Ya there is a way. I asked this a while back when I was trying to figure out how to build a cheep stroker motor. I don't remember what piston is used if it is the stock or the UT2 though. I do know you have to use the predator rod and flywheel with it. Maybe one of the experienced builders will chime in. I don't know if there is any clearance issues with the swap as far as piston skirt hitting crank or something. If your going to remove the governor and get a billet rod and flywheel this might be worth it but if your just getting stock parts and keeping the governor I would just get a stock crank. I think I have seen them as cheep at $25. Are you wanting the 3/4 for a torque converter or just looking at getting a better clutch?
