Cruising with a factory performance intake manifold on your classic muscle, most likely means the not-so-performance stock carburetor is still there, robbing horsepower. So, what's keeping you from bolting on a modern performance carb? It's the strange bolt pattern on your intake manifold that the performance carb companies happened to steer away from. Finally, you have a way to swap leaky antiquity for a modern performance—Edelbrock Carburetor Adaptors.
All it takes to revitalize your ride is unbolting your factory carburetor, throwing the correct adaptor or plate on the manifold and bolting the new carb down.
