does anyone make a full sump rear sump oil pan, i have a couple of the truck pans and remember at one time seeing someone here had some tips on modifying them with trap doors and sump traps and such, id be open for that but im wondering though why none of the pan manufacturers make a full sump pan, i know some of the custom builders do and billet fabrications pans are some of the nicest i have seen but quite expensive. what pan do you guys recommend for all out drag racing, hard leaving clutch car.
also the high volume pump that precision has, any reason to add the high pressure spring and disk or leave it as is ? maybe pull the plug, thread it, make it adjustable ? all old school stuff i guess,
