CB,
Those are some impressive stock #s. I know the general has been known for underrating unlike Ford(ie 98 or 99 Cobra). But if you use the 17-18% drivetrain loss rule it gives about 360 at the crank. Where did you see 307 at RevX, Coastal,...?
I guess more than anything this pisses my off that my LT1 only made 232 and that a few minor mods. That has all changed now though. Take it easy
