This is why I am asking. I have seen both 903 and 904 listed for Mopar. Cab says 904 is Chevy. Dogdays says 904 is Mopar. Maybe it doesn't matter. Just whichever one fits best? shruggy
Is there a minimum and maximum clearance you guys like using before a lifter either galls the bore or bleeds off too much oil pressure? Or do they chatter around if too loose? My Indy block does not have any lifter oiling. Do specs change for that?
