I have tried several combinations of carb/ manifold setups on 235s. My favorite from a drivability and plain cool looks is the offy 2 carb setup using 2 progressive Carter/Weber 2 barrel carbs. This is a very nice setup for trucks with only mild modifications to the fender brace rod. The setup comes with electric auto chokes. Set this up with an HEI distributor and you will think you got yourself a late model fuel injection engine. Just turn the key, hit the starter and she starts instantly, no hesitations and great fuel economy.
Got my setup from Langdon's Stovebolt, he is good to deal with.
