Indy single line pickup, 7 quart milodon pan, 8 quarts total with filter. I am running .003 on mains, .0025 on rods. I have a .050 jet in each head feeding harland sharp rockers. 440-1s. Brad Penn 15-40, wix racing filter. I changed the guage to a manual, have 35 lbs at idle steady hot, throttle open I can see it go to 80 then drops to 60 like the pump bypass opens. Is this ok or can I shim the spring in the pump. Melling pump, Indy cover. Galen



does it drop back to 60 lbs with no load on the motor at 3500 and higher rpm, or only when under a load?
