Watched a video recently about high volume pumps in LS's. Don't remember if it was Melling, Holley, Steve Morris or.... but they ran into problems with road race cars. Higher volume is fine for street strip cars but the sustained high rpm from road courses would suck sump dry without a baffled pan. I know we've all heard about that back in the day with traditional sbc/bbc. Never bought into it but now ??? And I have the high volume pump and no baffled doors in my pan. I wanted to do some autocross but at the rate I'm going I'll be happy to do some street light acceleration hi jinks.Oil pressure is waaay overrated. Oil volume is not.
I have some experience with this (I’m not an expert so take my thoughts with a grain of salt.) I ran a Mellimg M295 from Advance Auto on a 4.8 for about 2k miles of severely heavy, stupid abuse. It never seen 55 psi of oil pressure at darn near 8000 rpm’s. A lifter went out of that motor and it was quicker for me to swap in an aluminum 5.3 than swap lifters. I installed another new M295 pump and the same deal, 45-55psi at WOT at 25+ psi of boost. A couple of people convinced me that needed more pressure so I shimmed the relief spring by .100”.
Now I have 65-75 at WOT.
Both motors have not experienced any oil related issues. And one might say that I FLOG them pretty hard. I ran the 5.3 out of oil before I discovered that it was out of oil at over 7k before. Then I started adding an extra 1.5qts to the pan - still runs properly with no issues. All of this with one bolt
In the pickup.
You need to have the correct O-ring, they aren’t all the same. BTR has an excellent segment on this - read it.
