Awesome info guys thanks a lot. I didn't see in the posts about how thick the Ford fan is. I have about 4" max to work with but the way yall talk I should have no problems. It's just odd that a lot of these conversions people can fit factory fans with no prob. My buddys dad did it in a 81 square body with a 1st gen motor and radiator and had about 2" between fan and radiator. Don't quite make sense but anyhow to the junk yard I go!
