This is a popular cam swap for a true HP gain with 4.7 HO Cams. This will work on all 1999-2007 Chrysler 4.7L engines. Detail instructions on how to adjust solid lifters. The sold lifters are not required for the HO or the 08 and later camshafts but I would recommend them if you have the HO cams reground to correct rocker arm geometry. This would eliminate the need for shims under the lifters. I got the Solid Lifters (Lash Adjusters) from www.airram.com Also show to remove and replace valve cover gaskets.

Could you use the factory lifters with an HO cam? Would there be any problems with the valve train if you used factory lifters?
Love your videos. I really do love my 4.7HO… In my 04 overland… Plenty of power… And underrated it's a smooth engine… And I drove a hemi and honestly seat of pants feel goes to the H.O.
Hi Martin @martinbuilt , i´m doing this H.O. camshaft swap in my 06´ Grand Cherokee, also i´m installing the solid lifters and the Comp beehive valve springs that I bought from AIRRAM.COM. Your videos has been very helpful to my installation. I just wanted to ask you: what is the maximum and minimum gap that must have between the rocker arm and the lobes of the camshaft?; Another question I wanted to ask you is: do you needed to make a reflash to the PCM?, do you use any programmer or something like that to make the PCM work correctly with those modifications?
installed HO cams in my 2001 durango today and your video was very helpful! keep up the good work boss
Hey Martin,
Where can I find one of those timing wedges? Do you have one for sale?
Any ideas where to get high rise intake and better cams for a 3.7L?
Great video I learned a lot Big help thank's
Question for the master 🙂 are the 08 cams the same as the HO cams? Can I install the 08 cams on a regular non-HO 4.7? Just wondering because one came available at the pick a part
Anyone know what type of HP gains they're seeing from doing cams on a WJ?
I think the 4.7 is one of the most under appreciated engines on the planet. I've owned two of them (01 Dak/07 1500) and both were animals and served me well. my 07 1500 even towed better than my current 1500 Hemi. The bottom end torque they produce is outstanding.
Great video Martin, I run a 02 Dakota 4.7l that makes 586 rear wheel horsepower and I used these solid lifters and had some major issues. My question is how in the world can you use a solid lifter on a hydraulic cam?? The solid roller cams have a very different profile than the roller hydraulic cam. I'm running the 218/224 cams, granted they are regrinds. When and if your rockers come flying off at 6000rpm would you let me know please. Thank you
i have a 2000 WJ 4.0L inline 6. Could i do this modification or a similar modification?
Hey Martin, great videos. I found a set of 2002 H.O. cams and I also brought with me the air manifold. Is it better to use the 02 HO manifold or leave the one from my 07 Dakota? Will I need to use premium gas?
Thanks
Great video! What could be the possible causes of my 02 dodge 4.7 having light poping out exhaust after a ho cam install. It shows up most when I put on my cold air intake. It runs fine no lack of power but running lean up to 17 sometimes at idle. Air fuel all over the place. I have checked coils, plugs, fuel pressure, and changed o2 sensors. No check engine lights or vac leaks. Any suggestions thanks!
