just recieved a melling oil pump for my cam swap on saturday. it includes a +10 psi relief spring installed in the pump. it is also supplied with a stock pressure spring. heres my question... im running the factory ls1 lifters, do any of yall believe the increased pressure will aid high rpm lifter "pump-up". if so, would yall recommend installing the factory pressure spring? im not doing anything else, just a tsp 233/239 cam, prc dual springs, pushrods, ls2 chain.
