SBC numbers?
I am using this motor to move a project around, it runs good but if its a 4blt block I might need to take a little better care of it. I am having trouble narrowing down if its a 2 or 4 bolt block.
Heads are (F270) & 3927186 which should be 69-70 302or350. The back of the block is 3951509 which is 70-71 4 blt or 74-80 2 blt. It came out of a 77 K10 4x4 truck. The front pad has F1006TLD and under that it has C9S118352.
With that suffix can anyone id this for me?????
Thanks

What is the casting date right below the casting number?
Is it going into a build, or making a trip to NM?
