I have a 1978 350 engine with stock shortblock to which I have added Vortec heads a Edelbrock performer Manifold and Cam kit. The thing is the manifold is a spread bore. I was going to buy an Edelbrock performer series Q-jet but they do not make them anymore. I want and electtic choke so I guess the Holley 4175 quadrajet replacement is the logical choice. The only thing is I never liked the Holley mostly because of a bad experiance with one. I was wondering if anyone had any other ideas. I do not want to run an adapter plate and I know there are summit rebuilt quadrajets but I am not comfortable with them just looking for options here. Any ideas.
