Help identifying

[ericcarr2000]

I just purchased a new motor/heads for my boat. Can someone help me identify the years if I give you the casting numbers?
Heads are 3917215, block is 14015445.

block is 1978-1990 7.4 liter (454) truck/RV/etc

heads come back as initially 1969-1970 small oval heads (101cc chamber) for a 396/427

i would probably sell the heads and look for something that came off a 454, especially if you intend to run a domed piston.
