Torque/tow cam gurus...
Short N sweet:
gmc sierra denali / 6.2 / 6l90 / AWD
•dod/vvt making odd noises already lost 1 engine due to this.
•dod delete kit on the way
•might as well take advantage of this & cam the 6.2
• I DO TOW-
•BIG ques: “i need a cam, that capable of towing”
• i dont mind going fbo’s/ torque converter/ custom tune.
•just looking for feedback on similiar applicasion’s or pointing me in right direction to the right guy, dont mind a custom grind.

3:42’sConverter will be changed to match the cam.Shift points will be match via custom tune to match the torque curve.

If you do upgrade the converter I would want to go to larger diameter unit that is still fairly tight. If the budget allows a 265mm billet unit would be best.
I will also echo that not much can beat the stock cam from idle to 2000.
218/228 114+3 would be a healthy cam for mid range power with plenty of part throttle torque. It would still pull to 6300 or so with the L92 heads despite its "short" intake duration. Drop a gear or 2 on the highway and this thing will make a ton of torque at 3k-4k to help you carry the load up hills without spinning the hell out of it. No need to go crazy on lift with a cam like that. .595" intake and .587" exhaust. The LS3 style heads have such large valves that they appreciate lift more than a cathedral, but being a driver and tow vehicle I'm more concerned with longevity and stability of valvetrain parts than whatever minimal power more lift would get you.

3.42 gears is a PROBLEM that should be FIXED, before you entertain any kind of cam.
Consider any kind of towing, you will have great benefit from 4.10, 4.30 or lower gearing.
Longer duration cam timing would be a step backward for you, with current gearing.
