Super73 not a word

I have the new trans in getting the controller hooked up and the rest of the new mods.
Trans is a fully built unit with 3900 stall convertor on the on the engine with T brake it may flash a bit higher with the NOS on the t brake release and hit will have to see. I did upgrade the rear end to a moser 9inch 35 spline wavetrac etc last year at this point I am going to leave the 3.73 gear and run either the Mickey ET 295/45/17 or the 275/50/17 M&H have not made that choice yet either way they are both 28 inchs tall.
