Your mixing apples and oranges. Go look at the torque numbers of the Buick. That is where it produced all its power. Also, the factory HP rating on it was known to be way underestimated. Bottom line, to get under the 5 second runs, you must have the HP in the 400's. It is simple math.
It may be simple math, however the bottom line is; many cars have done it and will continue to do it.
Sometimes math has to take a back seat to reality........and torque, something you understand - and some don't.
You mentioned torque and rightfully so, however the original poster stated you cannot produce sub-five second numbers with less than 380 horses, then adds that it will take more than 400 horses.
No mention of torque, so I AM comparing apples to apples. Even when the "real numbers" for the car were revealed, horsepower numbers were below 330 with toque numbers above 420.
And that's only one example, there are quite a few cars that have defied the math.
