I need suggestions on what to do about the radiator fan. I have a 360 AMC with stock type radiator and flex fan. I think I should have a shroud, it starts to run hot when off road. Or should I get electric fan(s)? Might be nice to be able to turn them off for water. What has every one else done?
I like the elec. pullers with a shroud, but a shroud will help your engine fan alot, just make sure the shroud covers the whole core
(or as close as possible)...I use cowl weatherstrip (junkyard) against the core or tanks to seal the edges so all air goes thru the core, make the shroud extend to the middle of the blades for best performance, and leave a small drain hole at the bottom. leave room for a little flexing without the blades hitting the shroud 1 1/2" or so all around.
