Corrected Horsepower Factors > 340 ~ 360 ~ 383 ~ 400 ~ 426-S ~ 440

I thought that the H.P. 383 in the Super Bee and the Road Runner would have been good for at least 10 horses over the A-Body with it's restrictive exhaust manifolds.......
How about torque figures for the same engines?
Is this the N.H.R.A. factoring?
If so, when?
Also, at what R.P.M. were these figures attained?
How about figures for the 426 Hemi in all of it's production years?
Great post, BTW!
