Do you think that Jim B's 396/375 HP Camaro makes 405 HP?

First the 572 was never installed in any chevy,it is a crate motor only.

The majority of 2022 COPOs were built with a 572.
For the record, the order form for my 572 COPO says "NHRA rated at 430 HP". It would have been a good combination at that HP. At 500 HP, I am not a fan.
