Quote: I understand that the MP grinds are old tech but its proven technology that works. My dad is running what I think is the comp cam XE268, it is a .540 lift cam with 280 duration in his 67' Dart GTS that has a built 440.
I think the XE268H Comp Cam would be a good choice for your 383 truth be told.
Don't get me wrong, I really like the MP 235 camshaft (old version 484) and have ran it it dozens of engines, I'm one of the few guys who really likes it probably but I really think it's going to be more cam than you think in a 383.
I'm building a 9.35 to 1 compression 440 right now and almost went with the 484, but I ended up going with a Comp Cam 270H grind. Probably a bit on the mild side but I want a very drivable car, and I have 446ci, AC and 2.88 gears with 26" tall tires...
I've never tried the newer MP 484 cam, I assume it has a wider LSA or?
