Melling oil pumps, difference between the High Pressure and High Volume models???
In the middle of doing a cam swap and considering upgrading the oil pump while I am in there. What is the difference between the high volume and high pressure Melling pumps and what would one use on a stock motor with the usual bolt-ons and cam. I know I have seen threads that suggest High Volume by why it and not the High Pressure.
Thanks in advance....
