What would I have to do to add it to the pulley directly? I would worry a little about balance at that point. I will not being doing any towing of any kind with this, this vehicle will be nothing more than a daily driver.There are several options, cheapest is to add it directly to the, pulley. Second way is to use the Dodge option, pre 94 or later. Pre 94 put the fan centered up high or post 94 puts the fan lower and to the left, this also put the fan forward about a 1.5 inches. I'm using the post 94 Dodge fan setup. If you want to tow with your 4BT and run AC you should have a mechanial fan.
Last night I pulled a '64 Chevy longbed 2WD (5,000 lbs? with scrap in back) on my 1400 lb trailer behind my 5800 lb truck. I figure over 13K-14K lbs total. Up and down lots of hills, outside air temp about 40* F, for about 70 miles.I will not being doing any towing of any kind with this vehicle
I would second the fan(s) in front of the evaporator. I used to run electric fans for both the engine cooling and for the AC evaporator. The electric fan for the engine proved to be inadaquate here in Arizona even with out the AC, so I added the machinal engine fan, now it will bearly read above 185 F on the hotest condictions. I still use the AC pusher fan on the evaporator with the AC in town or wheeling, the engine doesn't get hot enough to trip the fan clutch to come on.Which is the reason I want a fan, I will be running A/C and I like my A/C VERY cold.
