22, 1971, assembled July 29th. CKB is a Chevy full size car 350 with TH trans.

 

squirrel rocks. jim has been my go to chevy guy for a long time.

just want to say thanks again for all the help you have provided.

 

I agree ^^^^^^^^^^^ Jim is always there to help ...
Thanks Jim !!!

 

Yep......Jim has helped lots of guys on here, me included. and I'm sure he doesn't mind.

That being said, if any of you guys need an engine identified and Jim happens to be busy doing his own stuff, there is a TOP SECRET website that will lead you to that elusive information. It's called www.google.com.

 

thanks!

google will only get you so far. I haven't put all my super secret books on the internet yet (because I'm lazy, not because I'm secretive).
