Slant/833od clutch options

Hey guys, i recently put an a833od from an 85 d150 into my 73 swinger behind my 225. What performance cluch options are out there that will work? I believe its a 10 inch clutch, can i get a 10.5 or an 11 inch cluch in there? Ive been looking at the centerforce clutches because i intend to boost the old 225 in the near future. Any help would be appreciated!!:burnout:
