Hi Larry! I still get confused on this . The “Shaver style” are the older ones, right? I took a pic of the lifters I have on hand.

They are the Speed Pro that’s used with the plate system, then what I think is the Shaver style and on the right the newer Comp lifters. Am I all screwed up on this?

If this is correct it would seem to me that the Shaver style would be the most likely to have trouble with a reduced base circle.

Anyone is welcome to help me out with this.

Thanks
Murf

Hey Murf,
I have pics of them side by side, maybe you can compare them to yours and figure this out. These are both from Comp for a Pontiac. The pair on the left are Johnson that Comp used to sell, now sometimes I think they substitute Morels. The pair on the right are the "S" lifter that Tom commonly refers to them. They are Shaver lifters.
As you can see the "S" lifters actually have the correct oil band and are slightly taller overall.
The problem I ran into was that they both (at the time) carried the same part number for a Pontiac from Comp Cam. So I would order these but you never knew what was coming in the box until you opened it. It just depends on what Comp has in stock at the time. I think that's where the problems start for people that buy these things and don't realize there are 2 different bodies floating around. Then the confusion begins.

I got to the point I wanted to make sure I was getting the "S" lifters. I bought the last set from Paul K. on the forum. Great thing about that is that Paul is nice enough to open the box, make sure they are the correct style, and then ship them to me. When in doubt, order from Paul K. They have worked and run whisper quiet for me in the Pontiacs. Tom has mentioned they are made in Southern Cal.

Thanks Larry do the ones on the right in your pic only have the upper part where the link bar is like the ones on the top in my pic? They look about the same to me.

That single SpeedPro in my pic seems to have the band higher than the older Comps and closer in height to the one on top in my pic.

Part of what is screwing me up is that people are talking a lot about base circle on the Speed Pros but I don’t remember much talk about it with the older lifters with the lower band. How’s that for a run on sentence? 😀

I believe it is the same as your pic Murf. I have a couple pics of them I'll have to fish for and see if I have a back side shot.

LOL I understand what you are saying. I don't recall any discussion about base circles years ago with the older lifters. Oddly enough the short set on the left of my picture about 15 years ago were run in a 455 with a 254/262 @ .050 hydraulic roller that was around .600 lift and those things were perfectly quiet.

I`m running the Johnsons on the left. 400 lobe cam. 3/4 turn preload on 7/16 studs. No problems. Quiet. Have been to 6500 twice and 6000 many times.

Nice to hear of another example, I just got done posting that those very lifters were in a 455 we ran years ago on a 254/262 @ .050 cam that was pretty rowdy and they were quiet. Dad would shift that one at 6000 quite often, had a 6300 pill in the box.

I think the Johnsons just have better internal parts and less bleed down hence they don't have problems with noise even though the oil band is a bit low.
