I've got a nnbs 2008 scsb sierra 5.3, i'm getting rid of the DoD, and I plan on going turbo over the winter, I see a lot of people have had luck with the zo6 cam in this setup, but now i'm second guessing myself. any input? I plan on going with the on3 turbo setup with a 70mm turbo and 4l80 with a 3200stall

 

if its factory manners youre after then I think you will be better off the an LS2 cam.

The LS6 cam will work, and it will pull harder up top, but you will sacrifice power down low up to the mid range for sure.

Basically even in a larger engine this cam makes OK power... and it carries it out forever!

I have a 6.0 with square port heads and the LS6 cam in my daily driver and peak tq is at about 5300 RPM. Thats pretty damn late.

 

Best cam for these trucks is one that makes good low to mid range power, especially when you're using a turbo. I would seriously look into the Stock48 Isky triple 12 cam. I bought mine with the intention of going turbo with it as its proven to make great power with boost.

NA with this cam in my 5.3, with a STOCK trans and STOCK exhaust, makes a little over 305hp/315tq.

 

well, i sent stock48 a pm, so we'll see what happens.

 

Thank's guys! Pm returned. Been having great luck with this cam in the 4.8-5.3 cars as well.

 

If your going boosted I would reccomend an ls9 cam

 

...no

 

I have a GT2-3 cam in my 5.3 and made 552 rwhp
