Thread: Fresh off dyno

  1. #1

    Just came off the dyno with a new 468. Won't get into a ton of detail, but I will tell you this. 468, Pro Topline heads by Abbott Racing Heads, Super Victor, one Dominator on gas, no juice.......... 858 HP @ 7200 RPM // 696 lb/ft torque @ 5900 rpm. The heads are 24 degree Chevy design. The heads and intake were fully ported and flowed by Abbott Racing Heads. Getting a blown alky 509 ready next, then a couple of carbed, nitrous 540's with the Pro Topline heads. Hey Steelcomp, had to get back to a little R&D after hearing about yours. That's about 50 more HP than we'd ever made with a 468 with a single carb. BTW, a box stock 8896.

    Hell, I was impressed. A lot of credit on this needs to go to my cylinder head guy. That's where the HP comes from. The rest of it is just a big air compressor.

    We did a 476 earlier this year that made 828 @ 7100 and 704lb/ft of torque @ 6100. That was a PLJ legal motor. The 468 has a ton of port work done.

    Hey Dallas........... Ain't nothing like breaking in a newbie, especially one with a Ford. Just be ready for Test and Tune at the first Waco race and we'll see what that blue oval stuff will do. I've seen many a fella walk away with a tear in his eye. I'll even help you get it ready. Which boat are you gonna run?
