Ok, i've been reading about this for the last hour through searching but i'm still confused. I'm buiding a 383 w/ lunati crank h beams forged pistons and the LE3 heads cam. What oil pump/pan do i need? I see alot of people saying you can run the stock pump with a upgraded spring(not sure which spring) and still run the stock pan and be fine. Ans then other pwople are saying you need to run the canton pan and a hv pump. I'm soooo confused right now. Which do i need to go with.

As far as I know any stroker kits or rebuild kits for our cars came with HV pumps.. I would assume the stock pan would work fine though.

The stock pump provides adequate flow for a stroked LT1 turning some decent RPM. I use the stock pump, blueprinted, pickup tack welded, and an 80psi pressure relief spring (aka "the white spring"). I use the stock pan and a windage tray. Some very minor tapping of the pan to clear the crank - you can't notice it, its so subtle. Engine has a 7,200rpm redline, spraying a 300-shot of nitrous. No problems with the oil system. Same system also worked fine on a 383 running 20+# of boost, and making 1,125HP at the crank. No problems with the oil system, even with 1.3x 60-ft times and 3 foot wheelstands. Well.... actually, the pan did see some damage after a heavy drop from one of those wheelstands, and required a little straightening....

Ok that sounds like a plan. You don't happen to have the part numbers on hand do you?
