First Generation Firebird-L Mailing List ......................................................................... Hmmm, 10psi/1Krpm seems a little low - that would mean 10 or less at idle[?!]. Ten psi is barely enough to get oil up to the rocker arms. From what I've read on all GM engines, the normal operating spec is 40-60psi, [perhaps 30-35 hot].
re: h/p pump; bearing clearance if far more important than journal size, [no matter the what brand of engine]. If the bearing clearances are set to nominal or on the low-side, there's no need for a hi-press pump. The collective clearances in the oil system [& oil viscosity] have the biggest influence on pressure, not so much the pump.
