This is impossible to find. An original factory assembly line 1967 Corvette Holley Tri-Carb Choke Cam in green as original installed by Holley. I have had this for 35 years. I used it only for Judging my various 1967 Corvettes then immediately removed it. This is the Holy Grail of Carb Parts. It’s crisp, clean and works perfect to properly mange the worm up cycle of Corvettes with Tri-Carb option. Put this on your car for NCRS or Bloomington Judging and watch the reaction. I’m no longer active in the hobby and starting to sell my valuable parts.
