The Lincoln Mark8 fan comes with its own shroud. I dont much about a jeep fan. We have wiped out our yards up here of all fans from Lincoln Mark8's.
As far as running a fan all the time, its not good to do. An engine needs to have a particular operating range to run efficiently. I know a Vortec runs perfect at 150-175. If you run full time you will cool too fast and draw on your power source as well. I have it set to come on at 155 and will cool it down to 120 quickly. This is all a mechanical fan clutch does. The fan may turn all the time but its at a free spin until the clutch heats up to a certain degree and then grips the fan to pull more air.
