Trucker you really know your stuff!! So the '36 may be a fair engine to mess with then as far as the evolution of stovebolt 6's goes. My brother is a 20 year veteran as a automotive machinist business owner and ownes 2 '36 coupes. He wants to dive into these 207's and see if he can massage and blueprint them. I own two '36 engines and a '35. I'd be interested in your spec sheets for sure. Was the 207ci ever called Blue Flame or was that in '53? Sorry to rob your post Rat Rod Girl but this info is awesome ......Rick
