Launching!
11 turns with the Comp 7702-1 Checker would put you at 7.350", not 7.400".
Each turn is equal to 0.050"
0.050" x 11 = .55
.55 + 6.800" = 7.350"
7.350" + Desired Preload on Lifters = 7.xxx
So you should be using a 7.400" or 7.425" Pushrod. If using LS7 Lifters, 0.075" preload would be about ideal, which would be 7.425" Pushrods.

regardless they recommended it haha, I was initially looking at 224r but that was definitely to big. The 220 will be just fine for a little street truck, should bring the power in pretty quick and keep a relatively consistent power curve, and yeah definitely a lot of overlap in a 5.3 but from what I have been told by them is it is a pretty mild cam for a 6.0. But I have no idea, I know how to put them in haven't figured out how determine what will work best yet

Yeah I have a BTr stage 3 in my 2500hd and love it, we may end up switching the cam later on, the plans for this truck as of right now are up in the air. But we are going to try the 220r with the lower LSA and see where and how aggressive the power comes in and go from there. Shouldn’t be to ridiculous of a cam, definitely going to sound absurd but I have talked to a couple people with the exact cam in a 4.8 and they love it. Only one way to find out. The truck should be started by now but TSP keeps sending me the wrong push rod lengths and unfortunately I can not find a speed shop in Mass that stocks different lengths.
