Help Decoding "Corvette" engine
Hello everyone, I'm new to this sight and came across it trying to find some information on a supposed Corvette engine block. It's a 3970010 with a partial VIN of C4F430079 and Suffix V0408TMM. I was told it came out of a corvette but I couldn't seem to figure it out for sure. Any help would be appreciated. Thanks!

Mines VO605TYU and I traced it to a truck block, I think to get 4 bolt mains, all the other bits match the original 1970 350/350 specs and the transmission is number matching.

Hi bh,
WELCOME!
First Post!!!!
Ah Yes! 'Mysterious' engines end up in Corvettes.
The '010' engine block was EXTREMELY common and literally millions of engines were built using that block in hundreds of configurations.
The 3 letter 'Suffix Code' is at the end of the engine stamp which identifies the plant the engine was assembled at... 'V' is Flint Michigan, the month and day the engine was assembled... 0408 is April the 8th, and…. TMM indicates either a 145 hp 2 barrel engine assembled in 1974 or a 170 hp 4 barrel engine assembled in 1980.
So there you go!
Regards,
Alan

Hi Graham,
I 'believe' the 2 bolt and 4 bolt main bearing engines use the same rough block casting.
It's the difference in the machining processes that result in a 2 bolt or 4 bolt bare block.
