He does not need a dry sump... I could maybe see a baffled oil pan if he's running HPDEs with some really long sweepers, but c'mon. You're overestimating the "racing" thing here, big time.
I can understand the Baffled Oil Pan, do they make 1 for his LT1 Engine? I think this LT1 engine was only around for a few years, then the LT4 was around for a few years, and then the LS1.
If he does not need a Dry Sump, then he needs an Oil Accumulator.
