Is anyone among us running a 60 or 65 psi oil pump in their 5.7 rams? I've installed a comp 260 cam , springs, push rods, under drive pulley, t1000. And I bought a Melling performance oil pump with 3 options for pressure springs. Factory 5.7 oil pump @ 55psi, and it also comes with 60 and 65 psi. I am curious to see if it would benefit me to run the intermediate spring at 60 psi??

Maybe, but my Magnum has almost 300,000 miles, 5.7 hemi, sidewinder cam, pushrods, valve springs, 6,000 rpm shifts, and still original oil pump, water pump and P/S pump. Had many nitrous runs down the track, still burns no oil.:smileup: Ram has hotter cam, 6200 rpm shifts, nitrous, etc but only 210,000 miles. Love to hear the Chevy guys tell me what a pos the hemis are, hehe.

Thanks guys for the response. I wen head and went with 5.7 oil pressure spring. I'm not gonna run any aggressive mods.

Old rule of thumb used to be 10 psi of pressure for every 1,000 rpm.
Might not be relative anymore,but it's something to keep in the back of your mind
