How about a 727HP 572 Cu In Crate Motor directly from Chevrolet?

Here is a bolt-in 9 second capable 572 Cu In Rat motor you can purchase today directly from the Chevrolet factory.

This motor would be perfect for a serious bracket racer. Or as your weekend cruiser, you’ll just need to have access to 110 octane gas due to the 12:1 compression ratio. And you can have this engine delivered ready to run rather than waiting weeks for an engine shop to build your motor. If you don’t mind slightly less performance, a 9.6:1 compression version is also available that will run on 92 octane.
