Summer is car show season in Michigan. So, after checking out the Orphan Car Show last weekend, this past weekend we went up to the little town of Davisburg to hang out at Billetproof. Basically, it's the most badass Hot Rod show there is. No six-figure trailer queens here. This is a show where surface rust is loved more than chrome, and flat primer as much as metal-flake candy coat. But what do you really come to a Hot Rod show for? That's right, you come for big, beautiful motors. Check out the gallery below for our favorite mechanical details from the show.
