I used a Holley 350cfm two barrel. I like the Holley because it is easy to tune. I put a air/fuel meter on it and have adjusted jets and power valves to maximize gas mileage and still retain good acceleration.
As far as the Pulse Air system....mine was already removed when I got it. All I have at this point is one vacuum line going to the distributor for vacuum advance and one going to the brake booster.
