I should have put this in the previous post. Here's a gear calculator you can play with to figure out how it'll work together.

Just select your tranny, put in your gear ratio and tire diameter and go down to the bottom and it'll tell you your speeds at whatever rpms and mphs you want. Messing with it a bit it looks like you'll be getting 60 at 2400 rpm if you're running 8.25x20 tires (about 37") and a 6.33 rear end. If you''re using an OD tranny the low gears are what you want.

Thanks, I added that to my bookmarks, that will come in handy for a number of my projects. If you are right and it is on 2400RPM's @ 60, that might be a little high geared yet as peak torque on my 351W will be around 2800. That is a workable number though, I would try it in the truck and see how it was before changing it but I fear it would be constantly downshifting for every little rise in the road. I will probably get a higher stall converter which will help keep it in the power band and get it off the line a little easier and of course a very large tranny cooler!
