My brother is building a tri-power for a 283 and has decided to cheap out on his approach. He has one usable carb and he is mounting it in the middle and just putting dummy linkage to the other carbs.
Somehow I think this one is more about the look than the performance....
As he finds more good carbs he may improve it, but today the motor isn't even in the truck ('36 Dodge) so its not critical.
