Just picked up a Galaxie 2V 390 out of a 67 car. I want it to be a performer not a economy cruiser. What are the differences between a standard 390 and a 390 2V? Are there a few simple change overs like higher compression pistons, a four barrel intake, carb and cam? Or are they completely different all together? Im new to the forum and new with working with the FE engines.
