Hi all, I just joined and have a 47 Plymouth Special Deluxe Club Coupe. It runs and drives great. It has the original flat 6 motor and trans. 3 on the tree, 6 volt, updated interior and updated wheels. It has new paint and floor pans replaced. My question is what mods can be made to this motor to improve it? Are there any drop in modifications, brakes, motor/trans options I may want to consider? Thanks for you input.
