Now were talking!! I think the answer is going to be to get the car finished with the tranny I've got at present, see how it performs, and in the meantime I need to calculate the distances from using a toploader/tremec/B/H, and ensure the bracketry will accommodate all options to ease the changeover in the future, on the question of cooling, the heat factor does worry me slightly, there is a vast range of Tranny coolers available out there,what do others use ie make/capacity/setup, I'd be interested to know, thanks again for all your inputs.
