APD tends to push Max Speed carbs that are way too large for the engine application. I borrowed a early Max Speed 1050 a few years ago and had great success with it on a 582 engine . When I had them build me one they sent one that was much larger in CFM ,the consistency was not there and it had to be run at a much higher cruise RPM.
I now use a Stinnett baseplate stop from Number 1 Stop and a ATM carb built for my combination. Deadly consistent and absolutely the best fuel curve I've ever seen while on the stop. ATM also makes an excellent baseplate stop.
