Had one of those on a 73 Cuda I raced for a while, Jay. Not sure it would flow enough for a street deal though.

The Gremlin
Other than engine work/swapping, the Gremlin was untouched from Drag Week 2015. So Dale had a grand total of five passes since he had added lighter springs to the new front end setup, and now he would be running an engine about 75 lbs. heavier. The 547 that he picked up along with cash for his 572 Hemi, had turned into a complete nightmare.
Once Dale got the World iron block tore down, he decided to move from the 4.395 bore, straight to 4.500 effectively building a 572. He wasn't exactly comfortable with the spray bar oiled Jesel rockers, so he went with his oldest set of Indy -1 castings, that he has had around since the nineties.
He found himself waiting so late to order a cam that he was limited to whatever solid flat tappet grinds Comp had on the shelf, and he ended up with a 290@.050, .650 lift dinosaur that probably had two inches of dust on the box before they mailed it.

The fact was, the Gremlin was a more of a plan B, safety net deal in Dale's Drag Week 2016 approach, and the 572 was more of a "what parts can I toss together in 2 weeks, and make this happen" last ditch effort.
