What is the worst that could happen with too much stall?. Will I burn the tranny up?. Will it constantly slip at low speeds?. I was looking at a TCI Streetfighter. I'm sure I would be better suited to the breakaway model but after I add heads and "maybe" a bigger cam. My power ban is now between 3000 and 3500 with my XE262.

I don't think you'd enjoy the car with a 3000 stall with that cam. That cam makes loads of power at 2000 or 2500, which is where it should probably stall. With my 302* cam, I have a 3800 stall. If you do decide to get a 3000+ stall, do yourself a favor and spend the extra bucks for a 9.5" converter. They make less heat and drive nicely.

Yes, you could burn up your tranny with too much stall...but you can do that with any converter if you don't have the proper cooling features.

Before you get a converter, you need to plan what you want to do in the future. How big of a cam do you want to go? What gears do you have? How will you use the car?

Thanks for the info Matt. I'm fairly certain the truck has 3:73's. I was thinking maybe XE268. I thought the smaller diameter made More heat.

Ask the people who use ATI how they like their converter. You'll get a much different Opinion.

If you guys are looking to stall speed needs in the 3500-3800 or so area, one trick will help....most of the 10" street/strip converters use a negative fin angle along with a machined stator to achieve the 3500-3800 area of stall speed. The 9.5" street/strip converters use the same combo, but are typically 4K+ for stall speed. If you still need that 3500 or so, you should possibly look at a 9.5" converter in some situations. Why? Well, I have had quite a few of them done with a more positive fin angle, and even a more agressive stator. Thus, it is easy to have a 9.5" converter that has the stall speed in the area of a 10", yet is far more efficient due to the fin angle change, with a more agressive hit with a stator that provides increased torque multiplication. And, they are only $20 more for the BTE 9.5" vs. the BTE 10". It is pretty easy to build one that is at the 3500 area, and costs no more to have one done this way. That said, I do not think that you need that much stall speed with your combo. The normal 10" would be fine IMO, and you could do the same with it, and have the fin angle tightened up a bit to pull down stall speed and gain efficiency as well. The key is to have the stall speed right at the torque peak for the best performance, and just below it for a more mild usage.

I have a "tight" 9.5" Precision Industries converter in my daily driver. Drives like a stocker around town, but gave me 0.3 sec in the 1/4 mile. They are more money, but worth it, IMO.
