magnum engines used a bushing that pressed into the torque converter register flange in the crank for factory manual setups, and a roller bearing pressed inside of that. P4876056 is the mopar number. now with your A833 Id highly recommend having a machinist make an oilite bronze bushing to replace the roller bearing (the OE pilot bushing is a smaller OD than the roller bearing in the adapter block) as the input shaft of your trans isnt hardened (most modern 5 speeds are) and that bearing will eventually munch itself, and the shaft. OR have the snout hardened, and run the roller. Ive found in the 2 big block swaps ive done in both my trucks, the crank was drilled for a pilot bushing, but wasnt reamed to size. this was a 65 and a 68 361 and 383. I went with the custom bushing in the adapter housing route in both. If it were me, id go this route. It makes life so much easier.
