Yes, I just detailed 68 and 69 ( as an example ) dealer datasheet specs and compared the info between chargers and superbees, and states Chargers got the standard camshaft and superbees got the hight lift ones, along with the diff springs of course

Never thought a 383 magnum charger ( and I guess coronets and Belvederes with supercomandos ) engine got standard camshafts! I always thought all BB magnums got same performance camshafts and sorings, so the same than 440 mkaing the "Magnum" name more standard to all BB meaning same inner parts for everyone. And superbees/RR got a even "higher step" one.

What are the difference between the standard and the "high lifft" camshafts then ?

I guess the first one of the purpleshaft cams is to the 440s and superbees/RR 383s then

Wondering now about the 400 magnums camshafts too
