I believe the Crossfire fuel injection can be converted into a carburetor. However I dont know where to find this sort of conversion kit, or how much it may cost. I would like for my 84' vette to have a carb because I plan on adding some performance parts. I think if I can get it to a normal chevy 350, I can treat it as a muscle car without the restrictions of fuel injection. Speaking of which, any suggestions on where to start for basic performance. It already has flowmasters. I would like to start with the basic engine components, headers, then maybe even a supercharger. Thanks for the suggestions.
