The 572 makes about as much power per cubic inch as the '69 350/255. The 572 makes .023 hp per cubic inch more than the 69 350/255.

Now that is progress using an ECM. Impressive!

We’re those the ones that were recalled for lack of power?

Guys I started this post to let everyone know that Chevrolet was 'back in the game' - and not to argue over horse powers -yes , I must agree that the 572 is rated by the GM folks a bunch low but you must also agree that all of the 'big 3' have been guilty of this practice over the years .All that plus the horse power is only Chevrolet's number not the official one used and accepted by the NHRA as far as I know so we'll see.

I guess my real point is that since the manufactures are in the game Stock and SuperStock have received more attention than ever and that can't be bad .
