I found out if you use the 1973-74 extreme fan clutch from the 454 it will work on 350s with the small 283-350 water pumps I use the 7 blade fan from the Dodge trucks or Cars that had the 340-360 to the 440 engines There a 15 1/2 inch 7 blade fan. this is the set up I use.

Plus the straight out Thermostat from 1964--68 Chevy small blocks If you use the Edelbrock Performer alum intake the best place for the Temp sending unit is on the right side of the intake you can't use the water outlet that points to the driver fender gets in the way. They sell all the parts at all the truck part places for are old trucks
