Are any of you guys running a Gear venders unit with a 3500 ish or even higher converter?. My 64' has 4.10 gears with a 29.5" rear tire and i'm toying with the idea of getting a Gear Venders but i'm not so it would work well with that high of a stall speed. I haven't bough either the converter or overdrive yet. G.v.'s website states that it's doable but i'm worried about heat build up.
