i was wondering are all main caps for a dz block the same #? i have a early 386 block with #'s 2482 on 3 of them and the one up front has 3951 on it. one has GM 186,GM 51n,GM 83n,and GM50 n. my question is i have another dz block, this one is a 618 and i don't have caps for it. i found a set with the #'s 3412, i know they will work but are they possibly off a 350? or a 302? thanks frank
