clutch fan too close for 3 row radiator on 360 engine
My 360 stock engine in the 67 Barracuda was running hot with at 2 core aluminum radiator so I decided to go with a 3 core Champion aluminum unit. Problem now is that the 7 blade fan with clutch won't fit, it's only got about 1/8" clearance. Is there another clutch available that's shorter? I'll need a part number too.
Sounds like they sold you the wrong radiator. I have a 4 row high efficiency US Radiator and have plenty of room. Probably too much. I need to make a custom shroud too as this is a 22" '68 a-body with a 5.9 Magnum in it. The hose is on the wrong side on one of the tanks. I forget which one now.
Give Champion a call, explain your problem, send them a picture and request they correct the issue on your application.
Or, is there any way to trim the mounting flanges off the radiator, make your own that position the radiator deeper into the front radiator opening?
I don't have the part number for the shorter fan or water pump shaft mounting plate, sorry, but I have heard there are shorter versions. You may also be able to gain some extra clearance by machining a bit off both mounting surfaces of the water pump pulley face and the clutch fan mounting surface. Just don't over do and you won't significantly reduce either's strength.
Are you running a shroud? If not, you should make one or buy one from the radiator manufacturer. It makes a HUGE difference. Just seal it up good and make sure it doesn't leak around the edges when mounted. I will be adding one when I install the new motor, mostly because I am going to put an A/C condenser and I already have a trans cooler in front of it.
BTW: it has never run hot even when being flogged at Willow Springs in 100 degree weather, or while sitting in LA traffic during Spring Fling. I love US Radiator!!!
