I'm still trying to piece this readiator mystery together, so I've been scouring the gallery pages to see original setups and found this picture of Jon Miller's engine compartment.
http://www.stovebolt.com/gallery/images/miller_jon_1950d.jpgThe radiator flange is in the middle of the radiator. As I mentioned before mine is offset by at least and inch. Which means someone in the past changed that. That makes more sense because the cross braces have been cut out of the radiator support. He must have done that when he installed the 235 with a long shaft water pump. Now everything is new on the engine including a short shaft water pump. So I should have plenty of room for the radiator. But I don't. Hmph. I guess I'll bedoing some more head-scratching this weekend while looking in the engine bay.
