You just need to convert your carbs, and get a pingel petcock. I had a fried that ran 4.5's on a stock port 350 on alky. You can convert them yourself or have a builder do it for you. It probably would be a good idea to set your bike up to do whatever you want (porting, chassis mods, bigger carbs, blah blah blah blah) and convert it to alky after.
