Hello, thank you for allowing me to joining this forum.

I am hoping someone can help me identify this small block.

I have found some info on the casting # and one of the stamping, but having a hard time with what I believe should be the partial vin.

So far what I got from the casting # is 69 only block, 327 or 350.
The one stamp Tonawanda June 5 and most likely 350 automatic Full size of Chevy II
Then i can not find any partial that starts with a 7.

Thank you for any info
Morley

Casting # 3932388
Then,
T0606HM
And partial vin 791154364

You need to search for the factory service manual for the model year of your car, go to the page that breaks down the VIN. page will look similar to the one i attached from my 1986 C30 manual. Should be about pg 4.

Let me know how you make out.

Thanks Half-ton for replying, problem is all we have is the engine. Years ago someone listed it as coming out of a firebird. I know Canadian Pontiacs did use SBCs at the time. So we are just trying to figure out what its use really was. It's been in our building for about 40 years and anyone who would have known anything is long gone.
Thanks again
