No. I'm going to do it the next time I have the radiator out of Vixen. I have a five blade solid factory offset fan I'm going to put in place of the tiny 4 blade.
I didnt think it would matter a 4 blade or a 6 blade but just checking. it is a non ac car and it isnt a lot of ponies so I wouldnt think it would matter. Now if it was my 440 Duster with a lot of horsies, I would be concerned. I have a big radiator, a fan and a pusher fan and it still gets up there.
