I run a comp cam in my truck and I love it. If you call their tech line they can help you pick a cam for your truck that will work with your mods.

if i may make a suggestion, ditch the 3.73 gears. the truck will drop on its face horribly. i ran with the 3.73 gears in mine for almost 2 years, then went to a 4.56 which made it better but didnt fix the problem. i ended up going with the 4.88 gears and love them. now i know your gonna be makin more power than i am, but i would step up to atleast a 4.56 gear. right now with the 4.88's im runnin just a hair over 2000rpms at 80mph in 6th gear with 32" tall tires mounted on 08 tahoe 20's. with the 4.56 i was runnin between 1700 and 1800rpms in 6th at 80mph. check my vids and if you look at the older vids youll see how the truck bogs at take off. i have only been runnin the 4.88's for a couple of months. if you have any questions bout the t56 swap or setup let me know.

thanks for the info on the gears, that was going to be my next thing due to i have pretty much two of everything , two rear ends , trans, engines, foose wheels, etc, i had another RST that was stolen and recovered most of it except complete cab and interior, so my intentions is to get a rear end done that i can swap easy.

well the thing i ran into was the the trans imput shaft splines were hitting the crank baring before trans would mount flush onto the housing. so I ended up using a spacer like if it was a sbc.. it seemed to mount correctly but truck is still up on the air ( waiting for cam) so i'll see.
hey red04 is that center console from 99- 05 tahoe,, that looks damm good.

yeah im keeping the 4.8 just because i got two of them. why go buy a 6.0 , at least for now

hey trever how much boost r u pushing with that 3.2 pulley, and is that water/meth injection safe with the magna. what i mean is the injection mix goes through the radix screws ( roots) and barings could it damage in the long run , corrosion? because im thinking of getting a snow performance stage 3 , some time later.

626 HP , damm that is good stuff

im about to do the t56 swap as well. does everyone have to use this spacer? or was urs one of those cases where you just had to. im doing almost the same setup as yours only im going to try a huge cam and some ported heads along with spray until i can find me a charger to throw on as well. what other parts did you need for the swap? I know ls1 type clutch, driveshaft is different, sensors, and the shifter comes way back further so you lose the jumpseat.
