What is the correct fan to radiator clearance?

  1. Is the shroud the factory shroud for the car, rad engine combo?
  2. did the car, rad, engine combo originally come with a clutch?
My 67 273 did not come with a shroud and the fan is 1-2 inches from the stock rad. with a stock shroud the fan is about 1/2 in and 1/2 out.
Hi Dana67Dart. Factory shroud for 340 car and radiator engine combo. Can give you the numbers if you want. Car was originally /6 with clutch.
