Manifold was bought for use on a 1968 Mustang A-sedan road race car that I vintage raced.  Rules changed making open plenum manifolds illegal, and I never used the manifold on the car.  Manifold was installed on the engine one time at Keith Craft's shop in Arkansas and has dyno time only - looks brand new.  Runners have been only lightly "cleaned up" and professionally port matched by the late Raymond Grice in Durant OK.  With this manifold on race gas only, the 303 CI engine made 547 hp and just shy of 400 lb-ft of torque on the dyno with a 750 Holley HP carb. Have six new sets of TFS intake gaskets that go with the deal.   In the original box...a deal at $275 since new 2921's now cost over $300 at Summit with no port work, and the gasket sets alone are worth $120.
