Trying not to post too much about our setup online, it is a race . Its more of a generic question trying to find some inexpensive ideas on how to keep a SBC alive. Its basically a older pre 80s 350 with mild cam and a quadrajet. We are heavy on cooling radiator. We have a external tranny cooler.

Right now running 5 quarts.

If you are running a 5 quart Oil pan DO NOT RUN a Hi Volume Oil Pump.
This is a big mistake on a engine that is running for a long period of time at high engine speeds.
If you run a High Volume Oil Pump you can a will run the Engine out of oil.
Run a stock oil pump with a high pressure oil spring you should not run the Engine out of oil as fast.
Radius the oil drain backs in oil valley of the engine block.
What kind of oil do you use (Viscosity and type)?
I realize you are trying to keep some things secret but how can we do that without knowing more info?

run EOS or some other addative in the oil. i would use shell rotella oil or brad penn.

If you are running a Flat tappet Camshaft you need to run an oil with ZDDP additive in it above 1200ppm. Other wise you wipe the camshaft out. Brad Penn and Shell Rotella both have the ZDDP additive above 1200ppm. Most all of your racing oils like Valvoline VR1 and Quaker State Racing oil have high levels of ZDDP (Zinc) in them.

diesel oils usually have alot more additives as well.

its lemons, he probably doesnt have the $ to invest in a pump like that anyway. But the high pressure spring should not suck a stock pan dry at all.
