I would have put a Pontiac in it too. Try to buy or build a 5000hp capable unit? Time, spare parts, and reliability won’t be on your side.

Guys! I love the Pontiac engine too. But you can’t do what you can with a 481X to this level simply because of the size limitations. My 572 is 4.5X4.5 with free flowing heads built for that size of bore (no one, not even Bill or whoever is your favorite, can build a head that can match because of the space constraints in the physical size of the block and bore, period!) so if you are ever on a sticky track you will get pulled on the top , period. And yes, billet components are on the shelf with at least 3 suppliers so you can keep racing when you break, and 4500hp will hurt parts no matter how good you are. If it’s a slick track everyone has a shot!

As for the BBC and Hemi discussion, a 481X is a stand alone specifically designed race engine. It’s no brand of engine other than AJPE.
