My 48 IDA webers from Jim Inglese. Jim had to custom make the 34 mm chokes for the 260 c.i. size. Jim supplied the complete Intake set up.
Valley Head Service did the porting and installed the larger valves.
Bullet Racing Cams made the roller camshaft- intake lift .3283 duration @ .50 223, Exhaust lift .3283, duration 227 lobe seperation is 110, Jim said that the lobe seperation will work fine. I hope that I won't have blow back into the carbs. Maybe 112-114 seperation would work better.
