Pick a cam for me

I really like the MP grind, too. I’m hoping the OP has been busy changing out and lets us know what he went with. Johnny Dart’s recommendation reminded me of another cam I've had experience with and would also play nicely with the wide step overdrive 4 speed. I’ve seen The Comp XE 262H work very well in heavy trucks with a wide ratio heavy duty four speed. I would have thought the 268 to be a little on the large side, but I’m not going to argue with results!
