Running a 19 inch clutch fan with stock shroud on my 69. Had to switch to the longer water pump which put the fan a half an inch further into the shroud. It's now rubbing a spot about a half an inch by eight inches on the bottom of the shroud. Would it be better to cut that much out of the shroud or go with a inch shorter fan? Don't want to lose any cooling. Did they use a different shroud at the factory when they switched to the longer pump? All comments appreciated.
You can get a different clutch fan that is about 1/2 shorter which should pull the fan back out. I can post a link that shows the part numbers and lengths of the clutch fan shaft if you want, I just have to find it. Measure the lenght of the shaft on your clutch fan and we can see if you can go that route.
