Cams in a stock 4.0?
Well i have my stock 4.0 out of my 96 all torn apart. I want to add some more power and I always had a craving for that cammed sound. What are my options as far as cams go. I want it to sound cammed. And for anyone who says "your gonna have vacuum issues" i already have a vacuum pump runing everything non evap.

A performance cam, by itself, will do very little.
If you are just after the sound, get an exterior speaker and a recording.

Exhaust and intake work. The new cam will try to move more air, and if it can't, you've negated your gains.

do you only want a bigger cam for the sound? what is your plan for engine management? I'm sure if you google some generic form of "jeep 4.0 camshafts" you'll find a lot of them.
do you know what the numbers on a cam card mean? overlap? what having a high lift/low duration combo does and vice versa? you ever measured for pushrod length? set hydraulic lifter preload? degreed a camshaft? shimmed valvesprings to proper distance from coil bind?
there's more to a cam swap than putting a different camshaft in the block. I see it as nothing but a problem creator on most engines. the attention to install and negative effects are not worth the return.
