Why the focus on torque ? It's the hp at the rear tires that matters say 35 mph = 3000 rpm and 65 mph = 5500 rpm and your making 250 hp at 35 mph and 425 hp at 65 mph isn't all that matters is a 273/318 or even 440 make similar hp numbers at those mph ? Obviously each will be geared different to do so, and yes a 425 hp 273 would a lot and at high rpms with very deep gearing but theoretically should pull the same ?
Or we just accept what we make between 35-65 mph some be faster others be slower?
