Mopar Performance has a roller rocker for the 4.0 (probably a Moroso or ?)........has anyone done it ..or know anyone who has? .....or am I going to be trailblazing here? The installation requires a spacer for the valve cover so it apparently adds some height under the hood.

Re: 4.0 roller rockers ......anyone? thanks!

I tried to post a couple of times to no avial.....I hope this one makes it.
Thanks...for the effort! Ya....they appear to be expensive...dorfs found a price of $68.xx somewhere. I'd like to find out who actually manufactures them.....I doubt that Chrysler actually tools the stuff....probably a relabel job. I'll check into the 304 rollers......sounds like it might be a whole bunch cheaper.
Yes, this is a poor "bang for the buck" installation......a cat-back and/or chip mod might yield more for less. I hope to relieve internal friction and maybe pick up a few ponies along the way. Longevity is my goal. I also want totally reversable bolt on installations (mainly if I ever need to use the warranty).

Re: 4.0 roller rockers ......anyone? update

Cifford Performance has them.......seems that they want around $425 for the set... straight bolt on -no machining of the head as with some others (drilling and tapping the stud mounts).....the valve cover spacer is $135.......$560......still salty.........I still haven't gotten to the 304 rollers.......
