Before you get to ordering parts you might want to see if an alluminum rod will swing with that big stroke ! Another thing to check is cam to rod clearance ! On my motor with a 3.625 stroke and a large base circle cam I had to cam clearance the rods and that is with a 2.0 rod journal ! It might be a good idea to talk to an engine builder that puts these combo's together before you spend a lot of money on parts ! Are you going to run a blower ?
