well here it is.

Rhodes Mopar RL2018 vs my lifters with the suggested snap ring from @Diplomat360




i think it should be ok a million times better then the clip.
and every lifter i see for the 440, their snap ring looks exactly the same.

i am still working on getting a package of crower's snap rings to see if they fit.

three more weeks for the new rockers and push-rods.
wish me luck ill try to update my results.

I had a set of Crower hyd rollers with the same retainers as those. They wouldn't stay in the lifter, I found 2 or three that had come out. The problem with them was that the grove that they were in wasn't square, but just a round grove. I threw them out and got something better.

Sorry, I have not been able to find any of my old photos and the lifters I did actually re-built (the older style original ones) are somewhere in my Mopar parts room, which is an un-excusable mess.

OK, the photo you posted does look exactly like what my install ended up being. Makese sense, I think we both used the same parts. Given that the internal plunger was only barely retained with the ring eye-lets I just didn't have the guts to run 'em like that. So I went ahead and ordered a new set of lifters which no longer have that same design.

I agree, I think even with these rings they provide a much harder plunger stop...but I would be worried about the lifter pumping up and if the groves in lifter are not perfectly square it would take very little to possibly pop that ring out completely.

I put the flat side up and radius side down so it fits nicer in the groove. Either way. I'm now scared of the wire retainer costing me another set of custom magnum pushrods since they take 3 weeks to get in.

Since they look like all the other snap ring hydraulic lifters. I'll take the chance. Its still far superior then the wire retainers.

I will update with results. If these fail then I ll be forced to get diff lifters and or go mechanical with adjustable rockers.

I used a set of the same lifters from Comp in my recent 340 stroker build, three or four of the retainers had come out or where coming out after less than three minute run time
I blame that on trying to use 3/8 pushrods with Edlebrock heads and Harland sharp rockers, maybe that is not so

well i hope not i just bought a set of magnum 3/8 9.300 push rods.
however the ends are still 5/16ths

@Cab_Burge did you mean the Rhodes Mopar RL2018 or SealedPower HT2011R?

i know 440s and most of the mopars dont like high oil pressure when using hydrualic lifters.

i have mine locked at 60psi. no higher no lower unless theres a failure of course.

The Seal Power type looking lifters from Comp Cams
I would never use a Rhoads type lifter in any of my or customers motors

comp cams Hi-Tech™ 882-16 Hydraulic Lifters: AMC V8; Chrysler V8


Sealed Power Hi-Rev Hydraulic Lifters HT-2011R


i think im going to proceed and replace them all with the snap ring.

I would never use a Rhoads type lifter in any of my or customers motors tsk twocents


Can you articulate as to why?

so far seems to work fine.

sadly though cant high rpm test.
possibly spun a bearing on the same cylinder the rod went on.

shes out for the season. time for a high volume pump and bearings.
hopefully crank/rods ok. will know once pan is off.

FYI the magnum pushrods are sexy as all hell

Holy smokes...that just seems crazy...the Comp Cams lifters (judging by the photo you posted) end up looking precisely like the fixed old-style SealedPower lifters...so maybe that little interference between the snap-ring and the inner plunger is actually sufficient enough???

Either way, sorry to hear you ran into another problem having overcome this one.

I don't like using parts that patch up a problem that can be fixed properly with the correct part selection
That and there history of making noise and less power at idle

i dont think the tappet is the cause of the pump-up failure.
its the actual piston/plunger. the outer piece.

i still havent opened the pan yet. this month has been too stressful.
i dont want to be haunted just yet. will keep you guys up to date.

did a couple pulls the snap rings seem to be doing their job.
will put a few miles on them and see

Ok so for my hyd lifters (not sure what brand) I need the HO-68 snap rings?

Yeah they work.
Just a tip though put the curve side up.
Flat side towards the tappet.

I did a few 6k pulls through all gears no issue so far.
Will open rockers in a few weeks when I park her for season.
Plates registration ends Oct.

thank you. I emailed em for a quote/shipped. I would think you would want the flat side up to be more secure against the cup/snap ring flying upward but I will go with your recommendation.

the cutout inside the lifer is round. having it rounded side up fits more snug.
if you do it the other way there is a gap



stupid hot outside, did a few HARD pulls to 6k
still together.

Noted (& wrote down). thank you!
