Very clean single barrel Holley 2100 carburetor with new aluminum Ansen #338 three bolt to 4 bolt base adapter. I picked this up at the Pamona swap years ago for a '36 Plymouth with a 50's dodge inline 6 in it. I sold the car before ever mounting it. The Ansen has not been drilled yet in the 4 bolt area. The carb is very very clean and the butterfly and levers all move. Can separate for $75/carb and 25/adapter.
