I have been told that high pressure pumps can starve your main and rod bearings by pushing too much oil to the top of the engine hence creating friction and ruining your bearings. I was told that a stock pressure pump was the way to go on a 440hp 383 stroker that i am building-hmmmm???? Now, i know that the higher rpms you turn that the more pressure you need to get the oil out through the crank and to the bearings due to the increase in centrifugal force. What do you guys that have built some high hp engines before think?? I am really not sure which to use and of course i don't want to starve my bearings. Should i enlarge the crank bearing holes like some of the engine building books suggest-it is a brand new scat crank and i would hate to slip and mess up the journal surface.
