I have a Buick Regal T-3 turbo on my 1953 Chevy with a 261 ci. Just got it running good a few weeks ago. The carb. I have on it is a Carter AFB 500 cfm. Did have to downsize the jets to lean it up a lot. Using an electric fuel pump and made up a fuel return system and have the regulator setting 5 pounds of pressure. The boost is set at 8 pounds. It's liking gas really well.
