Dual Plane vs Single Plane injection
I have been looking at various kits to convert my 351 to fuel injection. I have an edelbrock preformer rpm air gap intake and was looking to use it in the build. I have heard that a dual plane intake dosnt work well with fuel injection and a single plane is a better choice. Any truth to this? if so how does it affect tuneability?

I was thinking about building a port injection style FI ( injector in the intake runner...? ) with my edelbrock preformer rpm air gap manifold. I have been looking at using a 4 barrel throttlebody and mass air flow censor like the system from mass flow.

I don't think there would be any real disadvantage to using the intake you have now, relative to how the engine was performing before. The main reason why most MPFI systems use single plenum manifolds is because they don't need the crutch effect of the dual plenum to keep velocity up and keep the fuel in suspension. But, obviously, the manifold you have performed well for you, and it'll flow just as much air with EFI as it did with a carb, so it should be satisfactory, I would think.
