I have an 04 burban that I am looking to install a stage 4 btr truck cam and a high stall TC. I have a 40k trans cooler already, but would I be burning up the trans with a high stall TC and the cam? should I keep the stock TC to keep temps low? regear to 4.56s? I have 295/70/17 tires now, will be going with 35's when these wear out. I do not tow often, but I am not wanting to limit my abilities.

Regear. I wouldn't mess with the tranny unless you really are going to move the torque band up a lot higher.

So regear and stock stall? I plan to regear regardless, even if I don't do the cam.

If your stock gearing is 3.73, by just going to the larger tires 295, you are effective at 3.08 gearing. Going up to a 4.56, you will be back to effectively 3.73 without changing anything else.

Yea I get that about the effective ratios and all, I regear every vehicle I own anyway lol. But since btr recommends a TC on everything over stage 2 I wasn't sure. I know the high stall creates a lot more heat and that I am not a fan of

So what are you intending the truck for switching to a stage 4? Are you planning on doing stoplight drags?

If you are doing all that and swapping the high stall converter, the next weakest thing is going to be the transmission itself.

You should rethink your cam choice. It will be terrible for towing. Check out Vinci cams: http://www.vincihiperformance.com/camshaft...ls%20truck.html
