    Hi all, I have what I think is a 427 in my 72 c10, am about to buy an Edelbrock EFI system for it, but decided to decode the heads to see if I should change them at the same time. Heads are 3933148 , intake is 3883948, which shouldn't fit those heads if they are truck heads. block is a 3963512 with a T on its side, High Perf Passenger K23 Vin is CE 954059 so a crate engine from 69? Are the heads up to the task? A new intake comes in their kit.
    Cheers in advance. Pete S
