cam shaft

I have a AMC 258 i6 / 4.2l , headers, dui dizzy, and stock carb. I'm looking for a cam to give me just a little bit more performance.

I used the Comp cam 68-201-4. Not a radical cam but gives it a little more power.

That is a good gas mileage cam. I'm running the x-treme 4x4, part number 68-239-4. Good all around cam, nothing radical at all. Makes the 600 CFM Holley go woot woot LOL.

I'm also running a COMP x-treme 4x4 cam, from everything I have read COMP is the way go, the other couple of folks I have spoken to that went with a Crane and they had tons of issues and ended up swapping to a COMP.

Do your homework, some of these require increased compression, most of them require you to use the double spring valve springs, heavy lifters, and if you get the head decked you're going to have to use a not stock size pushrod. I know all of this from my experience rebuilding the top end of my AMC 258 i6 / 4.2l .
