So I've got about 1 turn of preload right now on ls7 lifters, good enough or not so much? Zzp says to be between 1/4-3/4 turn on ls7 and 1/2-1.5 on stock what have you guys ran, and also I would get slightly shorter pushrods to correct this right?
Looser is faster if you have piston to valve clearance. Also depends on a few other things. The rocker to valve tip pattern, pushrod length, and oil pressure/idle speed. Real loose doesn't last as long overall. Kinda like all 3800.
