15-20 yrs ago I didn't have time to rebuild the Holley on my 351w so I went with the 1406 Edelbrock and a 1" adapter plate. I had great success with it. Holley's set more lengthwise on top the engine, where Edelbrock set more across the top, The 1" adapter plate gave me a higher clearance the carb needed to mate up with the trucks throttle control.
