 Subject: Unbeliveable price on 4.7 HO cams.
IP: Logged
Message:
I was at the parts desk to day and decided to ask how much the cams were for a 4.7 HO. I damn near fell over when I heard the price. $70.00 a peice. No that in no typo $70.00 a peice. That is in Cnd dollars as well. So I said to my partsman to comfirm this price and he did.
So I ordered 2 of them. Now I figure this is either a scew up in pricing or I will get some other part that I don't want. If I get the cams I will spec them out and see what the lift is on them and compare them to the stockers. I am all wound up now espessialy if I can get them for that price.

Right now I am hoping that they are cams that come and not some other part, seems way to cheap. I will defintely let everyone know what comes and I will give specs as well. I will should know Saturday that is when they should come in. I forget to mention that is my price $106 retail.
I haven't looked to see what it would take to remove the cams. I do know that you need special tools to keep the chain adjusters fome taking up the slack when you remove the sprockets. I am thinking 4 hour job for me the first time. Taking my time as well.

The cams are each driven by a separate chain, each of which are driven off an idler, in the approximate location of the ol'LA's cam sprocket. This idler sprocket, in turn, is driven from the crank in typical pushrod practice timing set fashion. The camshafts themselves are radical - although not in lift or duration. These are truck engines, after all: 0.443" lift on the intake, and 0.429" on the exhaust, duration is 244 degrees intake, 254 on the exhaust, partially compensating for the smallish exhaust valves. Overlap is only 18 degrees. This is an emissions, and torquer motor, remember.
What makes the cams radical isn't the timing, but the construction. They are hollow steel tubes with the individual lobes, of powdered metal, sinter-bonded in place. In fact, the cams, being hollow, are used to bring oil to the intake lobes, which have oiling holes. Cam (valve) covers are cast magnesium.

Just called the parts guy @ VanDyke dodge in MI. He said $199.00 for the left cam and $169.00 for the right cam. Roughly $328.35 and $278.85 Canadian. If you can get them for $70.00 and they are correct, you are getting a very good deal.

will the dealer install these new cams for me if I were to pick a set up? And if so, since it's an OE cam will this void my warranty?
I was one of the lucky ones to get the 7 yr 100,000 mile warranty, also for like $5 a month (that's what it works out to be) I went ahead and got the 5 yr 60,000 mile bumper - bumper warranty. So the last thing I want to do is void a warranty I'm paying for.

I asked about an M-1 intake w/ the dealer and asked if it voided the warranty...he said it voids the warranty on the engine but not for the whole truck. The way I see it is, the dealer looks for any small thing that you mod on the engine as an excuse to void it...best thing to do is not tell them and make sure you find someone that knows what their doing to install it to avoid problems.
Oh and the quotes Graphite stated sound like the typical quotes for cam prices...either the guy CW talked to didn't know what he was talking about or their having a discount. I called the dealer/parts desk about a high performance chip one time an I had to explain to him what that was...he thought it was the normal chip, sounded like he was really confused as to what I was really looking for. CW, hope you get the right part.

No I was right there when he looked it up. There could very well be a part numbering problem or something along that line. I asked today I will not see them until tuesday or wensday. I will keep everyone posted. I have to put these on a dial indicator and see if it has more lift. To see if it is worth while even doing the work. I may need springs as well. Like I said I will post the specs if I get cams and not some other part #.

Hope they are the right cams CW,I can find specs on the stock cam but none on the HO cam to compare.I take it that you are a mechanic by your post about checking the specs,like you know always check the specs because sometimes what you receive is not what you wanted,I dont know how many times I`ve got the wrong rings and pistons and cams, I do not trust the parts dummys as for tools the only special tool you should need is a timing chain wedge to keep the chain tensioner in place when you pull the sprocket off,I ordered a 01 manual for a dakota for our shop even tho we dont have dakotas in the fleet to service :) I willl take a look for you if you dont have access to a manual,let me know also there must be a cam position sensor that you remove before taking out the cam,I learned that the hard way once :) good luck man

I'm not sure that timing chain wedge will be absolutely necessary. Letting the tensioner take up the slack will actually help keep the chains from coming off the sprockets, just don't remove the sprockets from the chain. That will also make sure the chain doesn't fall inside and need fishing out. The cam position sensor is located on the underside of the sprocket, but go ahead and remove it anyway. A single bolt and you don't have to worry about it.
Piece of cake.

You`re wrong there Duner you always have to put tension on the adjuster with a wedge on any over head cam engine if you dont you will never get it back on with out pulling the chain cover off and pushing the tensioner back,trust me on this,all you need is a wedge made out of wood with a hole in it and run some mechanic wirwe thru the hole so you can pull it out and same thing with the sprocket just wire it together to the chain

Duner the only problem with not using the factory tool is that when this tentioner on the 4.7 takes up the slack in the chains it won't go back in without having to be removed from the engine. They only go out not in :(. they have kinda a cogged setup. This keeps the chains from rattling before the oil pressure comes up.
Have you done this before? If you have count your self very lucky. The tentioners on the cars only can be pushed back in with a vice.
Thanks for the offer Art I have the manual on my toolbox at work. I just keep forgeting to take it home to look at it. BTW I am a tech for DC.
Dr Q: I am staring to get some nasty wheel hop now. That is the only downside of what I have done so far. I thought that the Roadmaster would help but it really has done nothing as far as wheel hop. It is definitely makes it handle better and I am sure it will halp me haul my trailer. Living your dream hehe I am just single thats all. LOL.

Hey CW, now that you mention it - yes. I actually did it last weekend when I pulled the heads and ported them. ;>)
Since aluminum goes very fast - I spent about 16 hours on them. I didn't really do a full port job. I didn't alter the actual port dimensions for either the intake or exhaust. Most all of my work was in the bowls. The intakes were pretty good already. The exhausts were terrible! I now know why the 4.7 doesn't respond to intake/exhaust mods like other higher rpm engines I have dealt with in the past. The exhaust valve is relatively small, but the bowl under it is closed in by quite a bit right under the seats. It needed most of the work. I just opened up the exhaust bowls and smoothed both the intake and exhaust bowls under the valve seats. I also cleaned up any casting garbage and narrowed up the castings around the guides to give them a better chance of flowing. I'll let you guys know how big the difference was once I get it to the track. So far the "butt dyno" says there was quite an improvement!
I just may end up switching cams in the near future also.....

Well you are one up one me I haven't had a wrench on the 4.7 yet. I go off of the tech videos I watch. This summer I might have to try doing somthing like porting the heads. There is a pair in the cornner of the shop right now I will have to take a look at the exhaust ports and see what they look like. Determin if I can do anything with them myself. But after seeing the design of the tentioners I still think you are lucky. The tensioners run off of oil pressure there must not be a primary spring in the tentioner that is why there are the cogs to keep them from backing off when the engine is not running.
Duner I urge you to tell me what works as you do it on the 4.7. Need all the buddys I can get to help me work this motor over. I am hoping the exhaust duration and lift is higher on these new cams to help out as well.

I was prepared the the worst case scenario...... I had a timing cover gasket standing by in case I had to get into it that far. I was actually dieing to tear it all down just to check it out! After looking at it all, it seemed like a lot of work just to satisfy my curiosity. I would have if I couldn't have gotten the sprocket back onto the cam. Since I haven't really turned many wrenches since my racing days, I am amazed at how nicely they make gaskets now. This O-ring type stuff is great! hehehe I ended up returning about $250 worth of gaskets that I didn't have to use!
If you get a chance, pull one of those exhaust valves out of the head and look into the bowl. You'll be amazed and how much of a step there is where the machining process for the valve seats stops. All of the exiting exhaust gasses will have to make it past this step before it can actually leave the cylinder. Other than that it's a very nice straight shot..... just like the Hemis of old. The intakes are very nice, other than some casting flash. I took pics of the intake and exhaust ports as well as the combustion chamber layout. Once I get the pics developed, I'll post them so people know what I'm talking about.
As far as letting people know what works..... I've always been pretty free with my info (even if it is mis-guided) hahahaha

You're single! Your livin' my fantasy in more ways then one-DON'T tell the ole' lady! HAHAHA! The cheapo lakewoods totally killed the wheel hop-for $29 you can't go wrong It would be interesting to see how it compared to the roadmaster set up.

The dealer being able to get rid of the speed limiter is all a bad rumor. There are no flashes for this and nothing I can do to eliminate it other than unplug the rear speed sensor. I have talked to chrysler technical assistance and have asked 2 different guys, no go. If I could I would eliminate the speed limiter on mine as well but I have the 117 limiter so it doesn't get hit often.
