If I had to buy a new carb, I'd be looking at a Edelbrock AVS 2 or a Street Demon, TQ knock off. I never liked Holleys on the street. Did a search on that Holley, list number and nothing came up.
1406 eddy has been my go-to for 20 years. But I have had good luck with the Holley 1850 also. But you can dial the eddy in if you spend the time and has always seemed more reliable for me.
