Jeep 4.0 Camshaft Suggestions

[williambmac]

As others have suggested, you are barking up the wrong tree here. If you want a 4.0 with a choppy cam, you're going to need to build the motor and get it tuned. Slapping an off the shelf cam in it with factory compression and no tune will result in terrible driveability and almost certain check engine lights. Plus anything off the shelf with enough duration and overlap to sound mean will probably have too much lift for stock valve springs. Also, what year do you have? Newer style cams have a very limited aftermarket selection. You could convert to an older style cam, but that's just another thing. All of this for sound from an engine that won't perform as good as it sounds. That's ricer.

I suggest you take your time, build a [stroker] motor on a stand slowly over time spec'd out the way you want including cam. Then plan on having it tuned. It still won't sound like a v8 and that's fine, but know that going in to it. Some of the best sounding engines are I6's. I've owned and played with many. Nothing sounds like a v8 though.

My Jeep I6 based stroker with a healthy cam and just shy of 9.8:1 compression:

That does sound sweet.

Thanks guys. Wasn't fishing for compliments but it's appreciated. I just wanted to show how not v8 sounding it was. I still like it, but a Ford 302 it ain't. IMHO some of the better sounding I6s only sound "good" at idle because you know what they sound like/do at 8k rpm.

So I’m new on here and I have a TJ with a 4.0 in it that I’m replacing with another 4.0 I got for cheap that I’m looking to build before I swap it out, I wanna put a beefy cam in it so I’m looking for recommendations? Not tryna spend a lot just want a cam that sounds good (choppy) with a little added power and torque, more so looking for sound than power. Was wondering if anyone knows about the Comp Cams 232 Camshaft

Yeah it's a freaking awesome cam but go with the Comp Cam stage 2 if you're going to run stock heads you see the power difference top end power and you will see the gas efficiency to really good cam I put it in a motor that I had I got almost 500 MI per tank on my Jeep and that 15 to 18 gallon tank and top end power I was able to go up hills a lot a lot a lot better without shifting from filth to 4th the top end power was able to take the hill and 5th gear with not a problem just step on the gas a little bit more and it pulled you right up with no falling on face like it used to hope this helps you

And the 4.0 only has one head. And Comp doesn't do "stages" with their cams. And please oh please use a freaking period every once in a while.

Everyone knows its his throttlebody spacer and cold air intake that added 75hp!

Skyline which cam did you use?

I have a comp 231 ground with more lsa. Wish I'd gone with a 235

I'll have to look up the specs. It's basically the largest cam Comp offers off the shelf but nitrided IIRC.
