go back to the original Quadrajet, a great carb and you get the best of both worlds, economy and performance. If you want to upgrade the intake system, Edelbrock makes one called the performer rpm that is supposed to be a little better than the stock one. Some people put an aftermarket electronically triggered distributor or points replacement kit for longevity, but it doesn't do much in the performance field over stock. There a many choices for headers out there, hooker, headmen, are two that come to mind immediately. like I mentioned in your other thread, simply rebuilding the 350 to stock specs will bring it back to peak condition but there are also many camshaft upgrades that will perk the engine up nicely. Since you have a machinist you trust you should probably go with his recommendations.
