Re: Simple Cam Question

I am sure it would be comparable to the 5.7 cam setup I'll be doing in the next couple weeks. Timing gear set ~$175, cam ~$450-500, kit (springs, pushrods, etc.) ~$110. Then there's oil/filter (mine due a change anyway), misc. gaskets, hardware, and any other parts you may want to replace (serpentine belt, water pump, etc.) while everything is apart. I am figuring I'll be into it ~$1000 total in "stuff". I am also going to try the swap without removing the heads, which eliminates some labor time and parts expense on the Hemi. Don't know if you would have to remove the heads on the 4.7 or not. If you're not going to do the install yourself (I am) you can figure (I am guessing) ~$600-1200 in labor, depending on the complexity and time required for your 4.7 engine. If you have to remove the heads for any reason I'd recommend a slight (Hemi guys do .030") milling to slightly increase compression, and maybe even computer numerically controlled (CNC) porting. Porting will set you back in the neighborhood of $2000. For me the gain is not worth the $$$ though.....~25-35 hp.

The cam I am going to use in my Hemi has been around for about 5 years and is well proven in 5.7 LX vehicles to deliver ~50 hp, ~35 ft. lbs. of torque, more MDS "on" time and a little better fuel economy. That, of course, is if you can keep your foot out of it......which I know I can't. I am sure there are numerous similar cams available for the 4.7. Check out some of the major cam manufacurer's web sites.

I would caution anyone that is planning this mod. on any engine to NOT "over cam" your ride, unless you have the other normal performance mods., including a complete high flow intake and exhaust, including headers, and the appropriate aftermarket tuner. A specialized tune may be required for some cams, adding more to the overall cost. Good luck on your search and let's hear what you come up with after more research.

Re: Simple Cam Question

its about 1/10th the job of the 5.7.....the 4.7 has 2(TWO) cams under each valve cover. Its about an hour job for an experienced Jeep mechanic on each cam. Some remove the intake manifold and some just remove the valve covers. Most just do the HO cams for about $300(new...less used)...or you can send the ho cams for a custom grind. You'll alos need the beehive springs($30 if I remmeber correctly)You'll need a tuner as well. BEST mod for the 4.7 Jeep IMHO!

Re: Simple Cam Question

sorry...they should be on here somewhere...

if not...there is only one HO cams from Jeeps....2002 grand cherokee ho's. Last I heard they are hard to find. there was a dealer in Texas selling them for like $200. But justforjeeps may be your best bet to help you find them.

$30 for the beehive springs? I could have sworn I saw them for much more which is what kept me from buying them.

Re: Simple Cam Question

30ea?

yep, the hemi and the 4.0l (cam in block) engines you have to pull they cylinder heads to remove the lifters. Theoreticaly if you had 16 pen magnets you may be able to grab the lifter and pull it up enough to slide the cam out the front of the block without removing the heads... That said I have not tried and have no idea off the top of my head how realistic this would be, reguardless you still have to clear out everything in the front of the vehicle to make room for the cam coming out unlike the cam in head 4.7 that will lift off the cylinder head.

Your biggest issue is the special wedge tool used to keep the tensioner from expanding... IF the tensioner expands (to the next step in the ratchet mechanism) the ONLY way to reset the tensioner is to remove the front cover and pull the tensioner out and use a vice to reset the tensioner.

Re: Simple Cam Question

Real soon I'll let you know how/if the magnet trick works on the Hemi. Got my magnets, most all of the parts/tools I need, and cleaned up the garage in preparation to start working on the swap within the next few days. I don't have the time to do it all at once, so I'll be taking my time and doing a little as time permits. I was looking at everything in the engine compartment a little tonight, and there's a lot of stuff that has to be moved, removed, or tied up out of the way.....and that's before getting started with the meat and potatoes of the job. Gotta be careful with the cheap looking plastic wire loom retainers that slip over the valve cover studs.
