Aw,,Bob,,,,, I was hoping you'd answer him on this. I've been kicking around the idea of doing one of these engines for a while, but am hesitant because I have 4:88s (Dana 60) and a 29 1/2 tall tire and worry that I would spin it too tight on the top end. Just curious I guess,, oh well, thanks anyway.

I'm guessing your running a glide, what rear gear ,how tall of a tire and your MPH. I'm wondering if my converter is going south...............
