Jeep Strokers

Could someone explain to me what are the benefits of using a performance cam as opposed to my stock cam ('93) on my stroker build?

Stock cam has duration of 270/270, and gives me a better DCR than let's say Comp 232-4 (250/256). So why should I buy a new cam and stiffer springs? Is valve lift the key here?

there are tons more factors involved in a camshaft then JUST duration. Lift, Duration, Lobe seperation, Ramp speed, Centerline angles.... These are all characteristics that "define" what the cam should be expected to do. If you are interested in getting more low end torque, or higher end horsepower, I'd suggest a little googling on the characteristics in a camshaft, and what each aspect effects. I think the cam, and its effects, are the trickiest part to learning of how any engine produces power. If you can get a decent understanding on that, and can even just narrow down your cam selection, then you should pat yourself on the back and have a beer

While the stock '87-'95 cam does have an advertised duration of 270 degrees, the 0.050" lift duration is only 197 degrees so that indicates that the cam has a slow opening ramp rate. Valve lift is 0.424".
Given all the reliability problems associated with flat tappet cams these days, I suggest you keep the stock cam/valve springs/retainers and just replace the lifters.

I agree staying with the stock cam...........................But if you want more then the stock cam, you should read up in the FAQ Section on cam FAQ's..........heres the link to help you out

Before you use your old cam, I would check all the lobes to make sure they aren't worn too bad.

I found this while searching : http://www.amotion.com/tech/camselect.html

...might be of interest.

Ok... after reading all evening about camshafts, lobe separation, duration, lift, etc.... I'm more confused than ever!!! I'll sleep on it, althought I'm leaning towards the Comp 232-4, still.

What ever you decide I don't think you can go wrong with the comp cam 68-231-4 or the 232-4.... why are you leaning toward the 232-4 over the 231-4? I have compared as many cams as I can on a desktop dyno and while it doesn't give real world numbers it is still represents comparable numbers and I haven't found a cam that does as well on a stroker that the comp cam.

Leaning towards the 232 because they say it's fuel-injected compatible, and it's probly less prone to ORBII fault codes in my opinion.

But I'm still wondering if I should keep my stock '93 cam after all... Now it's really time that I go sleep on it...

The Jeep PCM will have no problem with the 231
