So I’m another Chris moment, I screwed up. Was installing the oil pump today on the 440 and noticed at the bottom of the instructions, it reads “This is a high volume, standard PSI oil pump. Requires a wet sump and 7 quart capacity oil pan”… so much for that stock A body big block oil pan
So weld in a kick out or just run an extra quart of oil if you race it. I did that with my old race car. It would suck the pan dry about a 1000 ft. Ran an extra quart and had 90 psi at the finish line at 7800rpm.
