Carb looks much better with the correct needle and seat and primary bowl. I sold my 4557 months ago for money to continue the restoration the JL8. It was dated wrong for my car anyway. I would like to get a more correct looking Holley 780 for my L78 and don't want to waste money on the 3310 since it's been messed with already. If I find a decent carb, I will be sending it your war Eric. Can't wait to hear how well this Nova runs with the rebuilt carb!
