I dont have the 03 anymore
I have a NNBS 07 sierra with 38s and 4.88 gears.

Im wanting to put a cam in there thatll give me some low end torque. I dont really care about high end power at all but I dont want it to be non existent.

What cam would you guys recommend? And what specs should they be around?

Thanks

 

I'd look at thunder racings old man can

 

212/218

 

Ill look at that right now

Is that all I need to know when looking for one?

Whatelse other than the cam will I need?

 

you are going to need springs and pushrods also

 

Call a sponsor and get one custom ground that will match your truck and what you want it to do perfectly. Texas speed ground me one for my 6.0 that is perfect for how I use the truck. You may want to give up the cam route though what you need is cubic inches.

 

More cubic inches huh?

I'm seeing alot of NNBS 5.3s with cam, headers and tune putting down 350rwhp+

Thats plenty for me. Hell ill be happy with a 30/30 gain over where Im at right now

 

Torque makes you go.

 

This is what compcams recommended for me

Opinons please?

Every little bit helps. Thats their 5.3 "truck" cam a good off the shelf grind. You could always go a tad bigger with a custom grind but it will help you in various spots in the rpm band.
