Lets see, the pump is a millings HV, I'm running Valvoline 20-50w racing ZR1, the pressure pegs at 80 till its warmed up, then pressure drops to 70. I pulled the pump last night, the relief valve wasn't stuck, but the spring seems to stiff.
Put 10W30 in
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

Is that reading correct ?? ( off the dash gauge, or a seperate gauge plumbed in ? ) Do you run breathers on your valve covers ? I have 80+ psi on start up, but it comes down after a few minutes of warm up,,,i also changed to 10w30 to get the pressure down a bit We also "shaved" down the spring a bit on the oil pump to lower it a bit. good luck

Way back when McCandless and all of us went through a period of cranking new small blocks and having monster pressure. Finally Herb figured it out. He inspected the Melling HV pumps and discovered they had milled the pocket for the plunger some 100 thou shallow or whatever and it caused the excessive pressure. He called them and explained and as I recall they did notta. So...I have always used std volume pumps on small blocks and stayed away from Mellings as a rule when possible.

Why is anyone running 20w50 in a new motor?
May as well dyno it with the ebrake on too.
I would drop the oil weight down to a MAXIMUM of 10w30 and closely inspect your oil pump's relief valve. 80 psi is too much, period.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
