I was also told,a while back, that all 4bbl Big block engines in 2nd gen Chargers, were Magnum engines, no matter the color it is painted. Because it was Dodge's performance engine in its performance car, and all A/C car engines were blue,but in a Charger it was called a Magnum.

Again I do not know that to be a fact, I am not trying to argue with anyone, I am just saying what I was told years ago by some guys, I am just trying to educate myself on the matter.

I mean you can't even feel a 5 hp difference in a 330hp vs 335hp 383 anyway, and I think the HP and torque #'s are rated at same rpm on the motors.
