Howdy Eric n friends of the forum!
For anyone with knowledge and experience with the 2002 Dodge Ram 1500 with a 4.7L, I’m having trouble finding some cams for this little torque monster. I’ve already contacted Airram, and emailed Comp Cams, nothing for the 4.7. I guess a few years back there was a little resistance movement with the whole aftermarket cam thing with the 4.7. Well, it seems like that time has died n there are no more cams to be found, at least through Airram.com or Comp Cams. Does anyone happen to know where I could turn to next, in the hope of finding some cams for this engine? I see people getting cams for their 4.7 all the time, n I want some too, it ain’t fair! LOL! Any input would be appreciated!
Thanks guys,
-Steve

tried looking for cams for this engine bud, and i am not having too much luck either, do they have ratio rockers? and if you put a cam in it make sure your valve springs and pushrods can take the hotter cam or more aggressive rockers.
In my opinion the 4.7 has enough problem with keeping the rocker arms where they belong without increasing the lift and duration. There isn’t enough demand for Cam companies to research and repair the poor engineering that Mercedes put into it.
I do understand what you mean about the factory rockers. However there is one thing you must remember, the entire valve train is hydraulically driven (which thus could be the Mercedes engineering that you speak of), such as lifters, chain tension, etc. I’ve found solid lash adjusting lifters, and stronger springs for this engine, in which when installed them rockers are going NOWHERE! And also this engine is overhead cam, so no push rods to worry about. I do believe the factory rockers are ratio, but don’t know the specs. I do believe also they’re rolling as well, haven’t looked into it much yet. But still you gatta have faith in this little torque monster! Take care of it, n it will take care of you! I have over 103k on my ’02 (which isn’t bad I guess). Mother bought it brand new back in ’02 and I received it at around 65k, and let me tell you I’ve driven the living hell out of this truck. Plenty of jack rabbits and redlining (wait…what redline? ;D), and very few repairs, in fact only two since I’ve had the truck. They both had to do with the cooling system. That’s it though, never any problems or failures with this engine, and certainly never had a rocker fall off on me haha! Factory head gaskets are still strong as the day my mom bought the thing (and she has a heavier foot than I do!). Idk, it’s been a VERY good truck to all of us, despite how we drive the thing. The only thing is I could use a little more power than 235hp lol!
Getting back on point, the cam makers told me they would need the cores of those cams in order to do anything with them, that’s the sucky part. The thing is, I know Comp has made cams for the 4.7 before because I mean, just go on youtube! I just hope I’m not too late in the game as far as finding someone who can still make them, cause I ain’t switching to a hemi anytime soon, don’t aim to either.
Dodge had the HO version of the 4.7 used in several vehicles. I have an 05 Dakota and an option is the HO motor, which has cams with a steeper grind. Not exactly like a .280/.480 cam, so you’re not gonna get that nasty old school lopey idle, but it’ll add a few ponies. And those sticks are still available. I wanna say that either Lunati or Crane are willing to make a custom grind, but I’m guessing they’d need the originals for a point of reference on how to grind them.
I had a 2002 Ram 1500 4.7L and ended up selling it and getting a 2005 Ram 3500 Cummins.
There is not much out there for the 4.7L. The Hemi and Cummins have tons of parts for them.
