My drivetrain is significantly different than yours. But I went with a 3400-3600 stall speed. The point is, this seemed a little much, since it's so much more than normal cruising speed. But I talked with a few experts, and they all agreed that was about right.

When cold, it's a little tight. But once it warms up it works really well.

I installed a Circle-D triple disc, billet converter. Probably much stronger than I'll ever need. But it's one part I'll never have to worry about.
