CrazyJesster,
I would go with the next one up from the one you asked about.
This one is only a little more money, and it
will make a difference. The point of a "loose" converter is to allow the engine to quickly/easily get up to the RPM range where it makes its power. You originally stated that this cam was in the 2000-6000 range. It also removes some of the drag/load from the engine while it at idle. This makes it idle more "freely" like it is in neutral rather than like it is dragging a trailer.
Of course this is another one of those traps where, "more is better" comes into play. Don't fall for that either. If the converter is too loose, you end up with a lot of extra heat and fuel mileage waste from the constant slipping.
You really don't want to spend $99 on a converter that is too close to "stock" when another $30 or so will get you where you need to be. Remember, this is a truck, it is heavier than a car, which most of this stuff is intended for...
