What? He put LS4 heads on a motor that used to have LS3 heads (so...it'd be a 4" bore motor or bigger) and its better? WHAT?! Do you even know what your talking about (judging from most of your posts, I think the answer is evident)? That's like taking RA4 heads off a Pontiac and installing some old 670's on it.

My motor isn't even in the same league as an LS3 and I'd put it up against anyone's Pontiac motor, give it to an independant testing agency and let them hash out the overall drivability of the car and the performance presented, and for giggles, we'll throw in cost. I mean c'mon, what is your problem? And who in the world drives a 99 Z28/T/A or Vette and has never driven it past 5500RPM? The automatic doesn't even shift yet, so your sayng it was never ever floored?

Anyway, theres something wrong with your buddies car, which is no big surprise if he can't even figure his heads out.

::shrug:: 13.0's, 112 traps, 3.08's with a stick, full creature comforts, and 25MPG. Yea, I can't drive.
