Sort of have to make a fairly quick decision on which would be best for an anticipated circuit race car project, someone wants to buy my LS. For the price of the LS I could get a good M113 with trans and more. The choice for a LS transmission would be a Ford 6R80, both would get aftermarket controllers. As usual I'll probably ignore any advice :wink: but you never know, someone here may have considered going down a similar problematic track.
