Jegs if you have the racer discount or Dennis at Moore Racecraft or Joe at Hyperaktive.

Are you looking at the Hp or Dominator?

Where's the fun in that? This is my weekend car, I don't care if it gets 2 gallons to the mile. It's my first v8 anything, and want a little chop in idle. I'll drive my 32mpg cobalt ss if I'm worried about mileage.

As far as hp, screw 500hp, I got turbo hayabusas's that make more then that on 1.3 liter engines. The 5.3s can handle 800hp reliably on e85, as you know. I don't give a **** if I leave the crank at the line, I'll get another $350 long block and do it all again.
