Here's a couple of links for reading:Hey guys, I have yet to understand different kinds of cams. After I get my new headers and exhaust, I'm going to get a new cam shaft. I was wondering if any of you could gear me in the right direction, or even recommend a specific one. I have a 1969 coupe with a rebuilt 302 with an edelbrock performance 289 intake and an edelbrock 4 barrel carb. It's my daily driver but my idea is to increase performance a good amount and make it faster. That being said I want a cam shaft that will definitely pack some power but not over do it. I thank anyone willing to put in their thoughts or suggestions!
