Well, I have a 99 NBS 5.3/4L60E. The motor has roughly 120,000 miles on it. It still runs smooth and strong. I have lift that accomodates 37" tires. I need some more power. I did re-gear my rear-end which helped alot. I have 4.56's in there and removed the G80.

I dont plan to every install any forced induction or nos. I want a nice decent Cam that will help turns those tires, gain some torque to tow, and maybe a little more gas mileage. A cam that is not to drastic, that can run on a stock tune, and no additional stall.

I have searched and I didnt find any people in my scenario with lifted trucks and oversized tires. Thanks guys.

 

Vinci 'Trucker' cam may be a good option or something in the 212/218 range...

 

What is the LSA? Does it run smoothly with stock tuning and stall?

 

yep. i was guna say to look into the trucker cam. it should idle smoothe with a stock converter. what kind of tune do you have right now?

 

It is a 115 LSA. It runs good on a stock stall but it would be best to get a tune if you want to do a cam to get idle and everything else set...
