low oil pressure in a sbc?
we just put a 327ci together. the chank was turned 20 and the mains and rod bearings are -20. the motor has 5 lbs of oil pressure but when u get on it it has 25-37lbs. couple people said that if it has pressure run it and others said that it wont last breakin time.i know a guy who had a motor built that had 7.5 lbs and over 750 horses big block chevy that had over 500 racing laps b4 it was freshened. please help us b4 its 2 late.
General rule is 10 PSI per 1000 rpm..but 7.5 is low to me. 25-37 at 5000 psi is not good.Are you SURE of that reading with a separate pressure gauge and not the electronic one?
