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!

Here's a couple of links for reading:

Performance Camshafts, Lifter Kits and Matching Valvetrain for Small-Block Ford - Edelbrock.com

That should help in your selection...Good Luck

Given the criticality of the component- IMHO, to the engines performance and life, to me it makes sense to use a cam grinder who will talk with you directly- even modify the cam grind to fit your needs even better and to address the possibility of cam lobe failure with the new oils. I don't like speaking to a catalog parts sale person- they really don't know any more about the cam than what they are reading- companies like Summit, while their bulk purchase agreements are great for price, when it comes to making an engine breathe, there are so many variable including elevation, humidity, fuel blends/available octane, most cam mfgs will vary a "core grind pattern" to match the external impactors in addition to the internal impactors- which today IMHO makes the different between and engine that runs well, to one that just seems to run a little bit better, smoother and gets better mileage than expected. And remember, advertized lift/duration/lobe separation is just that- advertized and not the specific grind including ramp profile that is used on the cam

whatever cam you choose make sure you get new lifters to go with it, so they can break in together.
