I have a 355 that when cold running vr1 10w-30 she is 75psi and will climb higher if im hard on it, but I usually just keep it cool or drive normal for 10-15 minuts until she warms up a lil, prolly when the oil filter bypass kicks off, and pressure drops to 60 even when pushing the car hard, and never gets below 35 real hot at a stop light. I was worried at first but everyone respectable I talked to said those were all ideal numbers and Id be fine. Let her get warmed up and see. I think anything below 100 will be ok youll just no real soon if any gaskets are leaking because youll see blowby or whatnot creeping out. NO biggie tho.
