4.30 gears,28 tires,126 mph???

Thanks Moper,I dont know the efficiency of my converter.Had it built for first motor by continental and told them I wanted a efficient converter and wanted a 3500 stall,26 tires still street driven.New motor with same converter,,,,now race only,more hp stalls at about 4000.with 28 tires.I never had been to a drag strip till 3 years ago so I am a kinda a newbee but I read alot and listen,,,then make my own decisions.My gut feelings still say 4.30s.I cant figure out how to do the efficiency factor..Guzzi Mark
