Hi Ralphie,
This is a little off the subject. I have a 302 GMC in a 40 Chevy and have run three 32/36 Weber down draft carbs on it for about 20 years. It runs well and has built in progressive barrels running on the smaller 32mm most of the time. My best milage was almost 18 mpg in 5th gear mostly and keeping it under 2500 rpm. I made the manifold but you could modify an old GMC manifold to accept these carbs. They were on many small imports and I see them on Ebay. Radar
There are pictures of my set up at
