What will it run? New 572 build

That’s the thought. When we made that change to my friends engine on the dyno, and I mean almost identical 572 to this one, it gained 18 hp and 19 ft lbs of torque but gained a substantial average throughout the entire pull. It was pretty crazy to see.
Nice gains. I tried a few different spacers on my and everything lost power compared to the super sucker 2 inch spacers
