The hv pump we have only put's out a maxium of 55 psi cold and 25-30 psi hot . That's the most it's ever put out no matter what oil weight we try. So I guess it's either change relief valve or spring and get the correct pressure or get a standard oil pump and opening it up like some people do. The oil pan we have is really not worth the effort and time to fix so I am either going to get a 8qt moroso or the milodon 9qt ss pan. So what ever oil pump would be better to use in either application is what I need to use. Anyone reccomend getting a stock oil volume oil pump and open it up and get the right spring for oil pressure? Any power to be had or just a waste of time?
