I had a massive hole in my transmission tunnel for years when I first bought my 40. I was shocked when I finally patched it up how much more quiet the truck was.
Now, I said “more quiet” which is not to be confused with “quiet.” My 350 has a 17” rigid, clutchless fan. When I start approaching 3000rpm around 60-65mph - it sounds like the engine is going to throw a rod. You have to yell to have a conversation in the cab.
