Deciphering Engine Codes
Doing some research on a 350ci motor I just purchased...It came out of a 72 C-10 2wd with a 350thm...The deck stamp is T1029CMA and the casting number at rear of the block 39700(1*)4 (not sure about the "*one")...The casting date is 1/23/73. This appears to be a factory 4bbl intake and Quadrajet...Heres some pics...Any help would be greatly appreciated Thanks in advance!

Re: Deciphering Engine Codes
T Tonawonda assembly plant
10 October 29 29th day of October CMA 74 L65 350 2bbl comes back as car engine, if you have a VIN code stamped somewhere in the block that can be decoded as well. 3970014 68-79 350cid block

Re: Deciphering Engine Codes
It can be several places. The engine assembly code pad, but I suspect you would have seen that. Try the block above the oil filter and the bellhousing flange for alternate locations.

Re: Deciphering Engine Codes
Quote:
Base on your provided casting date and assembly code, I gave you the most likely applications. 74 L-65 350 V8 8.5cr 2bbl 145hp In that list you will see there is in fact a 74 camaro application. While nastyZ28 has a lot of information there is a lot of missing information too. What they are trying to say in your quote is a Van Nuys, California assembled Camaro. But then they also only list 3970014 as a 70-73 block which it is not. Actual listed uses are from 68-79. Based upon your assembly code it is most likely a 2 bolt main. While it might have a factory 4bbl intake and carb that does not mean they are original to that block and being 40 years later in a vehicle other than it was originally built for pretty much makes everything a gamble. Might try looking up the intake codes and dates too along with the carb application.

Re: Deciphering Engine Codes
Water in oil usually means either a blown head gasket, or a cracked block or head... Keep fingers crossed it's a gasket or one of the heads.
Could be a water jacket gasket from the intake manifold as well. But you should get the block and heads t a machine shop to magnaflux for cracks. Gary
