It is probably the most consistent COPO that I own.

The throttle body is the same one that's on my 302. The cylinder heads are the same castings as the 396/375. I have a pretty good idea of how Chevrolet's test session went. I also have my own data. I ordered the car with the understanding that the HP would be 430. The 500 HP rating that the combination was given is a big disappointment to us.

As delivered, the 572 made just a little over 720 HP on Jeff's engine dyno. My 302 made right around 600 HP on Holley's when I lent it to them to test the Terminator X.

I have no doubt that there is room to pick the combination up. We are experimenting with some stuff right now. I just can't bring myself to throw a big pile of money at this car.

Come now!
I saw that combo go 8.7’s in SS trim with my own eyes!

Yep, a BIG pile of money that got HP for the showing.....

Each to their own, but not what I want to do with the money I earn.

The 572 2022 COPO Camaro would have received a HP reduction if it was submitted for review in Stock eliminator.

We talked about that, but in the end we decided not to request one.
