Here is the 52mm F&B two-barrel throttle body bolted up to the same M1 intake manifold. The F&B is a 1,050mm unit with 52x55mm oval-shaped barrels, and flows 50 more cfm. It is a two-barrel unit that uses all of the stock Dakota linkage and fittings, plus it is much easier to hook up and works great with the blower.
