Thought I would start another post about cooling a 500+ BB in an A body. Still not sure which way I'm going with the radiator,but as this point I could go A or B body down flow. I would like to cool this with a 440 source mechanical 40gal water pump and a flexi-lite 6 blade fan with a full rad. shroud. Can this be done or do you think it would be easier to cool with electric fans? Heres the fan.
