Have all but finished a 49-3100. We have 255 75R16 tires on Sand blasted and epoxy coated rims. Rides fine. We got it with a 54 235 which had not been rebuilt, Rebuilt it 40 over, put in an 848 Head, Fenton Headers, all new rocker assembly and Weber 32/36 Carb from Tom Langdon. More than enough power.. Send me your email and I'll get you pictures--Bill
