So i thought i read somewhere that the cams from a jeep cherokee V6 fits my truck, also a V6 and a 99', but is slightly more aggresive. I would like a little more power without raping my gas mileage. I know i know its been posted before but the exaust and K&N helped my mielage a little (like 1-2 MPG, ill take it) so its time to go down .

So is it true and what kind of difference would they make?? Im also open to suggestions for other cam options, just heard this and it seemed like a good idea.

Also heard that putting the intake manifold from the V8 (dont remember what size)with a spacer, also increases power. Is this true??

Thanks

 

Jeep Cherokee's used the old 2.8L v6 sourced from GM for a while and they were known for blowing up. The later 6-cylinder Cherokees are a 4.0L inline 6, and that cam won't work for your 3.9L v6. The v8 intake manifolds won't work at all because there are 2 more intake runners that wouldn't line up with anything, not to mention the dimensions period. There are parts to be found for the 3.9L though.

 

Cool thanks for the info. Any liinks, and what size cam would be good for me (dont know what stock is)?

Thanks
