Nice looking engine, I like the green. I will say this...I didn't think that setup would physically fit into the engine compartment without hammering a cavity into the firewall for the back carburetor. Have you confirmed it will fit or have you anticipated massaging the sheetmetal.

I had this same setup on a 235 in a car (it fits in a car). I didn't use the Rochesters. I used three matched Strombergs that are quite a bit smaller (venturi) than the Rochesters. I can't imagine how progressive linkage would work on this setup...mine were all tied together and worked beautifully. Keep us posted on your progress.
