" 69 " - 440 what cam?
It won't take much for that 440 to feel powerful in an A-body. I would go with a Performer RPM, Holley 750 with vacuum secondaries, and for the cam, I would call Hughes Engines. The intake is pretty standard, but as far as the carb and cam go, you could get 50 different answers from 50 different people. That's why I say call Hughes and have them recommend a cam. Also, I'm not sure on hood clearance issues with the Performer RPM, if there are any in an A-body?
