RARE! 1 of 11 made (from the research I have done) after calling the new CB performance they did not believe me as to what I had until I sent them pictures. Sbc Chevy intake made by CB performance in the late 60s early 70s with 2 weber idf40 carbs with 4 air horns. This was unused and untouched NOS up until this spring. Have over $100 worth of jets that are included. Menasha WI 920 850-5262
