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.

 

I have some supporting mods what all do i need?

 

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

 

I have a poeted head

 

drop a v8 in it, then you will have sounds

then you read more than I do...LOL

 

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.

 

Most people don't realize there is this much work involved at all. Just google how to degree a cam. Oh what fun that is!

 

I liked it better when it was poeted.

 

You can get that lumpy sound you want by just pulling a plug wire or two, free and easy to fix when you don't need it

 

 

Yeah well im already losing power so i dont need to loose more 😂, i thought 4.0s were supposed to be reliable

 

older vehicles are only as reliable as their maintenance.
