well ok i spend way to much time on bearings have a cabnet at the shops with $100s of bearings i just did not like or split to get size i wanted . even on the stock stuff its a big deal with me so i do not get a call thats .she runs fine but its low on oil psi for stock engine with a stock pump . if the rods come out on the big end your going to get that .i first check the housing bores so there were i want them on rod bores and mains .guys like me may check your size for nothing or abit of money if they did all the machine work .that why you never want to piss off the guy that machines your stuff if your not paying him to short block or long block your engine
