But the bright side of "the maths" is that the extra aerodynamic loads of running a vintage shoebox at 200 m.p.h. are likely only in the neighborhood of ~ 200-250 h.p., (virtually all of which are in the last second or so of a high six-second pass) so there's arguably not that much to be gained with a swoopy late model body . . .
Power-to-weight, on the other hand, affects the entire run. 3,800 lbs theoretically takes ~ 2,500 h.p. to accelerate to over 200 m.p.h.
The same power in a 2,600 lb car (excluding aerodynamic effects) is theoretically around the 230s. Thus, even with the extra aerodynamic loads, if all the other things go well, solid sixes are quite possible.
Of course, theory and equations have never won a single drag race)
