I am rebuilding my stock 318 2-bbl and not too sure on what performance parts will work. More specifically what camshaft I can install to give it better performance without going to a 4-bbl carb. My van is just going to be a traveling van to take on road trips and maybe some camping trips, so I am wanting something that will perform at highway speeds and on hills. Have any suggestions on a rebuild? Something you would do if it were your engine? Any tips, tricks, or suggestions are appreciated. I have tossed around the idea of going to a 4-bbl carb, so that's not completely out. Just want to save as much money as possible since my budget is really tight.
