What's y'all's oil pressure readings on 5.7 vortec?

[Black stallion]

My truck holds 60 when cold, 40-45 when driving and 25 at idle is that ok at idle?

Yeah that's fine at idle...mine's around 20. In general 10 psi per 1000 rpm is the minimum for a SBC

 

[trailer-trash]

Mine idles just under 40 when warm....60ish while driving...but I use a quart of lucas also.

GM oil pressure gauges aren't dummy gauges like some other manufacturers *cough* Ford *cough* so that's exactly what's supposed to happen.

This is pretty much what mine runs to. Like Andrew said, 10 psi per 1000 rpm an you're fine.

Andrew could you tell a difference with your shorty headers I been thinking about the pacesetter ones ? How easy did the manifold bolts come out?

 

[wintimidator]

sounds exactly the same as mine

Honestly not really...i'm not sure if it was the headers or the cheap y-pipe but the fit between those two was pretty bad and it leaks quite a bit...I'm actually looking into getting long tubes now and I'd suggest saving up for those to anyone looking at shortys. As for the manifold bolts, I dont remember them being that bad to get off

Is it bad if it never gets to 60? When driving mine never gets higher than about 45?

Do you ever go over 4500 rpm?
