Ok Guys I finally bought an LS6 Cam and springs from an 04 CTS-V. I would like to know if I will need a TBTC? I have 29.5" tall tires and plan on in the future going with 4.11 Gears. I would also like to know if I need to change Push rods to the longer ones? I have heard different things and would like everyone's opinion. I also emailed HP Tuners to see which tuner I needed...I haven't got a response back yet. Do I buy the VCM Suite ($499)? I want to tune my Sierra (soon to be mods) and my 03 Denali XL(stock)

I should get all my go fast goodies next week, and install them the week after.
Any help would be greatly appreciated.

 

in my 5.3, i kept the same pushrods, but put the ls6cam with yellow valve springs.

1sik02 Your 6L sounds good. Do you remember what you torqued the rocker arms to? I looked up the torque on an LS1tech article that showed 22 lbft.

 

Read the same earlier today. Check a Haynes Manual. Should be the same.

 

I just bought the VCM Suite from HP Tuners, Hopefully I can figure the tune after I get it. I cant wait!

 

Can anyone point me in the direction of the NOOB HP Tuner section somewhere? I have about a week before the Tuner gets here and I would like to be able to hit the ground running.

 

The forum on hptuners.com should have something... download tunes in their repository for looking at general settings.

 

i dont know what it was all torqued too, my friend was a mechanic at a chevy dealership, done the swap in 4 hours, cranked right up. been fine ever since, except now i have a 5.3 lol

 

Took both trucks to the track tonight. for the Sierra, the best out of three runs was a 17.8 spinning the peg leg 1/4 the way down the track. I cant wait for the go fast goodies to come. Hopefully if all goes well, I should have it done in two weeks!

My Stock 03 Denali XL ran a consistent 16.4...not bad for as heavy as it is.

 

Update...I was just about to stab the LS6 cam into the block and decided to take a break. I checked my PM's and got a reply back from a guy that I had emailed about a 212/218... Needless to say, the LS6 cam is not in the truck and I have to wait for about another week to put in my 212/218! My poor truck is all torn apart and waiting for it's heart transplant!

I am debating wether to install the LS6 cam in the denali or just sell it?
