Originally it was called the Maximum Performance Carburetor and the prototype used mini velocity stacks. This was changed when they went to production, Even then, the initial carbs were different from what the public received later on. For instance, the early race carbs had raised bosses on the top casting near the venturis. Production carbs do not. There are no ejector pin pads on top nor on the main side casting.The main well body have experimental part numbers and the raised boss inside the main casting between throttle bores is shaped differently as well. The actual production In-Line carbs have true idle circuitry as well. These early race carbs seem to have been produced between March and April 15th 1970

The pre-production RACE versions did NOT have idle circuits. The PRODUCTION versions did.
Shown above is a race version In-Line carb that was in possession by Kelly Coffield when he was doing work for a customer on it. Kelly notes the many little details that separated these early units from the later one which were actually sold over the counter
