To keep this on-topic, I did almost ALL the part gathering for dropping my K321 into my #72 until I couldn't find one of the forged Alcoa rods so then the whole thing SAT. Three years later I found a rod AND a K361 cam. Within about 3 months the engine was together, straight pipe made, custom 3 gal. fuel tank made, many other new parts like HD MWSC clutch, pressure plates & drive shaft installed, new steering gearbox, different rear axle carriers with needle bearings & new seals & gaskets installed. Assembly goes quick when the right parts finally come together. I even sent an e-mail to Alcoa asking about buying raw forgings from them for those rods. Of course I didn't get an answer!
