228/232 .600 lift 112 lsa Texas speed cam idle for you. This is open headers.

 

Same cam with true duals hooked up.

 

Op about the best thing you could do is to just do a few bolt ons and put some 4.56s in a 6.0 2500hd truck. Especially if you're running larger tires.

Headers with td/x , ported tb and intake or change them to 90mm stuff, good valve springs and a set of 1.9 roller rockers, find or build a cai that don't have a 90* turn before the tb. Electric fans and a ewp would cool it good before truck pull rounds. Those mods with 4.56 gears would thrash a average h/c truck that overlooked those mods.

 

Definitely agree with gears. What size tire you run? I like 4.56s with 33 or smaller. I loved my 4.88s and 35s (actually measured 34).

 

Yea 4.88 be even gooder.

 

Old dude told me one time. Don't fear the gear and let some rpm do it's job.... Wise old fella..
