Not saying longer strokes dont work, do get me wrong. This is just my opinion and what I have seen.

Some myths get repeated, some get rejected as wrong, if your talking about similar prepared street and strip motors with the same compression carb size, cam, heads, exhaust, tune up, chassis, tires and so on in the same car with all the same parts a 4.250 stroke 400 or 440 block will outrun a 3.91 stroke every day of the year twocents
Been there done that whiney
The only combo stroke I haven't used yet for a good drag race motor is 4.00 stroke with a 4.500 bore or so, maybe soon luck
Torque moves the mass, not HP work
