Does anybody know why the new GTO's are rated at 350hp and 360torque? Isn't it the exact same Ls1 as found in TransAms and Camaros? If not whats the difference between the ls1's in the TransAms/Firebirds and the GTO's/Corvettes?

Considering the vast majority of F-bodies dyno in the 300rwhp range (which is 350 crank hp), there really isn't any significant difference other than what GM decided to advertise. Well, it would have been tough to advertise it @ a lower hp figure considering Holden has been advertising 350hp all these years. Holden never had to compete with the Vette though, and that is pretty much the only reason the F-bodies were underrated to begin with.

There is very little differences none which is in the motor!
I don,t think they will be recognized as a true sports car again I think it will be catagorized as a car like the impala!!!
Just my intuition.

Not to get off the subject but there are 2 things that I like about the GTO besides its name and it uses an LS1. It comes with a strut tower brace and the plugs and wires are easily accessible. However, there is no extra room for a Supercharger or Turbo that I can see.

So one guy says the intake plumbing, exhaust, and cam is different. Another says its all in advertisment. Which is it? So do the Ls1's in TranAms and Camaros really make 350hp and 375tq?

Ever notice how a Vette sounds different and has a different intake system, even though it is an LS1 (exc. the Z06), the same holds true for the GTO and TA/Camaros. I believe what they are trying to say is that the intake plumbing, exhaust and cam are different on the GTO, the F-Bodys, and on the Vettes. However, the difference is neglible, not enough to cry about. Simple bolt-ons on any of the three will make them equal. But Vettes are marketed as having higher hp figures to sell them as the ultimate GM sports car. Hope this clears things up.

They have a different cam than a "regular" LS1 which makes more torque. This is helpful with the GTO's extra weight. The GTO also has real dual exhaust and is easily supercharged.

The C6 is a whole different animal from the GTO. I was referring to the GTO in the post above. The GTO is supposedly going to get the Z06 drivetrain for an upcoming model..."Judge" maybe?

Which has more power? Who knows? GM likes to play with numbers, so you can never be sure. We'll just have to get one on a dyno. If 350 is right, then it's about the same as an fbody (after adjusting for GM lying factor), but who knows if their numbers for the GTO are accurate either. Let the dyno see.

Hmmm. Holden was the ones who released the statement about a different cam, but I guess that could have changed before the production run. Most auto GTOs ave been dynoing in the 290s, so right in line with a LS1 F-body after taking into account the parasitic losses of the IRS...
