I scoured the internet to find an answer to the SAME question, and I found several farm sites where grain haulers and farmers all had a consensus, the tried and true 1406 Edelbrock. I found a 1906 locally, the AVS2 updated model, for the same price as the old model. It's the readily available carb on most auto parts store shelves and they're dead simple to adjust. The electric choke works flawlessly and it holds it's tune perfectly. I cannot say enough good things about the positive gains I saw going from the same Holley garbage governed carb you have to the Edelbrock. You will want a 1/2" phenolic or composite wood spacer between the carb and the intake to help kill heat issues. The one (and only in my opinion) downfall to the Edelbrock is that the float bowls will boil dry easily it seems, and today's ethanol gas boils faster so you want it as cool as possible.
