by the way, picked up the felpro once piece oilpan gasket. my god, that thing is amazing. im going to see if i can get those same gaskets for my valve covers.
some are off from the factory by design.....i know on a 77 350 they are clocked away from the keyway because of the timing tag.....check the original......good luck.....

if the new ones the same way, i think im going to bring it home, as long as i can bring it back if its the wrong one. my motors still fully assembled so i cant check it, and i wont be getting to this project for another few weeks.

the Dorman and Pioneer are probably the same balancer. I saw no difference and sold them both

FYI, whatever you do, don't re-install one of those cheap chrome timing chain covers, they will leak!!
