At the power level you are looking at you will need a Jerico DR4 or G-Force 101. 833 are the strongest factory 4spd ever made but they do have there limitations. Jericos and G-Forces are about $4500 to $5000 new. I picked up a jerico for $2000 used in great shape they are out there just keep looking. Now the rest of the bad news you will "need" a $2000 to $3000 slipper clutch ( Mcleod soft-loc, Advanced, Bonnifonte, or equivalent)or you will be breaking every part in the drive line( ask me how I know) and for get the drag radials they do not work on high powered stick cars, once they break loose they will not recover (the sudden snap of a gear change) call M/T or Hoosier they will tell you the same thing, bias ply are all that work.
