Hi Sean: Obviously something shifted. If you are sure all your motor mounts and tranny mounts are tightened and in place, is your radiator in properly? Check the shaft on the fan clutch for any play. If it wobbles that could be the problem. On my 300F and '61 Newport wagon with a 440 I have minimum clearance as it sounds like you do. I went looking for a fan clutch and they all had a shaft that was toooo long. What I needed was one no more than 3 inches front to back including fins. Finally at Napa we found one 2 15/16. It's application was for a Ford 460, which certainly would be enough for a 413 and 440. However the bolt pattern for a Ford fan is different than the Chrysler bolt pattern. Napa has an 18 inch fan blade that has 3 different bolt patterns, so I didn't have to go looking for a Ford fan. Napa's numbers are: fan clutch 273370, fan 209855. All of the listings I came across using the original part number led to a fan clutch with a longer shaft, which I couldn't use. I do feel that there is one out there somewhere. Hopefully somebody had better luck than I did. An option to buying the universal fan from NAPA would be to drill your original fan to match the Ford bolt pattern. I didn't want to do the drilling which might weaken the fan. I know I'll probably catch hell for what I have done, but I needed it just as summer was beginning, I did what I did and it works for me!!!! Good luck and Happy Holidays to all.
