Watch some Richard holdener videos, he’s recently done cam testing for exactly what people here want, more torque.
I think the sloppy stage 2 cam still seems like the best bang for the buck.

I highly recommend a low lift 212/218 112lsa cam, it will sound good make more power everywhere, and not sacrifice anywhere either. The sloppy stg2 is a little aggressive for a 5.3 IMO. Summit has some good low lift truck cams as well and the savings could help pay for valvetrain upgrades.

I will have to look into that then. I definitely want them to modify my crossmember, as I don't trust myself THAT much with a welder. Thank you for your input!


This is who I'll go through for my crossmember but there are a few others online that make them as well.

Oh wow I really like this site! The FAQ section is absolutely amazing! I'm already window shopping a TBSS intake as we speak.... That looks like a perfect addition to my upgrade list, but do you think with the TBSS intake manifold and https://www.glennsautoperformance.c...cam-dynamics-nsr-truck-cam-low-lift-cd13001-1 cam I will need a new converter with a different stall? Thats a decent amount of torque gain over stock with just those two parts alone from my research and reading.

I don’t think so. I’d try to avoid a new converter too but my only experience has been in a truck that wasn’t really well tuned for it and it drove pretty terrible. Not sure if tuning would have changed that but it’s definitely turned me off from the idea.

You’re leaving performance on the table without a converter in an auto. A tune certainly makes or breaks how a high stall drives.
