The point I am trying to make is that on paper if you point out one car making 372 RWHP and the other car making 455-461RWHP then automatically one would figure its an easy kill. But like I said, that doesn't take into account gearing or weight. If you don't think weight and gearing has anything to do with how fast your car is, then you need to read a bit more on some basic physics, und bone up a bit on your drag racing.
If you really want to prove me wrong, take your Viper to the drag strip and take off in 4th gear since gearing has no affect on acceleration anyway. You'll save the time of having to shift that car, and you should run an even better time, right???
Like I said before, look at 600 lbs at 8 lbs per HP. That means the Mustang need 75 more RWHP just to be even... 455-75=380, 461-75=386. My car made 372, like I said. From a roll I lost by around 1 - 1.5 lengths which you'd expect if you were racing identical cars and one was making 10-15 more RWPH.
As for the gearing, heres a little something for you to chew on. Here is the gearing of a standard M12 vs the M6
(2.97/2.07/1.43 vs 2.66/1.78/1.30)
M12
2.97*4.10=12.177
2.97*3.42=10.1574
M6
2.66*3.90=10.374
2.66*4.10=10.906
One of the guys I know with a regular C5 is having an issue right now. His car with an M6 and a 3.90 gear will only 60' a 1.50-1.52s normally he is @ 15psi launching at 6k+. Well, if you look at his gearing, he is basically no much off what my stock Z06 has with 3.42s. Now, you put 4.10s in the Z06 tranny together, you get really deep gears. That gets you out of the gate.
I don't drag race Vipers, but one of the considerations I would have on drag racing one of them is what RPM I want to go through the traps at. I'd set my rear gearing accordingly.
For instance, if I sprayed the car I am running now I would need to go up to a 3.90 or a 3.73 or I'd be out of motor around the 1000' mark.
As for 60' times, again let me try to clarify that for you. I am pretty well tuned into my car and what it does. I can feel wheelspin in the car, if you drag race acar, you can relate to what I am talking about. An ET Street or a slick can spin without blowing your run. Its not like a drag radial where if it spins your run is done.
Let me give you an example. In my stock Z06, I ran it with the Et Streets. I would launch @ 6600 RPM with 10 psi in the tires and dead hook. When I say dead hook, I mean when I unclutched the car, all it does it hit the tires and goes. But, the tires grip so well, and the car simply doesn't have enough gear or enough HP to use all that traction. So, the best ET I could turn like that was a 11.8. So, I started tuning the car to have some spin. This would allow the car to stay up in the powerband during a launch. I would jack the pressure up in my Et Streets to between 18-21 PSI. I would spin the tires out 20-30 feet and 60' a full tenth quicker than I did when the car was dead hooking, and my ET Dropped .2 to the 11.5-11.6 range.
Now, go out and read all the thread on folks who ran their cars on the same night @ HRP that I did. The track had just been resurfaced with new concrete to the 1/8 mile, and new asphalt to the second turn off. No one had run on the track, and it was still a very "green" surface. The right lane was hooking better than the left. Sure my car 60' ok, but you could still feel the car spin, and on one pass, the car moved to the right enough that I you could see it. As for the 60' times, I don't know that a Vette with an IRS can 60' much harder without starting to break the driveline. But, I have friends with much milder combos 60' even harder than me in F-Bodys. A friend has a relatively mild C2 cam, and a small stall with 3.23 gears in his car and has 60' a best of a 1.38. 1.38 is amazing, but its because his combo is completely dialed for that combination.
Take the time to watch the video of the car running, and give me your feedback then.
Again, I never claimed to run a 10.5 on 463RWHP. The car has been a best so far of a 10.82. My main competiton has run a 10.58 and a 10.59 on around 480RWHP
Here is the thread (with comments from John Myrick) about me running his new SRT-10 with my stock Z06 (ok, stock with the airbox lid off).

J-Rod listed his excuses so here's mine... I banged the rev limiter a few times myself. I was waiting for the cool little shift light to turn red. I soon found out that waiting for it to turn red was just a little too late. Luckily, I could hear him stuttering off his limiter too. Don't forget J-Rod's car is not stock. He convieniently forgets to mention the noticeable gain in rear wheel HP he gets from the "zip-tie" air box mod. I think he says it was worth 15 rwhp. Isn't that a car length? That's more than I got from my $700 titanium/carbon fiber super duper whatch-a-ma-call-it on my Z06. And I could say that my Z06 is still stock?
And before all you Z06 guys start thinking you can kick my butt, remember J-Rod's figured out how to make his car scoot down the track quite a bit faster than the average joe.
Oh and I almost forgot... I didn't even press the accelerator all the way to the floor. Yea, that's it. Not even full throttle. I didn't want to crumple the carpet, you know. Yea and my foot hurt or something... and a bug flew in my eye. Yea, that's it. A bug flew in my eye.
Perfect example of how much extra horsepower it takes to win a street race. Even with a little more than 70 more rear wheel horsepower, the Viper could not do much damage to the Z06.
Again, feel free to question me on any of it. I have nothing to hide, and I don't mind proving any of it on the street, or at the track...
