Quick question, does anyone know if the MP shortblock hyd. cam's (the pre mag 360 in particular) are "mopar grinds" or are they of the "chevy grind" kind. Thanks in advance.

The MP grinds were developed in the 1960s with trial and error and a bit of guesswork. Guess what? Modern computer designed cams are much better.

Have a look at Hughes new HEH series cams. They are even fatter than the older cams they were selling. More lift for less duration overall but the profile is almost square with the valve opening/closing very fast and staying open for longer at the higher lift levels.
