Engine Good cams for the 258

[grimmjeeper]

Now that I'm getting my CJ on the road, I'm finding more issues.

I have intermittent valvetrain noise in my AMC 258 i6 / 4.2l that sounds like a partially collapsed lifter. So my plan is to just nip it in the bud with a camshaft swap, whether I do a full rebuild or not.

I'm looking at the Comp Cams Xtreme 4x4 206/214 cam. It has 206/214 duration with 0.462 Edition /0.485 lift and a 111° LSA. Stated RPM range is 800-5,000

My intent is to have a good idle and mid range torque. I don't need top end as this is a driver and weekend wheeler.

Anyone have experience with this cam? Any good alternatives?

I went with a new stock cam and lifters.
Intake/Exhaust Duration of 270°/270°, a duration of 197° at 0.050 lift, a valve lift of 0.397 inches, and a Lobe Separation Angle (LSA) of 112°.

I used a CC cam. Only one they had for that engine, w/EFI. I like it. I did have a collapsed lifter earlier last year. Got it back working again.
