Can someone ID this block and heads?
I just got my motor to put into my '67 and would like for someone to check the numbers for me. Time to finally swap out the 250...
The block casting has: 19 GM 3970010
The heads have: GM 54 3927186
The motor just came out of a friends 79 L-82 'vette but I don't think it's original. I do know that it runs very strong though.
Thanks ahead of time!!!
