Sure, a given SBC in a Corvette, which presents less frontal area, more efficient aerodynamics, and has better weight distribution because of engine setback, may perform better than that same engine in a Chevelle hardtop....... but the fact is, the combinations are endless, and trying to level the playing field between the myriad combinations using this method is a task that would never be finished, and in the meantime creates more problems than it solves.






Bill, Seems you are arguing for, and against ,in the same paragraph

Fact is, there are big differences in the index vs. weight, between the the middle classes and the lower ones. Powerglide vs 4 speed etc.
NHRA has gotten better about doing this since the early days of the AHFS ( The Billy Lynn rule...factoring 2 dr 79 Malibu's and not the 2 dr Olds Cutlass and Pontiac Le Mans, which essentially is the same car)
Now atleast they combine the 305 Camaros with the Firebirds and vice versa, as they should be.
It hast to be done correctly by someone who knows what he's looking at . You can't just all of a sudden combine 350 Novas with Camaros because a guy speaks out against NHRA.
Nothing wrong with factoring individual combos , if done correctly.
