Cam swap and tune: Tips and info needed


Recommended Posts

Hi fellas,

I need some tips, info, and know how for my 2006 Sierra Denali build. I'm finally comfortable with my income that I'm going to start my build. I want to do a cam swap and get a tune. The cam that I want to use in made to spec for Lingenfelter by Comp. The cam specs are:

LINGENFELTER GT11 HYD ROLLER CAMSHAFT 350-383-427 LS1 LS2 LS3 LS6 215/231 .631/.644 118.0 CL

The actual webpage can be viewed at:

http://www.lingenfelter.com/mm5/merchant.mvc?Screen=PROD&Store_Code=LPE&Product_Code=L210065297&Category_Code=C31#.USIlKo4TtaU

 

Heres my deal. The page for the cam says that springs and retainers are a must for this cam. That is cool. Should I change the pushrods out for some chromoly ones too? Does anyone think this cam will be too aggressive to be daily driven? What I'm going for is a came that sounds nice and lopey and sounds mean and aggressive but still keeps the daily drivability while not affecting my MPG much.

 

Lingenfelter also offers another cam with specs that are:

 

Cam Number Duration @ .050 Valve Lift Rocker Arm Centerline LS1-GT2-3 207 / 220 .571" / .578" 1.7 ratio 118.5

What are going to be the differences in sound and drivability between the two?

 

I plan to get Long Engine Works in Elkton Md to do the swap for me. He is great and been around a long time. He did the milling for my block when I did a complete engine rebuild of my GMC Syclone.

 

So besides what I have stated above, I'm obviously going to need a tune after the swap. I'm not sure, but I don't think Longs can tune it. It there any Dyno shops or performance shops in the Maryland, Delaware, Pennsylvania, New Jersey, Virginia area that you would recommend or should I just send my PCM out? Thanks for all the help in advance guys.

That GT11 has some pretty good lift. Springs, retainers and pushrods are a must. Why not go with something with a little less lift (like the GT2-3) to make it a bit easier on your valve train and make up for it with a little extra duration (like the GT11)
