A friend from the Bronx with a 69' Bee, full interior, full metal jacket body, 500 ci. not sure of the Hydraulic cam profile though, but good enough to idle and drive around town in the heat and drive back and forth to Carlisle, Sh#tty 750 carb drenching the engine with raw gas, 323 rear cogs, drag radials and 8-3/4 rear with no traction, No Suspension mods at all, Trans with a mild shift kit and no other tricks, AC, power brakes,power steering, power windows with serpentine belt, no air scoop what so ever, 11.70's with me driving for him.
You need to address a suspension plan and a good tune along with a good fuel delivery system.
Should haul some mail.
Right convertor and other mods in the rotation devices will fetch you the 60' shots you deserve. Still a can of head scratch and misery.
