He's asking about juice lifters, Ron.
Not sure how much need there is for them, considering the relativly low spring pressures you run with a hydraulic cam. Not really needed IMO. Think about how much oil is already spilling down the valley directly onto the camshaft (if you've never seen it, its a LOT!!). Do you really think a tiny little hole is going to help or change anything? It's not lack of oil that causes cam failures. It's the wrong oil / lack of zinc additives in the oil that causes issues.
With the higher spring pressures of an extreme solid, I can see them as added insurance. Even then that's all they really are: added insurance. But on a hydraulic.... Wasted money IMO.

Yes mine a solid flat tappet but they are EDM lifters with the small hole in the bottom to lube the cam lobes. Ron

Meaning what exactly? They are available for Chevys so it's obviously doable... I don't mind spending extra for parts that some say is overkill, I'm well aware of ZDDP in oil, I've heard of enough mild hydraulic cams going flat that I'm willing to take extra measures to protect my cam & in turn protect my engine... I didn't ask if anyone thinks I need them, I asked if they are available & who sells them...

I think that is a misprint and those have a flat ground on the side to increase oil to the cam,old trick. Call Howard's and confirm would be my suggestion. Would be a trick but not sure the need to go to the effort.

I don't think that is a misprint as they are listed the same way on the howards site.
Randy , Crower sells a lifter called the CAM SAVER that has a flat ground on the side that dumps oil down. I put a set in a 440 with a comp nitride cam , so far so good , and I have a couple more sets I'm going to run.
Someone asked this question , I don't think there is a mopar/amc EDM liter.

Yeah. Howards says they use an "EDM" laser to drill a 0.021" hole to oil the cam.
First this is not true EDM and that's why they put it in quotes, just going for accuracy here.
Second, why use a laser to drill a hole and not a drillbit? That hole is one third the diameter of a 1/16 drillbit and I break about every other 1/16 bit that I use.

I am a bit skeptical regarding EDM hydraulics either their existance or the concept. First of all this is the first I've ever heard of the EDM concept being applied to hydraulics. I think the idea of sending pressurized oil directly to the lobe/lifter interface may have some merit, but where is the oil supposed to come from? As I see it, it can only come from one place and thats from inside the lifter body, I am not talking about lifters that use a groove on the outside of the lifter body here. Hydraulic lifters are made to very close internal tolerances. So close in fact that we are advised not to ever swap internals from one lifter to another. A .021 hole may not seem like much, but compared the internal clearances of a hydraulic lifter it's a bunch. I think a hole of that size will almost certainly have a deterimental effect on the lifter's ability to maintain proper preload and valve action ie. lift and duration. Something like the Rhoads and Crane lifters that were once sold with idea of quick bleed down at low rpm so that "hot" cams would be more streetable. In this case I think the bleed down would be a good deal greater. Of course I could be wrong about all this, but I know I am not going to be the first to try a set even if they do exist.

Re: Any one sell EDM Hydraulic lifters for Mopar? - 03/05/13 10:23 PM
I will say the hole in my Comp EDM lifters looks smaller then .021. Thats about what a dist point gap used to be and the hole in the bottom of mine do not look that big to me. To be honest they look small enough that I would think it would not effect the opperation of the hydraulic lifter. As long as the eng has good oil press and the lifter check valves are sealing good. But thats just my thought as I really dont know about the hydraulic ones as I have never looked into them. I do see the flat on the lifters shown where oil can bleed down to the lobe. Dwayne Porter actually got mine for me but they said Comp on the box. He also ground my cam and nitrided it. Ron

That is not the lifter in question but is the lifter I suggested and have used . I didn't do a comarision yet but be warned that is a AMC spec lifter also so it may require a different length pushrod , the engine I used it in had adjustable pushrods with stamped rockers .

Relatively sure no one cares at this point, but EDM
stands for "electrical discharge machining", saw one at one of my best friends' machine shop (they later sold it),It looked kinda like a drill press but lower, and had a holder where the chuck would be, and you used a specified size electrode and amperage(?) to burn a precision hole in metal.They used it IIRC to core a few broken studs and decided it wasn't a tool they would use often.

All I have seen from you is speculation of a misprint, nothing factual, just speculation.
The Crower lifters with the flat claim a 1-2 psi drop in oil pressure , how much oil pressure do you THINK is being lost between the cam and lobe that has the oil film as the amount of clearance?

What are you talking about ? what makes you so sure , you are still not answering the question that was asked of you .
That is the way I am reading you hieroglyphics on the subject, you have NEVER actually seen, purchased or talked to anyone . All you are doing is speculating.
Comp has found a bigger money maker , they nitride the cams at a cost of $150 ...
NO I don't need to handle one to know whats going on,but maybe you do??? Nitriding a flat tappet is silly but I shouldn't say that on the net as some are still spending the $$$. 
You got it yet?

Summit shows the same picture of a lifter with a flat ground on the side as on the Howard site but for some reason did not copy the text from the Howard's site ?

I ordered a flat tappet cam today,no nitride,no oiling lifters . 160lbs seat 20lbs boost no worries. I'll let everyone know if it goes flat
Hopefully you didn't order something off the shelf from Comp because the last one I had only lasted 6 mins before it started going south

I have been lucky as I have never wiped a cam lobe. But with this oil we have now I started to worry a little when I built my 493. I went with a custom grind from Dwayne Porter who I consider one of the best head and cam guys out there. He recomended we nitride the cam which I did and that we go with the EDM solid lifters which I did. I also added a bottle of the ZDDP additive and use Valvoline racing oil which has a high content of ZDDP. And I left the inner springs off to break in the cam which is the first time I had ever done that. Everything has worked very good as after the cam broke in I reinstalled the inner springs which have 150 seat pressure closed. Nitriding the cam just seemed to make sense and made me worry less about wiping my first ever cam lobe which I have not had happen yet and if Dwayne Porter recomended it I felt it was worth it. Just thought I would let some know how my last cam break in went. Thats was in June 2011 when I put the eng in the car and it has run fine since then. Of course we all will have different ideas at times but thats why I like to listen to everyone as sometime you pick up and idea and think to yourself.......heck that might be a better idea then the way I do it.

The only cam company nitriding cams to my knowledge is Comp. When Porter or Brown have a cam custom ground for you, where do you think they get it? A place that has a lot of lobe profiles with which they're comfortable. Like Comp. Or Crane. Maybe Bullet or a few others. But Comp will grind you a custom cam for only a few dollars more than a shelf grind.
As to quality, the cam core determines the quality and none of the cam companies manufacture their own cores, as far as I know. So to slam a particular company because you had a ""bad lobe' is ignorant. Now if the lobes weren't the right ones, or were inaccurate, or some other deficit of the grinding process, then yes.

I don't know what you ordered for a cam but I was just giving a heads up to anyone still interested in this thread even after you dragged it down to your level ...
Just for the information of the board shelf stock at Comp is not even ground by Comp anymore, I'm told it's done by an outside firm, Engine Machine ... something like that ..., so the quality is not anywhere as good as what Comp used to be it would appear ... unfortunately.
Comp did warranty the cam and lifters and I had Dwayne Porter do a custom grind and had it nitrided, like should have been done in the first place but the person the engine was being built for wanted to save some bucks, we used the Crower cam saver lifters and all is fine this time around.

Yes Dwayne Porter told me comp will grind the specs he gives them. I believe he deals with one guy at comp who I assume is a good friend. Also my EDM solids came in a Comp box and the cam card is from Comp with my name as the grind #. But Dwayne does give them the specs he wants done. And the price was very good. Ron
