I have a 49 Ford 2dr sedan with a good running stock flathead v8. Its only performance modification is a set of headers and dual exhausts running through a pair of glasspacks. I'm looking a tweaking it a bit but don't want to trash driveability. I am definitely going to convert it to twelve volt with and alternator and also change it to and electronic ignition. Beyond that I'm considering aftermarket performance heads from one of the manufacturers and either an intake manifold change with a pair of dueces or a small four barrel. From what I've been reading the latter carb and manifold change is a bit easier and more reliable than the dual carb arrangement. As far as heads are concerned I don't want to up compression much above 8.0 to 1. I would like to stay with the stock cam too if possible in this scenario. Will they adequately handle the extra fuel with the stock cam or do I need to go to 3/4 race grind?
