I'm looking for idea's on the best way and parts to replace the lean burn ignition / intake and carb. I have a completely stock 400 ci motor and plan on keeping the lower end and heads stock. I was thinking about the distributor and orange box ignition conversion kit that JEG's sells, Edelbrock Performer Intake and either a Edelbrock 600 or 750 square bore carb with an electric choke and the manifold/carb adapter plate.
