Well I ran into a problem with the 1406. That would be the air cleaner. The old after market deep base unit off of the holley doesn't fit. The Edelbrock is about another inch wider. I can't add a spacer because it is almost into the hood now. I think I need another air cleaner base. It needs to be a deep base and also wide so it can miss the auto choke and accelerator linkage. Any ideas???
