Technical What are these

Picked these up a local swap meet. They are obviously made for early SBC. They have names like "Engle", "Mc Gork" and "Sig Erson".
I know these were big names in the cam industry, but what were these used for...

 

looks like a "rev kit". there were springs installed above the lifters, then this piece sat on top of the springs. Before folks figured out how valvetrains worked, it was a crutch to get some more rpm out of an engine, without installing the valve springs that were really needed.

 

In situations like these, I have to ask: "why did you buy them?"

I am surprised at how often people here buy things then ask what they are.

 

Sorta what squirrel said.
They actually, more kept the lifter from bouncing off the cam when large rocker clearances were used in years ago. Most cams today use a tighter rocker clearance and the there's not so much bouncing around of the parts at higher rpm's.
And yes, with a more stable action of all of the moving valve train parts, not only was/is a slightly higher rpm possible, but the parts lasted longer too.

Golly, I guess I am stupid to buy early speed equipment to add to my other early garage art speed equipment. I'm going to need therapy.

 

He didn't say you're stupid. He just asked why you bought them. Looks to me like you bought them because they're old speed equipment, and you love old speed equipment. That's not stupid.

 

I have some and they're just wallhangers

 

Well you're right, I was just being sarcastic. I have a lot of early speed equipment and I recognized the names as being important manufacturers of that era. I just did not know exactly their function.
Thanks to those that responded, I can describe what they were used for to those who ask. Love this site.

 

I figured as much. But some times folks take things the wrong way...we're all here to have fun

 

Thankyou. And yes, I only asked why.

This is a civil answer. And it is all the answer I need. Enjoy.

 

Group hug...

 

If you paid $20 -30, and you want to sell it, try racing junk. com. You might make a buck, or just hang it on your wall next to the old valve covers. Isky makes a rev kit, still in use today.

Good one, sir.

curious, how do these get installed?
Looks like a tall spring goes on top of lifter with push rods running through the holes,
but what holds them in place?
the bottom of the intake manifold?

 

They go underneath the heads...there were springs that went from this plate to the lifter...it's basically pushed up against the bottom of the head in the lifter valley area.

 

Bottom of the cylinder head. I ran a rev kit in my sprint car for years.

 

Thank you! Never knew these things existed. Add some wood pegs and you have some coat and hat racks. Bob

 

To me, they are things that make me wish I'd been there at that moment when someone thought, "Ah-hah, I wonder what would happen if I made a plate and added springs to tighten up the valve train?". Some people's thought processes are amazing.

 

Or you could mount them flat (there's enough meat on the "L bracket" end to drill and tap) and use them as really cool screwdriver/tool holders

Well, we could always give juice boxes and oranges slices to everyone, so they ALL feel special...
(I've had to teach with a few educators who believed whole-heartedly in this philosophy over the years... all I could do to not crown them with a 2x4 )

 

Coincedentally, I identified this same part for a vendor at the fall swap meet at Stafford Springs who didn't know what it was.
