This thread got me thinking.... As i have assembled my aluminum SBF (302 mains, chevy rods) with forged crank and checking "gaps" according to factory (iron block) specs, there might be a 0.001 undersize set of main bearings to get the clearances correct in respect to the alu block?
Oil pressure is 25 psi at warm idle (1250 rpm). 50- 60 at cold, 40 at room temp.
although, I have seen people saying idle
oil pressure down to 10PSI is ok, I am concerned...40 at hot idle? never seen it that high, even in iron blocks... Should I be concerned?
