First off, let me say this. I am disapointed with the Gt 500...it was suppose to wiegh 3,600 pounds have a detuned ford gt motor w/ a twin screw. Rant over!!! Okay, I'm not talking Saleen Extreme 550hp@500 torque.I'm refering to the s/c Saleen. It looks better has 435hp 425 torque(twin screw) and weighs 3,550. Compared to a Gt 500 which is 475@475 and weighs 3,940(whopper) 400 more pounds equals 50hp. Both should be underrated. The thing I'm in a bind about is the 330 5.4,is the Saleen going to be as easy to mod as the Gt 500?
