I tried this calculator instead, considered to be very accurate: http://www.smokemup.com/auto_math/hp_mph.php
I used a weight of 3820 lbs (1640 kg Monaro / 0.453 = 3620, plus 200 lb driver), a trap speed of 110mph which the thread claims is shown on some PMD literature, and a parasitic loss of 15%. The estimated crank HP is 406.1 and the estimated RWHP is 345.2. I think that's much more in line with a subtly underrated "340HP" LS1. 340 is given out because it's just under the current LS1 'Vette. Typical.

For GM to save money they can just put in LS1 right from 2002 F-Bodies and make the 345-360 hp they're claiming.

Even with the 345hp of the LS1 it won't be a threat to the vette. The GTO weighs like 400 lbs more, and with the same hp and the GTO not being as aerodynamic it's no threat to the Corvette.
The f-bodies were different, they weigh about 200lbs more than the Vette and have a live axle instead of IRS which means some f-bodies were handing the Corvette it's A$$.
So for the Corvette owners not to get pissed off GM underrated the F-Bodies.
I expect the GTO to make 290-300rwhp to the rear wheels like any regular Corvette's LS1 does.
If the GTO was making 390hp at the crank, it must have a LS6 in there and GM is not going to have the LS6 in there unless they told us.
GTO won't be under-rated.

Did you miss my post above or are you just shooting in the dark? Someone saw a piece of Pontiac documentation on the new GTO saying it has a 1/4 mile speed of 110mph. Having the 1/4 mile speed and the weight, you can estimate RWHP and crank HP. People have done just that. My post above includes links and numbers. IF this 110mph trap speed is real, and that is the big IF, then the GTO is pushing over 400HP at the crank and about 345HP at the ground. Read at my post above and follow the links, that's all I can say.

I don't think anyone who will do actually speed testing on the GTO told the people who wrote that document.
If the GTO is going to get a 110mph trap speed it would be doing the quarter in high 12's which already disputes the high 13's times Pontiac has said.
The only way the GTO would ever get those times is with a LS6.
Somebody at Pontiac screwed up.

Why would they under-rate the GTO?

Maybe GM has a policy of underrating all their V8 RWD performance cars, to keep the buyers happy. Anything wrong with that? 
As for this LS6 stuff... there's getting to be fewer and fewer distinctions between an LS1 and an LS6. My 2002 Trans Am came from the factory with an LS6 intake and MAF. I predict that when GTO buyers finally dyno their cars, they will again be delighted, just like FBody and Corvette buyers have!
