Went back to the dyno yesterday to dial in the tune a bit more...

Stock bottom end: No, forged Mach1 10:1 compression

PD unit: Whipple 3.4 with Crusher inlet

Pulley size and boost level: 2.75" - 29psi

Fuel system: Triple Walbro 455s, full return, ID1000s, Fore Triple hat

Tuner: SCT Tuner Manny Alvarez@HPP Motorsports

Other notable mods: LT's, 3.27's, 96 Cobra intake cams, built 4r75W, e85

RWHP/RWTQ: 742/774

Other notable was the blower belt was slipping badly above 6000 rpm. Need a better belt and a little more tension. That should put it over 800 easily.
