I'm in the market for a new clutch for my 84 Ford 460 with a t19 4spd manual. I plan to run a splitter box infront of my trans but that doesn't have an impact here I don't believe. Anyway, I want the biggest and best clutch that I can possibly buy? Also I noted that there are several input diamaters and disk sizes listed. I'm thinking a center force dual friction clutch of the 12 inch flavor outta do me right.
