6.1 Cam
 

Hey where can i order a 6.1 cam. I'm gonna do a cam swap on my o6 dodge 1500 57 hemi

Henson motor sports in Tex has the best price. Ask for Art in the parts department
1800-530-5337.

You have MDS right? You can't use the 6.1 cam without replaceing the lifters and deleteing the mds option from the pcm. OR,, I'll check but I believe you can ground out the selenoid signal and put the non MDS plugs in the block. It involves removing the heads. So there's a little more to it.

How am i supposed to tune it out. Theres no one around here that tunes dodge...

That's whats nice about a 6.1 cam, no tuning required.

Hmmm, sounds like a plan amigo

I have seen a couple on ebay for about $200-215....might start there.

Call Art, He sells them for around 130 I think.

But like I said, You have MDS. You'll have to get around that.

Fuck ebay. Yes i'll give art a call very soon. Now i just have to get someone to tell me how to disable MDS. The thing is, dont the 6.1 Litre cars have MDS as well???

6.1L cars don't have MDS...

Mother of God.......... What in the hell. Wait, how does the MDS even make a difference

The MDS lifter will not tollerate over .500 valve lift.

You can get a flash from B&G to delete MDS. Or ground out the selenoid and replace it with the block plug from the 03-05 truck engines

Where is the selenoid located. Block plug?

Under the intake manifold in the cam valley.

Stop the Madness!
 

I can answer most all of this...........

#1. No, the 6.1 cam does not require tuning......its a plug-n-play
#2. Yes, they are cheap..........I can get you a used one even cheaper
#3. The MDS motors will allow MORE than .500 lift ie. the Comp XFI260
#4. You can "ground out the MDS" but it will throw a CEL
#5. Call Dave @ B&G and ask him about a computer flash
#6. OR run the Comp XFI260 and not tune it and still have MDS

If you have any questions I'd be happy to help.

What cam options are there for the 6.1, with the available tuning options?

Steve and I are not supporting vendors YET, but are talking about it.

Comp offers 3 and so does Crane.

Steve and I offer a few...........

Tuning for the LX's (cars) seems to be monopolized by B&G, but there are rumors of stuff coming out this first quarter. The biggest tuning options we need are:

- raised idle rpm
- adj timing both static and tip in
- fine adj of the MAP
- depletion of the MDS mode from the appropriate vehicals

I think I was misunderstood. The MDS lifter performs poorly over .500 lift and 5000 rpm. Will it run fine lower in the rpm range, yes. But why do it if you will have issues.

will run fine at rpm limit. i dont know where that info is coming from but its been proven time and time again. the theory was at one point max lift would be .518. that like i said was proven wrong and the comp xfi 260 cam runs fine. even with the stock spring. it does run better with the comp 918 tho.

i have some grings for the 6.1 and the 5.7. but im not comfortable selling here as we are not vendors. maybe soon.

steve

Ok so it runs better with the comp spring. That tells me the stock spring is overloaded with the mds/heavier lifter. So why would you risk running the bigger cams with stock springs or mds lifters.

Denny

not saying thats how i would run mine or yours. just saying that it has been done. i agree the lifter itself needs to be removed and replaced. but if your not ready to yank the head, then just install the comp spring and be done.

im all for lightweight valvetrain stuff. the mds lifter is a touch heavier than the other lifter, but not that much.

steve-o

the actual weight diff comes out to 4 grams extra for each mds lifter.

steve

Good info, Gremlinsteve, Can you email me with info of your business? Looking for cams and internal parts.

The MDS system uses different lifters from the 6.1L. You must use the 6.1 lifter with the 6.1L cam. All you have to do is disconnect the connecters on the deactivation solinoids to disable the MDS system. I remember seeing a company that was making port plugs for MDS blocks at SEMA but never grabbed any info.

or 5.7 truck lifters. all together the parts from mopar only run about 250$$$ thats with the head gaskets and bolts to go with it.

now, b&g can take the lx platforms computer and tune the mds out of it which isnt a bad thing either that way you get rid of all the little check lights and cel's that might pop up. i do not think that a mds cel will alter the way the car runs as some of the codes do.

steve-o

Sharadon.............not meaning to argue, just telling what we know.

Your statement was "will not tollerate"...........all we were doing is letting you know that wasn't true. Where the "spring" part of this conversation came from is beyond me.

MDS works fine in the .500 - .530 area.............some guys have MDS kicking in at 80-90 mph going down the freeway...........all thru efficiency; crazy stuff.

We do NOT advocate the use of the MDS period..........more, small moving parts that add to valve train weight.................but it does work over .500.

it does run better with the comp 918 tho.

This is were I got the spring statement from. I'm not trying to argue either just stating my opinion.

My statement (will not tolerate) Yes, I should have stated it differently. But If the valve train isn't operating properly your headed for trouble. So if you are using a bigger then stock cam why would you use stock springs or a MDS lifter. I don't.

Can it be done, sure it can. A lot of thing can be done that should'nt.

Just my opinion

not our test. i was just passing on info from some one in the country that actually tested the 260 comp with the stock spring. he drove the car for several weeks/months with the stock spring and stated that it ran fine.

he did upgrade to a comp 918 after that test and stated that the car did pick up some et at the track.

i would have done the spring and cam swap at the same time.

a 5.7 spring has about 86 lbs of seat. i forget the open pressure.

6.1 was about 100 if i remember right. maybe a 110. ill have to go back and look at my notes for that. it would be a cheaper upgrade in spring tho on the head.
even the ls6 gm spring will work. you will have to shorten the install height to a 1.750 tho to get seat pressure up a tad more.

steve

The cheap popular spring is the 6.1 exhaust spring. It's 130 on the seat and 330 open. The manley spring is 130 on the seat and 360 open. I think the comp spring is 125/300. They all work without issue. I never bothered to check the 5.7 spring.

Ok, well say i leave the MDS alone and JUST replace the lifters and cam with the 6.1 cam i priced for $130 at the dodge dealership. Shouldn't it be just fine?? And, what is the lift on the 6.1 cam?

no it won't be enough.............change the springs. Lift is in the 330-ish range

I have all the specs but not on me right this second................I'll look up later for you.

Lift at the valve is .540 Some have kept their 5.7 springs using the 6.1 cam. I don't recommend doing that. Sooner or later the 5.7 spring will fail. Not worth the gamble. Try to buy 2 sets of 6.1 exhaust springs. Or get the Manley springs.

You still have to deal with the MDS in the pcm.

Well then... KRC has a kit the converts MDS to non MDS for $250. Not including the "special programming" is this just clearing the CEL's? If so counldn't a superchips do that? Any how i'm gonna buy the conversion kit very soon.

go to your local deale and pick up a couple of the lifters for a 03-04 truck or the srt8 cars. non mds ones. a set of mds solenoid plugs, and the lifter holders. gaskets and head bolts to go with the removal of the heads and your about 250 bucks.

that still wont clear the mds from your computer. you will need a b&g tune for that.

steve

I don't see why you need MDS plugs.................just drop in the new lifters and call it a day...........

If you use the B&G it will stop seeing the MDS anyways.

B&G should be able to flash the MDS out of the 06 truck, the computer is basically the same one used in the LX platform with minor changes to the tables, or so I am told.

The KRC fix for MDS is the B&G flash, they just send your PCM to them.

I have run the 6.1 exhaust springs on my truck for a good while with no problems. They are cheap too!

I have also heard you can trick the MDS into not working by using thicker oil, grounding the oil temp sensor on the motor, and by leaving the soleniods attached and just zip tying them out of the way behind the motor somewhere. I have not tried any of these things, so don't hold me to them.

I'm not sure if it's safe to leave the soleniods in place once you eliminate MDS because I am not sure what the oiling is doing inside there, but they are a lot easier to remove than the plastic plugs if you ever have to take them back out! The non-MDS motors use different oil galley plugs in the block that have a longer reach than the MDS motors. I'm not sure if they block oil flow to where the soleniods go, but that's what it looks like? I don't think it would be an issue but it might?

I just don't know about all these little tricks... Sounds dangerous. If i'm gonna do it, I'm gonna do it right and just take the truck and have the conversion done at KRC. Might be a nice little vacation trip. Well... where is their shop? What state, i live in Arkansas.

We can have your truck put on a transport and delivered to MN. Many of our customers do it.

I would HIGHLY recommend you do a lot of research on KRC (or any shop for that matter) before you take them your truck, even for just an oil change. If you search on hemitruckclub.com, or dodgetruckworld.com you will see exactly what I am talking about.

I own The HEMI Shop in Austin, TX and we are less expensive and we have an outstanding reputation.

Sheradon Performance is also a great shop for HEMI stuff, we work on a lot of projects together, they are just a lot farther away from where you live.

The Hemi Shop and Sharadon are the north/south shops to go to. We work together hand in hand. Maybe we should start a franchise? :drive:

i would recomend either of those two shops too. hemi shop or the sharadon. go to moparts and do a search for krc. you will see what they are talking about.

plus dont forget, i specialize in top end work on these motors. heads, cams, intake work and timing gears.
but im also a disabled vet so i do not do installs any longer. and i would still recomend the hemi shop or sharadon.

The oil is just going thru its normal route unless MDS is kicked on.................if MDS kicks on, it robs oil to the lifters and they just don't lift.

Not dangerous.

Many cars are running a B&G with MDS written out with NOTHING done to the coils.............they are just sitting there.

These plugs are just an "add on sale"............

I, like my partner Steve, would recommend the HEMI SHOP...........I do not know the other gentalmen.

While Scott and I have our differences of oppinion on a couple of things, we agree on alot............one of these agreemtns is about KRC and that Marty clown! :jest: :turd: :jest:
