408/AFR/T-rex on engine dyno I was pretty amazed at the power this motor made. Hans Feustal did the machine work, assembly and I used BS3 to tune it. It made 633/578 torque. I told Hans we would be lucky to get 600 out of it..lol.
Good numbers from two tried and true parts...AFR's and the T-rex cam.
Other mods to the motor are:
stock FAST intake
NW 90
Kooks 1 3/4" headers
compression was 11:1
pump gas

Not my motor, so I didn't grab any sheets. I don't know a damn thing about engine dynos, but I think that it was around .4....sound right? I just paid attention to the WB to make sure it was ok during a pull.

Not bad at all.
Don't underestimate the LSx platform

The loss through my OEM Stock drivetrain to the tires was 64hp...
