Not much info from that link. It's a .270 lift and a stock cam is .265. That cam will give an itty bit more performance in a slightly higher RPM range. Definitely not worth the $200. Look on ebay and similar sites for cams and call your local dealerships to see what's available.
Are you looking for more power in the lower RPMs when off-road or higher RPMs while on the road?

Here's some more info you should read.

Hello there. I have the same engine in my 93 YJ. There isent much you can do to get more power. Your best bet is gearing or engine swap, but neither is cheap. I run 5.38 rearing in my 4 banger YJ. best thing i ever did.

Greencar-
I know there is a 2.5L camshaft on eBay right now. Here it is: camshaft . Also, if you use a camshaft with more than .450" lift, you will definitely need new valve springs. You do not want to experience valve float at higher RPM's, and that would definitely happen with a cam of .523" lift and stock valve springs.

Oops. I must have been dead assed tired when I posted that cause I don't even remember posting it.
My Mopar cam has .440" lift and made a significant difference in low RPM torque. I believe .440 is as far as you can go before having to install different springs.

What drawbacks would/does that .440 cam have at higher rpm? Been looking for a low rpm torque cam (RV cam?) like that myself and I don't mind if it compromises hp above 3000 rpm, but don't want it to mess with hp below that with too short an overlap duration. What do you find with rpm at 3000 or so?
