1967 Hemi lifter identification

[eric383]

Can anyone tell me what kind of lifter this is? I was always under the impression that a solid lifter was solid but these lifters I removed from my 67 Hemi don’t act like hydraulic flat lifters. Meaning if you take a screwdriver you can’t compress the lifter. I know the 67 Hemis came from the factory with mechanical lifters but who knows what has been done since 1967.

I no hemi expert but that sure looks like a hydraulic lifter to me. As you've stated, solid lifters are solid, no plunger, or retaining clip. 440'

Not really sure that is true....I believe I have seen solid lifters that had internal pieces and filled with oil to make them solids.....I am sure someone out there has more knowledge than I do tho...waiting for someone smarter than I to chime in...

E, ask Thunderlugs....if you need his # e mail me....or message him here

so now you started playing with that beautiful machine ?...lol
can't wait to see it

Yup I've been heading down the rabbit hole for a while just trying to correct things. It's always a mystery when you're digging into the unknown.

Sure looks like a hyd lifter to me.

Keep in mind I’m looking at a pic on my phone....... but it looks like a 67 and earlier style hyd lifter. Those have a smaller diameter pushrod seat........ which is what that looks like to me.

Then the question becomes...... what’s actually in it for a cam?

I don’t believe Hemis ever came with pushrods that would correctly fit that lifter.
How about a pic of the bottom end of the pushrod?

It looks "hydraulic" to me too. I have seen "solid" lifters with removable seats and clips, but had a ledge inside the body to restrict movement.

The cam is unknown since it came with the running engine. As stated in my original post these don’t act like hydraulic lifters because you can’t depress the plunger with a screwdriver or the pushrod. I’ll have to get a pic of the pushrod end but it fits perfectly in the cup with no slop.

Just because you cannot depress them with a screwdriver doesnt mean they are not hydraulic, just means the springs are too stiff to yield. It looks like a hydraulic to me but I am thinking they might be some after market lifter marketed to act like a solid but have enough movement to also act similar to a hydraulic in that they do not have to be adjusted as often.

Might be older Rhodes type lifter,acts like
hydraulic,but at around 2500 Rpm becomes solid.
Also sounds like solid at idle ,because of calibrated bleed down .

You can verify what they are easy enough.

Thoroughly clean all the pieces of the lifter with solvent and blow dry.
Reassemble dry.
Try working the plunger up and down with something like a Phillips screwdriver.
If it’s a hyd, there will be a fair amount of plunger travel.
Then, place the lifter in a container with enough oil in it to submerge the lifter.

Pump the plunger with the screwdriver....... and the lifter should pump up rock hard.

That would be a hyd lifter.

If it’s solid, after you reassemble everything dry, there will be basically zero plunger travel.

Any solid lifter I have taken apart has no springs or plunger.
There is a pushrod seat that sits on a step in body, with a snap ring to hold it in place.

Other types of solid lifters are just “solid”(one piece), and some have a pushrod seat that’s pressed in(no snap ring).

The 67 and earlier hyd lifters use a pushrod that is necked down to about a 1/4” in diameter at the very bottom.

However, I don’t know if the earlier solid lifters used that same style of pushrod or not.

The spring says it's a hydraulic. There are multi-piece solids, keeps the weight down, but there always is some solid path through them. No need for a spring.

My pushrods are not necked down like those. I was wondering if they were something like Rhoads lifters because the clip that holds the plunger in place looks different than the hydraulic lifters I’ve dealt with in the past. It’s always interesting try to unravel what has been done in the past.

Let’s see I pic of the clip

The pushrods are 3/8. Here is the lifter disassembled.

Definitely a hydraulic lifter..

That’s a hyd lifter.
The only company I’ve seen use that style of retaining clip is Hylift Johnson on the “R” series lifter.
The purpose of that style retainer is to push the plunger lower in the body, which reduces the volume of oil within the lifter.
They’re designed to be run at “just zero” preload.

The high/thin oil band would be the “976” lifter.
With that style retainer it’s a 976R.
The pushrod seat should not have a through hole in it.

A less molested clip from one of those:

Thanks for answering the mystery.
