My 109 stage 1 has a Discovery 3.9 in it with an Edelbrock manifold and 4 barrel carb. I was recently told that switching from the original cam to one designed for carburated engines will make it run smoother. Not being an expert on cams myself I was wondering if anyone could shed some light on this. I'll be pulling my intake manifold and heads to replace gaskets soon so I was wondering if a cam swap will help also. Thanks
