Here's a simple one for a few of you, but to ease my mind when should a hv oil pump be used....? 468bbc iron head motor, all comp internals, 10-1 comp, so it's a mild 500hp that will push 5500ish rpm. I haven't decided on my pan, either a open sump 8qt with doors i found cheap in ebay, or a stock style 6-7qt with a door like a mercruiser pan. I'm debating if I should run a stock style oil pump or a hv...I just don't wanna run the pump dry but I do wanna make sure it's getting what it needs to push the higher Rpms a jet boat runs usually. Ideas gear heads??!
