Quote: Pressure feed if you can afford but...keep the darn spring pressures down on a street unit Most will run like crazy with 425 lb open Yes you would want 650 or more on the strip but on the street it is all about NOT killing the lifter When you are at idle, arm out the window, strutting around the cruise--that lifter wheel bearings can be red hot from lack of oil Most folks run WAY too much spring pressure on street rollers Morel pressure feed is the way to go for solids anytime and Never restrict oil in any way whatsoever --it kills lifters.
Agressive profiles and lack of spring pressure is harder on rollers than anything. And if you run a morel style lifter you usually have to restrict oil in most setups
