I've had it with this old original Holley. Have been trying to stop a fuel leak and stripped the rear fuel inlet fitting. I think I want to put this date coded carb in a box to stay with the car for the next owner, and buy a Holley Street Avenger to replace it.
Original carb is 780 cfm. Street Avengers come in 670 and 770 cfm. I'm thinking about going down to a 670 as I don't race this car and don't go above 5,000 rpm hardly ever. In fact more like 4,500.
Talked to a Holley tech guy and he agreed and said I'd probably get better gas mileage to boot (not that I care).
I would go to an electric choke and block off the exhaust crossover to remove the heat under the carb (I've already removed the butterfly from the heat riser.
What do you guys think?
