Isn't that a race only piece?

i hope not, ive seen various aftermarket intake manis for our trucks. i know the stock ones flow good but they are so ******** ugly

Save your money and put a blower on there!

Or the new FAST truck intake.....I think the blower before the cam.

Highrise intakes are not good for trucks. Highrise intakes are for High RPM engines where the power is in the 6000+ rpms. You will be slower off the line than a smart car trying to move the weight of a truck.

makes sense, looks like its just going to be a cam in tune then!

TBSS intake and LS2 throttle body

No need unless you're pushing some boost. A cam and blower is better bang for the buck. More on a budget? just do a cam.

I have headers, CAI, exhaust, underdrive pulley, and a cam and I picked up about 100 wheel HP. All the mods cost round $2K for everything and I did the installs myself. Oh and a good tune.

Waste without a cam. Wont work on his 01 unless he is a rare one with drive by wire.

its cable does an underdrive pulley make a difference? my dad has a 97 yukon with one but thats a 350, didnt know if they made a difference on ours

A little more off the line power but not that much. It's also a little less rotating mass. For the price of the underdrive pulley you can swap to e-fans which would be better and add about the same amount of torque.

Jenn it works on my 2001 but I am drive by wire also and had to get the adpator from Texas Speed. I also have heads and cam too

He can run a cable 90mm TB. Holley, Edelbrock, Nick Williams, all make TBs.

What cam you going with? Stall?

Go with a TBSS/NNBS intake. Cheaper and better. You will need to modify your rails, or use a 97/98 Vette fuel filter and the newer rails, and make spacers to use your injectors, or get harness adapters and run the newer ones.
