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.
4L80E Conversion Crossmember 00-06 GM Truck (4WD)
Available in Satin Black or Red *NOTE* '99 and some early '00 trucks utilized a crossmember with offset frame mounts. This crossmember will not fit trucks equipped with these offset mount crossmembers. Speed Engineering suspension and chassis components are designed and tested with the purpose...

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.4L80E Conversion Crossmember 00-06 GM Truck (4WD)

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.

I didn't heavily modify my crossmember for my 4L80e swap. The mount needs to be moved about 3"~4" back. I took a 3/8" thick piece of metal and bolted it down to the crossmember. Then I drilled new holes in the plate about 3"~4" back for the mount.
Yeah there's performance there to be had but it'll also drive kinda spongy and terrible IME. I would gladly give up some performance to not feel like my trans is always slipping.

You sound like someone who hasn’t experienced a nice converter. Buy something of quality with a good tuner and it’ll drive like stock in regular driving.
I have known many stalled auto guys in my years of being into cars and most all of them buy good parts and their cars run good because of it. The last one I was in was a 6.0 swapped rcsb z71 with an 80e and a PTC billet triple disk. You are probably on to something in regards to tuning because that wasn't tuned the greatest before it was taken back apart but even then it felt meh to me. I would gladly reconsider once I have experienced a properly set up thing but I dunno, just from my limited knowledge of how they work and how they are "supposed" to drive, I think it may just not be for me.
