What kinda oil pressure is your motor running?

[BADPURPLE70CHEVY]

Just finished my 406 recently and was wondering how much oil pressure on you running fully warmed up in drive at idle? Just curious. Mine is about 25-30 pounds in gear after i have drove it a while. When i get going down the road cruising it hangs around 55-62.

Thanks I read it just now. Anybody else got an opinion on oil pressure.

Do you have a high volume oil pump in your 406? In my 71 nova with a 406 I have about 25 to 30 pounds at idle when warm, and It darn near pegs the needle when at full throttle, My pump is a Melling high volume

No high volume oil pump. But if i get in it pretty good it goes to about 70-75. Just worried about the idle in gear pressure after warm up.

Thats plenty! now get out there and drive the wheels off it!

no problem, if i remember right 10 pounds per 1000 rpm is enough per the engineers who designed it a million years ago. If you had more i would be worried, my 406 in my 10 inch tire drag truck would go from 80 pounds to about 10 right about the finish line at the dragstrip. it was a high volume/pressure and was sucking the pan dry, but i was turning it 8300 rpm.

Just got alot of money tied up in it. Guess im worrying for nothing.

My 350 in my caprice has about 10-15psi @ idle(550rpm). I was told don't really worry about idle, worry about it at rpm.

the 350 in my truck is the same way, really low at idle and about 45-50 cruising speed.
