Hook up to 4-speed manual

You'll need a smallblock bellhousing, a 130 tooth "swap" flywheel, and a 10.5" clutch. The clutch and bellhousing can be standard smallblock parts, the flywheel is the only real unique piece, though I think they are fairly available. Depending on the Hemi you get, you might have to cut a section off the tip of the input shaft. I don't think the new Hemis were typically drilled out deep enough for the really long pilot shafts on the 833. You'll need a register style pilot bearing/bushing (bushing that fits in the larger diameter hole in the crank where a torque converter would pilot). Don't remember the part numbers off the top of my head for them, but they are easy to get parts store items.

Regarding cutting the input shaft, I just measured everything real good a few times and it worked out to be around 1/2"-3/4" that had to come off. A cutoff wheel gets the job done just fine, but it does take some time.
