Testing the waters of going 318 to 383 in my '67 Fury III. Trying to plan things I wouldn't think about. What are some things I would need to change or headaches that would arise? I would need: Big block 727 Different transmission mount New motor mounts Trans kickdown linkage Throttle linkage/cable Tranmission cooler lines The radiator, I need to look at the bottom outlets. Is the driveshaft the same from the 318 727 to the 383 727? Can the same torsion bars be used? I need to look at my FSM when I get home but I can't remember if the 383's used 5 leafs or 6. That would stink if they used 6 because I just ordered new set of 5's thinking I would use my current 318. I am using Kahn's thread titled 318->383 swap as well. Thanks for the help.
