I was on here a few months ago, which no one will probably remember. anyways, i have a 1969 351w block. my rotating assembly is from a 1985 351w. i was told on this site that I could still use my rotating assembly, but i had to get some machine work to my crank. 69 cranks (from what i was told) had oil slingers and a 2 piece rear main. 85's had one peice rear mains, and no oil slingers. I understand this, but everyone else i have talked to (off this site) has no idea what i am talking about. a man at a crank shop told me all i could do is hope it wouldn't leak. well that's bull-ish to me. i want a honest, no bs answer. can i use it or no. i do not care if i have to buy an updated seal or whatever it takes, i just want to build my motor, the right way without any leaks. CAN SOMEONE PLEASE HELP ME???????
if you want to talk to me directly to make more sense, please feel free.
