Casting Number / Engine Size
I recently bought a motor and I was told it was either a 283 or a 327 out of approximately a 1965 Vette. I've researched all the numbers I've found on the motor and all I can tell is that it might be a 327 or a 350 from the late 60's or early 70's. The main things I want to know is what year it is, what vehicle it was originally made for and what size it is (283, 327 or a 350)? ... Mainly the size though. Below I'm listing all of the number and places I've found them and see if anyone can decipher them for me. I wrote down the numbers as closely to what the appeared to be as possible.
I believe these letters/numbers were on the front of the block. C4F415069 V03061JC I think these letters/numbers were on the top of the manifold 340234 R B274 These letters/numbers are on the back of the block GM21 3970010 These letters/numbers are on the exhaust manifold GM336710 These letters/numbers are on the block inside of where the bell housing mounts to the block. 010 020 509 H18 PS78 2 7/64 |
If the Block is Okay, It's a Keeper!

Look here. about half way down the page they get into the letters I just checked a block I have 3970014 T0501CNJ and the CNJ code was there. My heads 3947041 High horse heads.... This is for sale as I am building another 350. |
Thanks for the info. I cleaned the engine more today and realized one of my letters were wrong. It was the one from the front of the head. I originally put V03061JC but the correct numbers/letters are: V0306TJC
