340 oiling system

Oil pan, pump, windage tray, etc... What do you use, and recommend?

I'm gathering parts to build a street 340, 400 HP goal, for my 71 Scamp.

I already have a factory windage tray, and a new HV Melling pump. I've read some difference in opinion on using these. So I'm left wondering about my application, but right now I plan to use them and think I should be fine.

I have a used pick up too...should be okay to clean and reuse, yes?

Should I go with a factory oil pan, or will I need more capacity for the HV pump?

What about stamped numbers in factory pans? Is there a list somewhere on the net for all the applications by stamp #? As near as I can tell, the correct year and model for mine would be the #294.

I don't really want to spend a lot of money on an oil pan, and also the possibility the aftermarket ones not fitting properly with the k-frame, steering linkage, exhaust/headers, etc... So I'm leaning towards a factory stock pan, unless I'm told I should use something else for better performance.

Thanks!
