@@martinbuilt that's awesome, I'm about ready to do my father's 4.7 Dakota for him. A 75mm would be really nice on it. I scored a 08 intake manifold for him for 60 bucks.

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.
I've got two Grand Cherokees. 01 with 4.7 and an 05 with a 5.7 Hemi. They are both high milage and the 4.7 is a better engine by a pretty good margin. It's also just as fast despite being rated at 100 less hp.
You have to be joking, i went in my local machine shop the other day and there was these junk engines laying everywhere with holes in top of pistons on most of them where the valve seat fell out of the head. Never heard anyone say they were good engines lol. No offense, i hope yours last forever, i just would hate for you to get too far from home with it.
@@dreece2000 You didn't point out which generation of the 4.7 they were. My guess would be 1st gens. they had problems with valve seats. Gen II engines did not suffer with the problem and were the vast majority of the 4.7's used Dodge/Rams, Durango's, and Dakota's.. but dropping valve seats was not exclusive to the 4.7. Ford and Gm both had their share is nightmares with dropped valve seats, cracking, and so on (also includes those asian and euro products as well) until they got the recipe corrected.
@@dreece2000 Mines got 270,000 miles on it. Still tows and hauls great. These engines are far from being junk. Id take one of these over a 2v or 3v triton *any* day, and I'd even go as far as saying they are as good or better than their closest competition at the time, the 4.6 Ford Modular. Ive owned both. I didn't like being far from home in that stupid 4.6 Panther body. I had to keep spare ignition coils in the trunk and I was always chasing vacuum and intake leaks. It had a leaky injector that burned up both catalysts and left me on the highway. The 4.7 has been better in every way in my experience. No engine issues in all those miles.

Going to be doing valve seals on my 03 Durgano. I won't be messing with the cams, but this is an excellent guide for removal of the valve covers, rocker arms, and lash adjusters. Thank you!
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.
Thank you, I agree the 4.7 is underrated and has great potential. I have a 4.7 HO on the stand that I will be rebuilding with lots of goodies. Thanks for commenting.
Also another trick I had handy...I had a pair of real long bent nose needle nosed pliers that I got in a set from TSC real cheap and they work absolutely perfect for popping off the rocker arms
A while back you told me that if I was rebuilding my motor and had the heads off and was planning on doing HO cams, that i should go ahead and do the whole upgrade and put HO heads on as well... I searched for an HO motor ever since you said that, apparently these motors are very hard to find in my area...but TODAY I GOT THEM!!! In snow and heavy rain and a period of hale I worked my but off and got those heads HAHAHA I remember the power our Durango had with a stock 4.7l so I am extremely anxious to get this not back in my truck with these upgrades...I am also hoping to do the intake manifold from the 08 jeep and am working with a guy at Shapeways to get a special filter housing cover made so I can use the snout Style scoops on the hood of my Dakota for "ram air" Thank you so much for all of these videos...this is my first total engine rebuild and you have taught me so much and made this rebuild a breeze.
Ah well it happens...did we ever get actual numbers on the HO amd torque increases for this? Also was wondering if you would use the HO fuel injectors or the stock ones? (Mine is a 2000)
@@martinbuilt I recently purchased a 2003 dodge ram 1500 4.7 and it had a tick to it. I searched and searched Until i came across this very video. Thank you for providing such details. Changed my rocker arms, hydraulic lifters with no problem. What is your cash app. Or a way for me to support your channel.. Thanks
Martin, please provide the information on the updated rocker arms and lifters for the 4.7. I have a 01 Durango and the lifter are ticking at start up. Thanks and keep feeding us with good info.
I just finished doing my 04. Put 08 cams in while I was at it. If you're thinking about doing this I can highly recommend it. Be warned, it is quite tedious getting just the right lash clearance. And you cannot just make all the same length. I set the lash .0015 - .002 and the lengths of the solid adjusters varied from the shortest being 1.934" and the longest being 1.952". Also, the threads are not real fine so a little turn changes the length quite a bit, and also tightening the lock nut will have the length grow about .0005 Makes getting as close to possible to .0015 lash quite the chore. Well worth it though. Dead cold start and.....silence!! So nice not to hear the clatter on cold start not to mention how much smoother the idle is, and the bonus of a quite noticeable top end increase. UPDATE! My PCM decided to retire so I lashed the adjusters again, a couple started getting noisy again. When I checked them the .0015" lash grew to over .002, I also noticed on the base of those adjusters the wear marks were different than the rest of them. They showed localized heavy loading vs the consistent pattern on the bottoms of the ones that maintained the proper lash. My theory is the bottom of the bores the adjusters sit in are not machined very smooth, this was confirmed by looking in the bores. I think the constant pounding of the cam pushing the lash adjuster down during valve actuation pushes the lifter down with more force, not being a hyd cushion the bottom of the adjuster is very slightly flattening down the high peaks the bore cutter leaves in the bottom of the bore increasing the depth of the bore and requiring a lengthening of the adjuster to compensate for the increase in bore depth.
Well I commend you for your perseverance on the whole job,, it’s definitely a task!! I’ve contemplated trying to get more power out of my 4.7 Mitsubishi Duro Cross,, my situation is I need more power than I can get from headers and solid lifters!! I was given a nice RV and it’s just too much for the pickup to pull !!! My thoughts are since I don’t get any kinda mileage from the 4.7, I’ve a mind to just swap out the motor for a 5.7 Hemi and just install the HO components before installation!! I know it sounds good but I’m sure there’s a lot of hindrances the come with that line of thinking!!! But you did a great job,, thanks for the tips!!!
I recently installed the cams but not the adjustable lifters. I did buy OeM style replacements made by enginetech. The roller wheel in the rockers are the same as the cam lobe width whereas the mopar OEM are much narrower and in time will create a wear pattern on the lobes.
I have a 2005 Dakota and I’ve recently done new timing chains and head gaskets. That chain wedge tool will be ordered and in my tool box soon. Maybe those HO cams are in the future. Great video!!! Thanks P.S. word to the wise I ordered the timing chain master kit from rockauto and everything was good, but the sensor wheel on the passenger side was incorrect causing cam sensor code P0340 to show up on a scanner. I had to take the front of the engine off twice, because I didn’t notice the difference in that wheel. A 2005 Dakota has a N code and a J code and there’s the HO 4.7 so there was no choice in these two different vehicle codes. Pay attention to the VIN.
When ordering a timing chain set if you're PCM has 3 connectors it is a JTEC and if you have 4 connectors then it is an NGC these are the ways you tell the difference between the 2 Cam gears on the passenger side. Your 05 is definitely a NGC 4 connector PCM.
Hi Martin, I'm driving a '03 Dakota 4.7 of course. There's an '08 Durango at my pick-a-part. I want to do the modifications you mention on your channel, but my question is: should I take the heads off the pick-a-part vehicle, or just the cam shafts and rockers? Will the whole head be compatible with my older 4.7? Is there any difference between the '03 and '08 heads besides the spark plugs? TIA
Yeah there is some more differences in the 03 to 08 cylinder heads you would also need the exhaust manifold's, the fuel injectors and I would use the 08 coils and spark plug wires as well one other thing that would happen is you're gonna lose compression because the combustion chamber on the 08 is larger than the earlier models. The valves are the same size but the intake and exhaust ports are larger on the 08 I'm not sure what the actual end result would be as far as performance, fro. the loss of horsepower. You would also need the valve covers those are also different. I would just recommend grabbing the Cam shafts. Now if that was a good running engine at the salvage yard I would grab the whole thing and put that into your 03 and you would probably only have to do some exhaust modification. And a small wiring changes on the Ignition coils.
@@martinbuilt thanks for your input. I think I'm just going to go for the camshafts. How do I know if it was a good engine without getting too deep into it? The camshaft bearings will have some insight I suppose...
I noticed the min is now .002 and max .004 on the ones I just got. I was going to shoot for .003 but after hearing your comments at the end I'll go for .002 I wanted to add, I have an old Harley ironhead Sportster that uses a similar valve tappet as far as adjustment. They use a ball on both ends so a feeler gauge is out, they are adjusted by how much resistance spinning the pushrod gives. I have found when I get the right lash and then tighten the lock nut it changes oh so slightly the length of the tappet. I am finding this now doing these. On my Sportster I go slightly longer and the tightening of the locknut sneaks it down to the desired length, I found that method works pretty good doing these also. I am in Michigan, not as hot as LV, I used to live in Phoenix, but it is 90 and muggy right now. I am on my third one taking a break feeding the dogs right now.
I've got a 2013 Ram 1500 with a 4.7 and would be interested in doing this also. On a side note I immediately recognized my old neighborhood on your test drive 😃 I grew up in hendertucky!
@@DieselTechBryan personally I like the engine. I love going to pick a part and so far I've seen 2 4.7 s that were in there because of valve seat dropping. When I bought my Jeep the previous owner basically lied to me about any major engine repairs. And then I found out that one of the cylinder heads had been replaced I would imagine it was for that reason. I believe if you keep up on the oil changes and run a high quality engine oil in it that this engine will last you a long time.
Great video .great information. What is the name if the tool you use to lose tho bolt. And tied back. I know you say the name but i can't get it my language is Spanish.
Hey Martin, @ 30:00 you begin installing the solid lifters. I'm doing the same install on a v6. My question is what is the target height of the overall lifter. You mention just over 49mm. Using your first lifter as the example I want to know if you readjusted the lifter off camera or at a later date want to ask if you had to change its measurement
You will definitely need to make adjustments to the lifters. And if you ever install a reground camshaft that will also make a difference. I spent hours getting the right measurement. Sometimes you have to take one lifter in and out half a dozen times before you get it right.
@@martinbuilt thank you for the reply and for posting this video! I just finished installing the slc on the passenger side. I tried to keep it close to .002. I dont have any lock tight on hand so I'm calling it for now and heading to the store for some. I did start it with the new SL installed on the passenger side. I think it sounded great, and with the two types of lifters I couldn't tell a difference in noise volume between the two. I'm pleased with the lifters, although I'm not looking forward to removing them again just to dab lock tight on them, but that's how she goes some times. I'm 5 or 6 hours into it. Do you have any advice on how to apply the locktight?
@@martinbuilt again I really appreciate the response! Is there any concern reguarding the necessity of the locktight under the lock nut? Or can I get away with a dab on the outside top? I'd like to not have to reopen and readjust the lifters. Thanks Martin, I'm subscribed! Side note, have you had to readjust them since?
After you do your test fit you can split the difference from your feeler gauge and lenghten or shorten with your calipers until your right where you wanna be.
I think that using the plastic cutting boards for making that wedge may just work perfect. Would my 2003 3.7 Liberty be this same set up. It starts knocking after it warms up¿?¿‽
@@martinbuilt I'll give it a shot. I've dropped 2 fulcrums for no apparent reason. I think cams may be low. Already replaced lifters (hydraulic), so I want to go solid to control lash. Does this make sense? Thanks for your response.
Great job! Your video will help me out a lot. Getting ready to remove me 4.7L to replace all gasket and sensors . Both of my 2001 and 2000 Jeep grand Cherokee limited are not high outputs. Q’S. Are the high output head valves bigger? Looks like Vegas.?
Thank you I'm glad you like them and find them helpful. No the valves are the same size throughout the history of the 4.7 99 through 2013. Yes it is Las Vegas.

YOU make it look easy! Seems like you come across more HO motors used in Pick-A Part yards out there than we do here in Pennsylvania. I've been searching for a set of HO cams, or better still complete HO heads with cams to rebuild for my 2000 SLT Durango 4X4 I'm doing a mild refresh on. 150K on the clock, I've owned it since brand new, so this is preemptive, not because of any issues, other than rusted and broken exhaust manifold bolts and heat shields. Would you be interested is selling a set of HO cams or dare I ask heads? Again I only ask as they seem scarce as Hens teeth here. Having driven my HO 2002 Grand Cherokee Limited with the same gears, I want the extra HO power for my Durango as well. What a difference, feels like a lot more than 30 horsepower, though the Durango is heavier than the 02 GC, but the gears are the same. Was toying with putting 3:92's in the Durango as well with the cams and a tune.
Hello Phil, All of the Durango I've seen so far all have 355 gears in them it would be nice to find a set of 392 that is the same gear I would like to install in my Dakota. The grand Cherokees with the 4.7 as far as I know all came with 373 pretty good gear, even though I may change those out to 392 possibly 411. I do have a set of HO cams available if you like to contact me on my Facebook Messenger there is a link in the description.
Hey, martin I have a 4.7 crank no start...CPU says the PCM is good. I have changed the camshaft, crankshaft, alternator, battery, Map sensor..also I hear the fuel pump engage when I prime it, there is also pressure in the line and it occasionally starts but dies right out. I started doing the work because I found out the mechanic was just a parts changer robbing me. please help, thanks
Nice vid! I have a 2007 Dodge Ram 1500 and a set of the ho cams. Could I simply just swap the cams without messing with the valves/lifters? I’m trying to decide whether or not I should take it to a shop. Thanks!
I cant tell you how much your videos helped with some nagging issues. Especially the anti-sludge piece. Solved a severe smoking issue and oil burning. Turns out you were right I was using the low end donkeyToy branded (?) Unit $17 dollars. What could go wrong? Plenty as it turns out. The $70 Standard Part 2008 unit was just the ticket. 👍
I finally found some HO camshafts. Been looking for 2 years, used online for like $200 and new... no one can find them. If put a HO jeep into any parts website they give same dimensions for the standard cam size in a regular jeep. Anyways I found a set at a junkyard, got them for $40!
Martin, I know this is an older video. Wondering how you liked the solid “lifters”. They every come loose on you or need adjustment? Last winter I ordered, then waited for Melling brand lash adjusters to come in because I believed them to be a good brand. They are now not staying pumped up. Might even have one or to not fully pumping up ever. It’s only been 7k miles. No dirty oil in the crank case, probably every, previous owner was meticulous. Didn’t see caked oil or dirty anything when installing HO cams. All the noises went away after replacement, first time I hammered on the truck the tick came back and hasn’t left. Not sure I wanna go solid lifters. Any other brands you recommend if they won’t replace these for me(and they prob won’t, it’s been a year even if only 7k miles)? Thanks for all you do Martin
Thanks for the great descriptive video. I have a few questions. Do you have to use solid lifters when you install HO camshafts? How has the Jeep been running since you put in the HO cams? will this upgrade cause a check engine light to come on? Will it affect smog checks (CA resident here). I have to replace my head gaskets on my '03 Ram 1500 with the 4.7L soon and I'm thinking about going all in and doing everything from timing chain to this HO cam upgrade. Thanks.
unusual to see the lobes scored if the bearing surfaces on the camshaft are scored that is somewhat common depending on frequent oil changes or not. If one of the rockers fell off and that's why you are changing the lifters and it did some damage to the cam and yes I would probably change that out.
You make this look too easy! This is Excellent! I read your introductory comments, what are the advantages of using solid lift vs. stock (I'm assuming hydraulic) lifters? At some point I would love to do this to my 2006 jeep commander 4.7
The solid lifters have a few advantages a higher RPM potential especially if you're into a lot of horsepower modifications. You'll never have a lifter collapse like you will with hydraulic. No she you're not into having to pull your valve covers off every 20000 mi in readjusting them then I wouldn't recommend them.
What if you measure the valve clearance before taking off the old rockers and lifters and couldn’t get any of them to slide in between? Tried all between .002 to .004 and nothing fit in between old the rockers and lifters
The old lash adjusters are hydraulic. There should be no Clarence at all with them. You need to install your rockers and solid lash adjusters and then check the clearance and make adjustments by removing them. It takes hours to get the adjustment correct. I would try to get it down to 002. If you settle at .004, you're going to have a noisy engine. When I do the adjustments, I get it all down, too .0015 Because, as the engine warms up, the gap actually grows between between valve stem and rocker tip.

Thank you, you can use the stock hydraulic lifters and you can install the HO heads on a non HO engine. Yes use your stock cam gear if you are installing this on a NGC 4 plug ECM.
Hey Martin, is there anyway you sell a cam sprocket wrench you made? I can’t get my cams out at all… I tried using a clap and it just slid.. darn bolts on there so tight it’s insane. I don’t have the stuff to make a sprocket wrench myself and can’t find anything at the local shops in my town.
I wrench on my own vehicle because frankly not many mechanics know what they are doing. I would have no problem in handing Martin my keys and say have fun... Or I'd even be with him working on it. He knows what he's doing and not many people that wrench on vehicles actually do.
@@martinbuilt Thank you very much for answering :) The thing is,i bought a 2002 gc overland in mint condition but it sadly had some dropped valve seats.Was thinking of putting on non ho heads with my cams since the ho heads are hard to find.Should work pretty well i think?
@@martinbuilt Thanks YOU so much... I'm considering to get this solid lifters because I'm sick and Tired of replacing the hydraulic lifters don't matter the brand I get they always fail sooner than later. The only issue I see with these solid lifters is that we have to readjust the gap if ticking re-apperas after a while so I don't know if that would happen in the same time frame as when the hydraulic lifters fail or it should never bother for a longer time than the hydraulic ones

Yeah you can get away with the stock Springs. With all your modifications that you've added or are going to add you may want to go with the Comp Cam Springs I think I have the part number listed in the description.
I have a 2003 Dodge Ram 1500 with the 4.7l in it. Can this be done to any 4.7l Chrysler engine? Does upgrading to HO cams mess with emissions (I'm in California) ? Any check engine lights come on? Great video by the way.
Thank you Antonio, yes you can do this to any Chrysler 4.7 that has a single spark plug per cylinder, that would be all before 2008. I know this will not interfere with the emissions and you will have no problems passing California smog.
On the 2nd coil pack from the front there is a sensor that is attached to the bolt...my 2000 Dodge Dakota has those but they arent hooked up...what are they?
Martinbuilt: question please: which is considered left side the drivers or passenger side. I downloaded service manual and I have a Haynes manual they are conflicting with which is left/right. Can you help me decide the correct side ( is it from sitting in drivers seat) or looking straight at the front of jeep outside ? I Just purchased the wedge using your link hope it helps your site out. Thank you Martinbuilt!
I've always considered the left side, Like if you were sitting in the vehicle. When it comes to rotating the engine clockwise then it's always as if you were standing in front of the engine facing it.
I have a 2004 4.7 h o Jeep Grand Cherokee. My question is if I pull out a camshaft from the 08 Durangos will it increase the horsepower or should I just stick with the stock 4.7 H.O camshaft? And if I do need to pull out a camshaft from a Durango which model do you suggest?
It should increase power but may change the torque curve or when you feel the power. I would also install the 08+ intake manifold with a larger throttle body. My Jeep Grand the power really kicks in at 3200 past 6000 RPM Any of the 08-13 Jeep, Dodge 4.7 engines with dual spark plugs per cylinder will work.
That's fine the ones you have are a OEM style lifter (latch adjuster). I would just soak them in oil for at least half an hour if not a couple hours before installing them. The adjustable latch adjusters I installed are great for reground high performance camshafts or if you're just wanting to get that extra edge of performance.
Thank you, I really appreciate that. I'm glad you liked it and found to helpful. no, you can keep the OEM lash adjusters. I just decided to go with the solids. I like the 08 cam shafts, But I would recommend also the 08 intake manifold and a larger throttle body with those camshafts and a very free flowing exhaust system.
The best benefit is that you never have to worry about a collapsed lash adjuster. You also have a higher RPM potential. Which in turn gives you more horse power. The disadvantage is that they are very time-consuming to get them adjusted properly.
You do great expiations as to the parts and the tools needed. Question MartinBuilt: Is their any issues using HO pistons, connecting rods with bearings, HO heads, intake manifold, HO cams into a 4.7 regular 8th digit N. Not changing crankcase due to tone ring i will use my normal cam tone ring. I ask because you do know alot of tricks on these 4.7 and the jeep grand cherokee
No there would be no issues doing that, you may want to just change the tone ring on the HO engine to a 32 tooth and the right cam sprocket to work with your vehicle and that way you also get the steel crankshaft.
Martinbuilt i may do that. Thank you for the fast reply and solid information. Was wondering if the tone ring was interchange. To correct ya take off the 32 tooth and replace with original 16 tooth tone ring...
If you're using hydraulic lach Adjusters you do not need to check clearances. If you're using the solid lash Adjusters when changing camshaft you will need to check clearance.
John Blair no I don't. I was actually working on a video for that and then after I saw some of the footage I just threw it away it wasn't any good. I got them off of eBay if you just look up battery terminals for audio you should be able to find them.
Yes I watched the video before and again right now. It’s the numbers on mine that make me wonder if I have the correct cam for the right side ? 141.3C over 13299
Great video! I bought my Jeep on the cheap cause the 4.7 had been cooked. The lifters were seized but I freed them up with acetone. But since getting her going again I noticed the lifters are noisy so I'm guessing they are worn out. So should I buy replacements solid lifters or factory?
Jason Zaicos I think I would just go ahead and buy hydraulic replacements. Unless you're going to be doing mods in the future and looking for more horsepower than go with the solids.
martinbuilt, ok then. I can't get head around why they are noisy. Its just annoying listening to them. Thanks for your reply. Your jeep sounds sweet by the way.
Engine too full of oil Engine low on oil Cylinder head drain back holes are clogged Valve stem seals are worn out Broken piston oil control ring Plugged crankcase ventilation, PCV Excessive piston ring clearness or scratched cylinder walls.
Yes it will bolt right on. Does your 06 have a EGR valve on the one cylinder head? If so you'll have to come up with some way of deleting the EGR. Or it may be possible to drill the HO to accept an EGR valve
can you replace the valve stem seals without taking the cam off? i got some blue smoke after i sit at a redlight then gas it to go. none at start up tho. but i do have some lifter noise at startup. so i was thinking of replacing the lifters and stem seals to see if that would solve the two issues.
martinbuilt I also was thinking about trying that, but im not real sure how hard it would be to make everything work with the dual spark plug setup and ecu stuff? Have you found any good reference information anywhere online? And can you measure your timing chain wedge for me so i can make one? I have to pull the right head on my ho wj later today? I was considering making a wedge for the tensioners, but i dont know what the correct dimensions would be.

I've got two Grand Cherokees. 01 with 4.7 and an 05 with a 5.7 Hemi. They are both high milage and the 4.7 is a better engine by a pretty good margin. It's also just as fast despite being rated at 100 less hp.
You have to be joking, i went in my local machine shop the other day and there was these junk engines laying everywhere with holes in top of pistons on most of them where the valve seat fell out of the head. Never heard anyone say they were good engines lol. No offense, i hope yours last forever, i just would hate for you to get too far from home with it.
@@dreece2000 You didn't point out which generation of the 4.7 they were. My guess would be 1st gens. they had problems with valve seats. Gen II engines did not suffer with the problem and were the vast majority of the 4.7's used Dodge/Rams, Durango's, and Dakota's.. but dropping valve seats was not exclusive to the 4.7. Ford and Gm both had their share is nightmares with dropped valve seats, cracking, and so on (also includes those asian and euro products as well) until they got the recipe corrected.
@@dreece2000 Mines got 270,000 miles on it. Still tows and hauls great. These engines are far from being junk. Id take one of these over a 2v or 3v triton *any* day, and I'd even go as far as saying they are as good or better than their closest competition at the time, the 4.6 Ford Modular. Ive owned both. I didn't like being far from home in that stupid 4.6 Panther body. I had to keep spare ignition coils in the trunk and I was always chasing vacuum and intake leaks. It had a leaky injector that burned up both catalysts and left me on the highway. The 4.7 has been better in every way in my experience. No engine issues in all those miles.
Great Video Man!! Love the detail and how descriptive it was! Now I’m considering doing this to my 02’ Dodge Dakota 4.7
Where do I find Mopar cams for the same vehicle
From any 2002 2003 and 2004 Jeep Grand Cherokee limited or overland with the j code. the 8th digit in the VIN number needs to be a j@@peytonthepianoman
Going to be doing valve seals on my 03 Durgano. I won't be messing with the cams, but this is an excellent guide for removal of the valve covers, rocker arms, and lash adjusters. Thank you!
Glad it helped
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.
Thank you, I agree the 4.7 is underrated and has great potential. I have a 4.7 HO on the stand that I will be rebuilding with lots of goodies. Thanks for commenting.
This was a very easy to listen to guy ,very detailed & clear instruction ,Great job on this video, Guy!
Thank you I'm glad you liked it and found it helpful.
Also another trick I had handy...I had a pair of real long bent nose needle nosed pliers that I got in a set from TSC real cheap and they work absolutely perfect for popping off the rocker arms
Yeah I can see where that would work well.
I tried it at the junk yard before I tried it on mine...worked wonderfully...and since they are long and bent nose, they work for reassembly too
A while back you told me that if I was rebuilding my motor and had the heads off and was planning on doing HO cams, that i should go ahead and do the whole upgrade and put HO heads on as well...
I searched for an HO motor ever since you said that, apparently these motors are very hard to find in my area...but TODAY I GOT THEM!!! In snow and heavy rain and a period of hale I worked my but off and got those heads HAHAHA
I remember the power our Durango had with a stock 4.7l so I am extremely anxious to get this not back in my truck with these upgrades...I am also hoping to do the intake manifold from the 08 jeep and am working with a guy at Shapeways to get a special filter housing cover made so I can use the snout Style scoops on the hood of my Dakota for "ram air"
Thank you so much for all of these videos...this is my first total engine rebuild and you have taught me so much and made this rebuild a breeze.
That's awesome that you found a set of heads. sucks it was in crapy weather.
Ah well it happens...did we ever get actual numbers on the HO amd torque increases for this? Also was wondering if you would use the HO fuel injectors or the stock ones? (Mine is a 2000)

I just finished doing my 04. Put 08 cams in while I was at it. If you're thinking about doing this I can highly recommend it. Be warned, it is quite tedious getting just the right lash clearance. And you cannot just make all the same length. I set the lash .0015 - .002 and the lengths of the solid adjusters varied from the shortest being 1.934" and the longest being 1.952". Also, the threads are not real fine so a little turn changes the length quite a bit, and also tightening the lock nut will have the length grow about .0005 Makes getting as close to possible to .0015 lash quite the chore. Well worth it though. Dead cold start and.....silence!! So nice not to hear the clatter on cold start not to mention how much smoother the idle is, and the bonus of a quite noticeable top end increase.
UPDATE! My PCM decided to retire so I lashed the adjusters again, a couple started getting noisy again. When I checked them the .0015" lash grew to over .002, I also noticed on the base of those adjusters the wear marks were different than the rest of them. They showed localized heavy loading vs the consistent pattern on the bottoms of the ones that maintained the proper lash. My theory is the bottom of the bores the adjusters sit in are not machined very smooth, this was confirmed by looking in the bores. I think the constant pounding of the cam pushing the lash adjuster down during valve actuation pushes the lifter down with more force, not being a hyd cushion the bottom of the adjuster is very slightly flattening down the high peaks the bore cutter leaves in the bottom of the bore increasing the depth of the bore and requiring a lengthening of the adjuster to compensate for the increase in bore depth.
Way to go, Charlie, couldn't have said it better myself.
Well I commend you for your perseverance on the whole job,, it’s definitely a task!! I’ve contemplated trying to get more power out of my 4.7 Mitsubishi Duro Cross,, my situation is I need more power than I can get from headers and solid lifters!! I was given a nice RV and it’s just too much for the pickup to pull !!! My thoughts are since I don’t get any kinda mileage from the 4.7, I’ve a mind to just swap out the motor for a 5.7 Hemi and just install the HO components before installation!! I know it sounds good but I’m sure there’s a lot of hindrances the come with that line of thinking!!! But you did a great job,, thanks for the tips!!!
I recently installed the cams but not the adjustable lifters. I did buy OeM style replacements made by enginetech. The roller wheel in the rockers are the same as the cam lobe width whereas the mopar OEM are much narrower and in time will create a wear pattern on the lobes.
installed HO cams in my 2001 durango today and your video was very helpful! keep up the good work boss
That awesome!
Did it add any noticeable power or no? Looking to do it on my 04.

@@brad3139 could you post a vid of it,looking to cam my 02 durango
I have a 2005 Dakota and I’ve recently done new timing chains and head gaskets. That chain wedge tool will be ordered and in my tool box soon. Maybe those HO cams are in the future. Great video!!! Thanks
P.S. word to the wise
I ordered the timing chain master kit from rockauto and everything was good, but the sensor wheel on the passenger side was incorrect causing cam sensor code P0340 to show up on a scanner. I had to take the front of the engine off twice, because I didn’t notice the difference in that wheel. A 2005 Dakota has a N code and a J code and there’s the HO 4.7 so there was no choice in these two different vehicle codes. Pay attention to the VIN.
When ordering a timing chain set if you're PCM has 3 connectors it is a JTEC and if you have 4 connectors then it is an NGC these are the ways you tell the difference between the 2 Cam gears on the passenger side. Your 05 is definitely a NGC 4 connector PCM.
Again,, great video !!! I forgot to ask in my recent comment the question, what 4.7 motor comes stock with the solid lifters and roller cam!!!
Hi Martin, I'm driving a '03 Dakota 4.7 of course. There's an '08 Durango at my pick-a-part. I want to do the modifications you mention on your channel, but my question is: should I take the heads off the pick-a-part vehicle, or just the cam shafts and rockers? Will the whole head be compatible with my older 4.7? Is there any difference between the '03 and '08 heads besides the spark plugs? TIA
Yeah there is some more differences in the 03 to 08 cylinder heads you would also need the exhaust manifold's, the fuel injectors and I would use the 08 coils and spark plug wires as well
one other thing that would happen is you're gonna lose compression because the combustion chamber on the 08 is larger than the earlier models.
The valves are the same size but the intake and exhaust ports are larger on the 08 I'm not sure what the actual end result would be as far as performance, fro. the loss of horsepower.
You would also need the valve covers those are also different.
I would just recommend grabbing the Cam shafts.
Now if that was a good running engine at the salvage yard I would grab the whole thing and put that into your 03 and you would probably only have to do some exhaust modification. And a small wiring changes on the Ignition coils.
@@martinbuilt thanks for your input. I think I'm just going to go for the camshafts. How do I know if it was a good engine without getting too deep into it? The camshaft bearings will have some insight I suppose...
Very informative and tru blessing to run cross this. I was wondering how a cam swap would go.
I’m replacing my bad lifters and rocker arms.
Would
I noticed the min is now .002 and max .004 on the ones I just got. I was going to shoot for .003 but after hearing your comments at the end I'll go for .002 I wanted to add, I have an old Harley ironhead Sportster that uses a similar valve tappet as far as adjustment. They use a ball on both ends so a feeler gauge is out, they are adjusted by how much resistance spinning the pushrod gives. I have found when I get the right lash and then tighten the lock nut it changes oh so slightly the length of the tappet. I am finding this now doing these. On my Sportster I go slightly longer and the tightening of the locknut sneaks it down to the desired length, I found that method works pretty good doing these also. I am in Michigan, not as hot as LV, I used to live in Phoenix, but it is 90 and muggy right now. I am on my third one taking a break feeding the dogs right now.
yea I like .0015 to .002
I've got a 2013 Ram 1500 with a 4.7 and would be interested in doing this also. On a side note I immediately recognized my old neighborhood on your test drive 😃
I grew up in hendertucky!
Are you still in the Vegas area? Your 2013 has better cams then the HO's. I will be installing the 2008+ cams soon with the HO springs.
@@martinbuilt Ok, this is the first 4.7 I've had. Are these a pretty good engine longevity wise? I've heard things about them dropping valve seats?
@@martinbuilt Yes, still in Vegas too
@@DieselTechBryan personally I like the engine. I love going to pick a part and so far I've seen 2 4.7 s that were in there because of valve seat dropping. When I bought my Jeep the previous owner basically lied to me about any major engine repairs. And then I found out that one of the cylinder heads had been replaced I would imagine it was for that reason. I believe if you keep up on the oil changes and run a high quality engine oil in it that this engine will last you a long time.

Nicely done. Butterflies in your gut when your loosening the cam bolt. I know the feeling. Thank you.
I have a 2006 4.7 grand Cherokee can I install the ho cams as well
Hey Martin, @ 30:00 you begin installing the solid lifters. I'm doing the same install on a v6. My question is what is the target height of the overall lifter. You mention just over 49mm. Using your first lifter as the example I want to know if you readjusted the lifter off camera or at a later date want to ask if you had to change its measurement
You will definitely need to make adjustments to the lifters. And if you ever install a reground camshaft that will also make a difference. I spent hours getting the right measurement. Sometimes you have to take one lifter in and out half a dozen times before you get it right.
@@martinbuilt thank you for the reply and for posting this video! I just finished installing the slc on the passenger side. I tried to keep it close to .002. I dont have any lock tight on hand so I'm calling it for now and heading to the store for some. I did start it with the new SL installed on the passenger side. I think it sounded great, and with the two types of lifters I couldn't tell a difference in noise volume between the two. I'm pleased with the lifters, although I'm not looking forward to removing them again just to dab lock tight on them, but that's how she goes some times. I'm 5 or 6 hours into it. Do you have any advice on how to apply the locktight?
I actually did not do any Loctite on mine. I would remove them clean them up and place one drop or 2 at the threaded part.
@@martinbuilt again I really appreciate the response! Is there any concern reguarding the necessity of the locktight under the lock nut? Or can I get away with a dab on the outside top? I'd like to not have to reopen and readjust the lifters. Thanks Martin, I'm subscribed! Side note, have you had to readjust them since?
@@alexbrown8997 I would just a dab on the nut. No I haven't had to adjust them. Hopping to install the 08 camshafts soon.
After you do your test fit you can split the difference from your feeler gauge and lenghten or shorten with your calipers until your right where you wanna be.
After watching your video, I think I could do this, I have a couple other little projects first but I could definitely work this out for next year😁
Thanks I'm glad you liked it and found it helpful and gave you the confidence that you could do this. 😊
I think that using the plastic cutting boards for making that wedge may just work perfect. Would my 2003 3.7 Liberty be this same set up. It starts knocking after it warms up¿?¿‽

YOU make it look easy! Seems like you come across more HO motors used in Pick-A Part yards out there than we do here in Pennsylvania. I've been searching for a set of HO cams, or better still complete HO heads with cams to rebuild for my 2000 SLT Durango 4X4 I'm doing a mild refresh on. 150K on the clock, I've owned it since brand new, so this is preemptive, not because of any issues, other than rusted and broken exhaust manifold bolts and heat shields. Would you be interested is selling a set of HO cams or dare I ask heads? Again I only ask as they seem scarce as Hens teeth here. Having driven my HO 2002 Grand Cherokee Limited with the same gears, I want the extra HO power for my Durango as well. What a difference, feels like a lot more than 30 horsepower, though the Durango is heavier than the 02 GC, but the gears are the same. Was toying with putting 3:92's in the Durango as well with the cams and a tune.
Hello Phil, All of the Durango I've seen so far all have 355 gears in them it would be nice to find a set of 392 that is the same gear I would like to install in my Dakota.
The grand Cherokees with the 4.7 as far as I know all came with 373 pretty good gear, even though I may change those out to 392 possibly 411.

New HO cams? Excellent price for the junkyard ones at $40
What's the best kind of spark plugs to put in the 4.7. And all so the coil packs.
Why don't you take the cam shaft off before the rockers? It seems like the rockers would just come right off as you are loosening the cam shaft bolts.
Martin, I know this is an older video. Wondering how you liked the solid “lifters”. They every come loose on you or need adjustment?
Last winter I ordered, then waited for Melling brand lash adjusters to come in because I believed them to be a good brand. They are now not staying pumped up. Might even have one or to not fully pumping up ever. It’s only been 7k miles. No dirty oil in the crank case, probably every, previous owner was meticulous. Didn’t see caked oil or dirty anything when installing HO cams.
All the noises went away after replacement, first time I hammered on the truck the tick came back and hasn’t left.
Not sure I wanna go solid lifters. Any other brands you recommend if they won’t replace these for me(and they prob won’t, it’s been a year even if only 7k miles)?
Thanks for all you do Martin
I like the solids but they are a lot of work to adjust them. I haven't had to adjust them since installed. If you do go solids tell Nick I sent you.
Are all the lifters and rockers the same? As in, do they need to go back in the same order? Thanks
Thanks for the great descriptive video. I have a few questions. Do you have to use solid lifters when you install HO camshafts? How has the Jeep been running since you put in the HO cams? will this upgrade cause a check engine light to come on? Will it affect smog checks (CA resident here). I have to replace my head gaskets on my '03 Ram 1500 with the 4.7L soon and I'm thinking about going all in and doing everything from timing chain to this HO cam upgrade. Thanks.
You don't need the solid lifters. It will not cause any checks light and no problem with CA smog.
@@martinbuilt Thank you for the speedy reply Martin.
Should I replace cam along with lifters if cam lobes are slightly scored?
unusual to see the lobes scored if the bearing surfaces on the camshaft are scored that is somewhat common depending on frequent oil changes or not.
If one of the rockers fell off and that's why you are changing the lifters and it did some damage to the cam and yes I would probably change that out.
Hey Martin, can the heads be removed/installed without removing the cams?
Yes
You make this look too easy! This is Excellent! I read your introductory comments, what are the advantages of using solid lift vs. stock (I'm assuming hydraulic) lifters? At some point I would love to do this to my 2006 jeep commander 4.7
The solid lifters have a few advantages a higher RPM potential especially if you're into a lot of horsepower modifications. You'll never have a lifter collapse like you will with hydraulic. No she you're not into having to pull your valve covers off every 20000 mi in readjusting them then I wouldn't recommend them.
Is there a difference in the left and right cam.
What if you measure the valve clearance before taking off the old rockers and lifters and couldn’t get any of them to slide in between? Tried all between .002 to .004 and nothing fit in between old the rockers and lifters
The old lash adjusters are hydraulic. There should be no Clarence at all with them. You need to install your rockers and solid lash adjusters and then check the clearance and make adjustments by removing them.
It takes hours to get the adjustment correct. I would try to get it down to 002. If you settle at .004, you're going to have a noisy engine.
When I do the adjustments, I get it all down, too .0015
Because, as the engine warms up, the gap actually grows between between valve stem and rocker tip.

Great video!!!! but I have a question wouldn't it run better if you installed a 4.7 HO intake to match the cams??

Thank you Antonio, yes you can do this to any Chrysler 4.7 that has a single spark plug per cylinder, that would be all before 2008. I know this will not interfere with the emissions and you will have no problems passing California smog.
On the 2nd coil pack from the front there is a sensor that is attached to the bolt...my 2000 Dodge Dakota has those but they arent hooked up...what are they?
It is a capacitor for the ignition coils. I would hook them back up
Martinbuilt: question please: which is considered left side the drivers or passenger side. I downloaded service manual and I have a Haynes manual they are conflicting with which is left/right. Can you help me decide the correct side ( is it from sitting in drivers seat) or looking straight at the front of jeep outside ? I Just purchased the wedge using your link hope it helps your site out. Thank you Martinbuilt!
I've always considered the left side, Like if you were sitting in the vehicle.
When it comes to rotating the engine clockwise then it's always as if you were standing in front of the engine facing it.
Thank you for your quick reply. Always the best videos and information on the web.
I have a 2004 4.7 h o Jeep Grand Cherokee. My question is if I pull out a camshaft from the 08 Durangos will it increase the horsepower or should I just stick with the stock 4.7 H.O camshaft? And if I do need to pull out a camshaft from a Durango which model do you suggest?
It should increase power but may change the torque curve or when you feel the power. I would also install the 08+ intake manifold with a larger throttle body. My Jeep Grand the power really kicks in at 3200 past 6000 RPM
Any of the 08-13 Jeep, Dodge 4.7 engines with dual spark plugs per cylinder will work.
@@martinbuilt just checking... Does it have to be from the years 08-13, and only from the dodge and jeep 4.7 engines??
@@noemah3272
yeah all the 08-13 Chrysler, Jeep and Dodge 4.7 engines. These engines will have dual spark plugs per cylinder.
Hello. Thank you for the explanation, i am on to this now but what it the lifters that i bought do not come with any adjusting at all..
That's fine the ones you have are a OEM style lifter (latch adjuster). I would just soak them in oil for at least half an hour if not a couple hours before installing them. The adjustable latch adjusters I installed are great for reground high performance camshafts or if you're just wanting to get that extra edge of performance.
@@martinbuilt Great , i installed everything last night and worked like a charm thanks to you!
What exhaust manifold is that?
So if i put ho cams in, I have to switch to solid / adj lifters? By the was outstanding job! Which is the best cam, 04 ho or 08 cams?
Thank you, I really appreciate that. I'm glad you liked it and found to helpful. no, you can keep the OEM lash adjusters. I just decided to go with the solids.
I like the 08 cam shafts, But I would recommend also the 08 intake manifold and a larger throttle body with those camshafts and a very free flowing exhaust system.
@martinbuilt Is there a benefit to using the solid lashes adjusters over the hydraulic?
The best benefit is that you never have to worry about a collapsed lash adjuster.
You also have a higher RPM potential. Which in turn gives you more horse power.
The disadvantage is that they are very time-consuming to get them adjusted properly.
Greath job brother, you´re are an artist....!!!!!!
You do great expiations as to the parts and the tools needed.
Question MartinBuilt:
Is their any issues using HO pistons, connecting rods with bearings, HO heads, intake manifold, HO cams into a 4.7 regular 8th digit N. Not changing crankcase due to tone ring i will use my normal cam tone ring.
I ask because you do know alot of tricks on these 4.7 and the jeep grand cherokee
No there would be no issues doing that, you may want to just change the tone ring on the HO engine to a 32 tooth and the right cam sprocket to work with your vehicle and that way you also get the steel crankshaft.
Martinbuilt i may do that. Thank you for the fast reply and solid information. Was wondering if the tone ring was interchange. To correct ya take off the 32 tooth and replace with original 16 tooth tone ring...
Hey Martin, are you required to check clearances if you don't remove the camshaft, and are only replacing the lash adjusters and rockers? Thanks!
If you're using hydraulic lach Adjusters you do not need to check clearances. If you're using the solid lash Adjusters when changing camshaft you will need to check clearance.
@@martinbuilt Great thank you Martin. Take Care.
Do you have a video of installing those custom battery terminals? What kind of battery is that?
John Blair no I don't. I was actually working on a video for that and then after I saw some of the footage I just threw it away it wasn't any good. I got them off of eBay if you just look up battery terminals for audio you should be able to find them.
I am replacing the stock hydraulic/mechanical lifters. Do they need to soak in oil prior to install ?
I do not know if it is required , but I would soaked them for a couple hours
Can you use the stock lifters with the HO cams
Yes they are no different than the ones from the HO engines.
Two cams for HO 1. # 53021411ab left side…other # 141.3c over 13299 right side. Is right side cam correct number??? Thank you
That should be correct. Check out this video th-cam.com/video/UqSQ9QrCFro/w-d-xo.html
Yes I watched the video before and again right now.
It’s the numbers on mine that make me wonder if I have the correct cam for the right side ? 141.3C over 13299
Great video! I bought my Jeep on the cheap cause the 4.7 had been cooked. The lifters were seized but I freed them up with acetone. But since getting her going again I noticed the lifters are noisy so I'm guessing they are worn out. So should I buy replacements solid lifters or factory?
Jason Zaicos I think I would just go ahead and buy hydraulic replacements. Unless you're going to be doing mods in the future and looking for more horsepower than go with the solids.
martinbuilt, ok then. I can't get head around why they are noisy. Its just annoying listening to them. Thanks for your reply. Your jeep sounds sweet by the way.
Jason Zaicos they're not supposed to be noisy. If they are noisy they are either collapsing or you have weak valve springs
Jason Zaicos could be timing chain tensioners are starting to go
Roman Beck, has new timing chains. Just bought new lifters. I remember the existing lifters were very soft to depress. New ones are much stiffer
What if we are changing the heads? Same process?
If you're replacing the cylinder heads you're going to need to pull the front timing cover and redo the entire timing chain set.
good night martin do you know why it shoots blue smoke when accelerating the grand cherokke 2001
Engine too full of oil
Engine low on oil
Cylinder head drain back holes are clogged
Valve stem seals are worn out
Broken piston oil control ring
Plugged crankcase ventilation,
PCV
Excessive piston ring clearness or scratched cylinder walls.
Rings when smoking accelerating, valve seals when smoking de-accelerating.
@@charliedee9276 what rings are you talking about? My 04 jgc 4.7 h.o blue smoke when accelerating, no smoke when stopping, no smoke on idle
I found a 2004 HO 4.7L from a Jeep Grand Cherokee at a pick a part....Q: will the entire cylinder heads fit on a 2006 4.7L Jeep Commander?
Yes it will bolt right on. Does your 06 have a EGR valve on the one cylinder head? If so you'll have to come up with some way of deleting the EGR. Or it may be possible to drill the HO to accept an EGR valve
I have a 2003 dodge durango with the 4.7l v8 does anyone know where to find the cam bearing caps for the right bank ive looked everywhere i know of.
What would happen if you were to go over .004???
It would sound like a bunch of bad lash adjusters. Lots of ticking!
I’m replacing standard cams with HO in my 4.7. Do I need new lifters or can I leave the old ones in?
You can reuse the old ones.
Martin, have you given it thought?
Going to use this video to help me with lifters and rockers.
I’m going to be in your neck of the woods on the eighth and ninth to inspect a couple new bridges that are built. Here it’s going to be very hot.
Yes it is very hot It looks like it's going to be the hottest June on record.
can you replace the valve stem seals without taking the cam off? i got some blue smoke after i sit at a redlight then gas it to go. none at start up tho. but i do have some lifter noise at startup. so i was thinking of replacing the lifters and stem seals to see if that would solve the two issues.
Travis Flint****** Check your coolant level. ( may be leaking into cylinder )
if so then stop driving it NOW! PULL THE HEADS ( BOTH ) AND FIX IT.
NOW.
I've got a 08 4.7 Chrysler Aspen. I'm looking to add to it this summer. Where should I start? Stock.
That engine already has 304hp. Someday I hope to reach that. Lol. Maybe look into a cat back exhaust system.
martinbuilt that was my initial thought too. Supercharger?
Supercharger...Go for it! I have been thinking about swapping in a 08 or newer 4.7
martinbuilt I also was thinking about trying that, but im not real sure how hard it would be to make everything work with the dual spark plug setup and ecu stuff? Have you found any good reference information anywhere online? And can you measure your timing chain wedge for me so i can make one? I have to pull the right head on my ho wj later today? I was considering making a wedge for the tensioners, but i dont know what the correct dimensions would be.
