weight/viscosity of oil ---are you using only Castrol/Mobil1/Red Line/ Royal Purple oils and NON synthetics for the break in? ----tight clearances when rebuilt--restriction in the system lines kinked too many bends etc.---wrong oil filter restricting the oil--- too high a relief spring--- did you open up the oil passage on the pump to 1/2 inch from 3/8 inch ?-- remember pressure IS NOT Volume!!! restrictions increase pressure--also might contact 440source.com for their adjustable oil pump pressure regulator--- part # 200-1093 $24.95--- tele 775-883-2590---FED 387
