I bought a 80 Formula Firebird awhile back that someone had replaced the 301 with a SBC that had 461 camel humps on it. Today I finally got around to checking the casting numbers on the block or trying to anyway. Anyone have any idea what the numbers may be? The head castings are 3782461

Hers the pics  of the numbers after I scraped it with a wire brush


Head Casting #  3782461

The heads are from 1961-1970, and fit 302/327/350 sbc.  

The casting on the block looks like 3782870.  If so, it is a 327 from 1962-1967 car or truck with a 2 bolt main.

OK so the numbers come back

Heads... 61-70 Dual Quad FI & 4 Barrel Corvette 2.02/1.60 64cc
Block....  62-67 Car/Truck  2 Bolt

Would that make it a 62-67 Vette motor? Didn't see any vette motors listed specifically  with the exception of 55.
