Hi, I have a 28 Ford Model a 5 window with an early production 327. When I bought the car it had a Carter 625 CFM carb. When I would stomp on the accelerator it had a major bog at the bottom and less than stellar performance. My brother has lent me a 650 CFM Holley double pumper to try. It has a new rebuild kit in it. The car also has a mild cam in it but not sure exactly which one. It has an Edelbrock intake manifold. It also has corvette ramshorn OEM headers. My question is what bolt on mods can I do to maximize the potential of this engine without decreasing reliability? Does anyone make a set of aftermarket headers that will bolt on the the exsisting exhaust system without having to cut and weld the exhaust collectors? I'm not wild about the look of the rams horn headers, I'd like to go for some chrome aftermarket headers being its an open hood car. I bought some chrome edelbrock signature series valve covers and air cleaner so I am going to install a pcv system and plug the old road draft outlet. Here's a pic of the way it sits now.
