Ditto on cooling turbo'd 4020. They get hot. Some removed the air cleaner from in front of the radiator & mounted a remote cleaner elsewhere to allow for more air entry to the radiator.

We put the full M&W kit on a side console 4020 in 1974. Drove to Gibson City & picked up the kit at the parts counter at M&W factory. Our kit included the aluminum finned oil pan.

The oil pans are now bringing big money. I don't know of any for sale for a reasonable price.

I suspect the 4010T in the photo probably has been made 404 c.i. Most have by now.
