    Anyone know why a 99 vette has 350 hp and a F-body only 305 or so? Is it exhaust or engine internals?

    Again gm claim, how would corvette guys react if they found out the motors had the same power. I f anything the corvette was overated, the thing puts down roughly 290rwhp because of the irs.

    A magazine did a dyno test in 98 they had the same rwhp. But the vette weighs less, that what makes them faster.

    Ok, thanks. I'm puttin a 99 in my Jeep. I could ask u guys a lot of questions. I'll use a camaro program but it's a vette motor. Since there was a 40hp difference, I was lookin for anything tangible to make sure I don't lose any power.
