It's a 3.8 liter actually, and that thing WILL spank you...unless he spins his tires.
240hp, 260ft-lbs torque on the series II, 260/280 on the new Series IIIs... too bad they're UGLY now...



The Series II is actually a 240/280 and the Series III was originally meant to be 280/280, in the concept car, but they decided to cut the HP for several reasons:

1) Because SLP produces a current Stage 3 GTX package for the Grand Prix GTP that pushes 270/280 and a 0-60 of 6.2, 1/4 in the mid to low 14's I believe. If they produced a 280x2, they would have had to use the same modifications that SLP used to produce the car stock in its Comp G package (180 deg thermostat, 3.5" pulley, chip, cat back exhaust, don't know the pipe config, etc). The Comp G's, btw, are automanuals and already pulling those numbers stock, 6.2 and ~14.4-14.6. SLP would have lost a lot of business (-;

2) Because the front axle, I'm told, wore out too quickly in road tests with that much power. Don't know why 10-20hp makes that difference, but who can say.. it's a pontiac ?

3) Pontiac loves to put out its cars in measurements of horsepower per model per trim. Starting with 175hp in the Grand am, moving up to 200hp in the Grand Prix GT, to 260hp in the GTP, to 280hp in the new Bonneville, to 345 (or however many) ponies in the new GTO, etc.

Also, the Pontiac ATX's are not slushboxes. Their motors are aging, old school, 12V gas guzzling kittens, but their trannies aren't too bad. I got my Ford/Mercury 170hp/160ft\lb slushbox stomped by a lower powered and heavier 150hp\159ft/lb Grand Am ATX slushbox by at least 4 feet. Performance shift is a neat thing, plus those buggers have a lot of low end power and pull hard during shifts. 1/4 mile would have been a different story I suspect
