My two cents worth:

I would not consider cutting the body until I had done all of the other cooling improvements noted in previous posts and articles. I also have a 302 that does not like traffic but cutting this brace is not anywhere on my to do list. Ain’t gonna happen, not now-not ever.

Also, I disagree that these motors like higher temps. Mine is happiest at about 170. I have lived with three Tigers and five motors and none of them were happier at higher temps.
