So I got a 96 motor getting new seals and junk to bolt to a 4x4 ax15 for the 4x4 swap in the mj. I'm thinking about getting an aftermarket cam since I've heard the stock one is overlapped for the non egr system. Also the 91 HO in the mj blows on the low end. Then I have a renix xj that rocks even though it runs like a tractor.
After looking at this chart http://www.angelfire.com/my/fan/Jeep4.0Camshafts.htm
The stock cam profiles aren't whats expected. 91-95 don't make peak torque till 4k but still have the renix cam that made it at 2.5k in those motors. The renix has an egr system so shouldn't the 91-95s have something different for emmisions? Also the renix cam is all around bigger but does not rev as well as the HOs, even the ones with the same cam. So whats the deal?
Also if anyone cares I'm looking for this motor to make good torque and be efficient as possible. I wouldn't mind if it ran more like a tractor but this jeep might be getting 4.10 axles with the 5 speed and stock tires. The renix cries at 2500 on the highway but that might just be my case.
And last I'm worried buying an aftermarket cam from all the failures I hear with multiple brands. Many of them are even a far narrower lobe measurement from the stockers, shown in this thread.
