mechanical fan

[dezerts10]

after a lot of thought and reading something PCI Scott posted i want to start looking for a mechanical fan for an ls1. everything i have seen has an electric fan. can you attach a fan to the crank pulley on an LS1?

Some large trucks have crank mounted fans, but won't that cause a ground clearance problem on a regular car or truck?

It should be doable, with care.

isnt the crank the usual place the fan is on like a 350? or am i confussed about the location?

i thought they were higher up, towards the intake manifold.

im drawing a blank i cant remeber where they are bolted to but is it possbile to have a ls1 with a mechanical fan and fan clutch?

Yes, they run off the water pump.

[dezerts10]

thanks Brian

Most gm small blocks run a mechanical fan off the water pump with a pulley behind the fan for power steering, alt, ac comp, etc. All belts or serpentine belt run back down to the crank pully.Most of the ones I know of are centered. If they are offset, adjust the fan shroud as needed..
