Spring for a good one with that 22" radiator, i've got a 16" perma cool on a 3 core 22" rad cooling a warmed over 318 and it still run's about 195 with with a 180 stat. I've heard Spal fans are the way to go but i'm sure there are other setups that will work. Oh it runs just fine with my stock alt. wired to the starter relay with an inline fuse and adj thermostat.
