How to choose a CAM?
Hey experts,

(Im no machanic but am learning quick)

I am swapping 304 in my 84 CJ soon and the motor has like 30k on it. I would really like to work on the motor too. I was thinking of upgrading the cam.
How do I figure out what Cam to get? What do I need to know about upgrading a cam? Any info would help.. Thanks.

(again, be gentle with me on the terms)

[img]/wwwthreads_images/icons/wink.gif[/img] JW, it usually depends on what the engine will be used for. Is it high RPM for sand dune work, or grinding up hill in rock at minimum RPM? Also, you need to contact American Performance in FLA about the upgrades on the engine. You could also use the distributor gear oiler enhancement as designed by Partsmike. I am working on a crankshaft oiler enhancement for our 304 as well, but I am not ready to go public till I get it a little more refined, maybe this weekend I can do some more on it. If I can get it figured out and bulletproof, I will post it on the BBS. [img]/wwwthreads_images/icons/crazy.gif[/img]

Re: How to choose a CAM?
I'm also looking for a cam, probably some sort of RV cam since you shouldn't rev your 304 up past 5000, any one have good experinces with any brand? I'm going to be putting in a new edelbrock manifold, carb and headers in the next few months (starting to horde the parts)
hey smiley man is this the right american performance? when I searched for it I came up with 2 in flordia

Re: How to choose a CAM?
Here in Jersey there is a lot of Mud, more Mud, and some more mud. I guess I would need some high rpms to keep the tires turning.... SO how do I figure out what cam? Or is that something you can answer? ;)

[img]/wwwthreads_images/icons/smile.gif[/img][img]/wwwthreads_images/icons/wink.gif[/img] None of the little moonguys around here are actually mud experienced other than running army 6X6's up to the eyeballs in mud feeding cows. I think dune running and real muddin' is different than that. There are some Full-Size Jeep and some truck guys that post here that can certainly answer that question for you.[img]/wwwthreads_images/icons/laugh.gif[/img]

Re: How to choose a CAM?
<font color=purple> Weellllllll, one thing to keep in mind is that too hot of a cam will require a different manifold, different carb, & headers. And are you going to spend all day "playing" in the mud or will you trailer it to competition events, run it for 15 seconds, & put it back on the trailer? For the former, a mild cam increase is tolerable. For the latter, you'll probably want to ditch the 304 altogether & get some more cubes under the hood. And even in competition, you need to be careful. Many "Street Stock" or similar classes have vacuum checks to make sure "pro built" racers aren't running against true daily drivers. For a mild increase in ooommmphf, I'd suggest the Edelbrock Performer cam & intake, along with a Performer 500 4-barrel carb. If Edelbrock no longer makes the AMC Performer cam, talk to their tech line to see what sort of specs would match up with that intake & get a cam from Comp Cams, Crane, or others.

This setup is just one of many & I'd highly recommend getting the cam specs & comparing them to similar profiles from other manufacturers. May want a little hotter, may want a little milder. But, this would be a pretty good place to start. </font color=purple>

Re: How to get the right help
[img]/wwwthreads_images/icons/laugh.gif[/img] I rest my case......this page does it again. How can you beat an answer like that one? [img]/wwwthreads_images/icons/smile.gif[/img] You have so much info now that you'll need the rest of the winter to decide.[img]/wwwthreads_images/icons/wink.gif[/img] Thanks, Tex!
