A-904 shift kit

@ 400 hp... street driven. maybe track when I get the itch, I live down the street from the local drag strip.... will have to do it. using the standard 4 clutch, not going to all that modifying and buying another clutch housing, , I have it all ready. any way, why standard steels? and not kolene? what's the deal on that? so if that is the case I can use a standard kit ( cheep) for soft parts, and spend the money on good shift kit and t/q-verter.. I will use red clutches if I find them with in reason, or stockers cold work, already have a custom external spin on filter kit, an deep pan, and add on cooler up front.
