I have a pair of factory Holley 600 DP blower carbs and fuel lines for them. They were on my car for 2 years until this past summer when I replaced them with EFI. They work fine. Also to go with them is the dual fuel line setup for side mounted carbs. Price $500 plus the ride. I will ship them in the boxes my EFI came in. Carbs are located in Saint John, New Brunswick Canada. PM me with any questions.
