340 oil pump

Bob this is something I've read alot on because there's alot written out there by guys that can prove either is the right one to use. I have still yet to find the correct answer. Some say you can't use a HV pump with a stock oil pan or you will suck it dry. Others say it's no problem. In fact I have a buddy with a 340 Cuda that has a HV pump and a stock pan and he races some and has no problem and his car runs high 12's and he put it together 6 yrs. ago. Some other guys say use a high pressure spring and that's all that's needed. Then others say that's not a good thing either cause higher pressure means higher oil temps. which is true so go figure. IMHO if you run loose clearances run a HV pump. If you run stock clearances run a stock pump. A deep oil pan is never a bad idea either. Also consider deburring the block when rebuilding it so oil drains back faster. And if you run a windage tray I've heard to bend the drain flaps out straight so they drain quicker.

Good luck with your project.
