I made a road trip upcountry last night and got 3 38mm Mikunis from a snowmobile salvage yard. My next magical trick is to science out mounting details. I'm thinking of making a header plate, and using longer studs so that the intake could bolt up to the header- that way i could use the Mikuni Triple Carb set, or the Fish individual carb. Marty- is the crank throw spacing 120 deg for the 230/250 Dodge Flathead?
