In my efforts to fix the overheating problem on my '70 Mach 1 I'm replacing a 17" direct drive fan that's pretty beat up and chipped. I ordered an 18" fan and clutch thinking that the bit of extra fan size would help (and the sales person I spoke to said that was the correct factory size). Well, the fan fits inside my fan shroud (24" on a 351W) but there's only about 1/2" clearance all around. Is that enough space or will the fan wobble enough to clip the sides of the shroud?
I was thinking of putting it in and just seeing what happens. If I do it quickly then perhaps the shroud would just get a few scratches. But, if I bolt in the fan it's going to get pretty scratched up just from the bolts/washers so then I wouldn't be able to return it. So anyone have an 18" fan with the 24" shroud on a 351?
