I just checked out the 383 vs 383 test....they both made the same peak power and torque , although the Mopar made more power down low.
Kind of a silly test really, they should have done a 396 Chevy vs a 383 Mopar.
I believe that may have been, but peaks don't win races, broad torque curves do on the street esp. & the primary thing I wanted to draw attn. to was the short stroke Mopar
had more low-end, contrary to what some would expect.
