Im running a custom hyd roller with 230 and 520/530 lft on a 110 cl, there is no shortage of tq off idle up to 5500.
When you change everything about the bottom end it changes what a cam does on the low end that it normally wouldn't in a shorter stroke motor
He might want to do something with the gearing though, and he has 3 diff cams there, and seems to be leaning to the other.
Remember, it's a truck it needs to pull and when you get hung up in clay, you want that high rpm power....
