468rwhp is pretty damn good.
Between the doubler and automatic I would guess he's loosing 30% of the power he's making at the Flywheel
Let's pretend that he's making 1hp/CI at 555 CI. SO 555X.30=166.5 555-166.5=388.5.
I'm guessing there's two things happening, he's making more than 1hp/CI and not quite loosing 30% through the drive-train.
Ya, this motor turned 629 HP at the fly wheel not tuned in yet on just motor, the rest of the tuning was done on a chassis dyno, we figured 30% to 35% loss to the tires with the Lo- Max 205 & the ORD doubler with 44" pitbull rockers!
This was done at 5,600' elevation.
All the specs to the motor are on this build thread, Dart M Block and all the good stuff, not a race motor buy any means but a really good, strong, reliable motor! It breaks a lot of ****!! Lol Have to go to the Jana 76 front because I can't keep the 60's gears together, every time I hit the NOS I lose teeth in the 60.
