Comp Cams 821-16 Solid Lifter Review?

[gzig5]

I fell into a good deal on a set of new 821-16 lifters and I'm not seeing much review info on them. I was a little surprised there is no reduced band on the body like many lifters have. They are cylindrical. Anything to watch out for in using this lifter?

I've been leaning toward a SFT cam for the upcoming improvements and now I can't use lack of parts for an excuse. Should give a higher top end for the 340 and maybe 20hp over a hydraulic cam that gave similar lift and timing at the valve? I know you can't compare solid and hydraulic cam specs straight up.

I had a set of those. Look very close around the edges. The lifters I had had a bunch of chips around the edges. I sent them back and ordered some from Jim at Racer Brown.

As to the lifters themselves, if they don't have physical issues, they are a quality lifter. I never run the lifters with the band around them, because I never run pushrod oiling.

I prefer the the lifter body without the oil band.

Like I said, as long as they don't have some physical issue, run them.

I have one on my desk....they are made by Johnson Lifter and are a quality piece.

I bought one to inspect before I bought a set.

Thanks. That gives me piece of mind. Considering I paid $22 delivered for the brand new box of sixteen, I'm pretty happy. The savings is going towards a custom grind when the time comes.

That cheap!
They have a snap ring, hole in the push rod cup ..if I'm not mistaken they fill up with oil through that hole, splash/runs down push rod. Someone said the cup is lower than others... I still have to measure, for I bought a single 821 to replace one that has a nic...but the rest that are solid body, so I'm re thinking that if its a deeper cup as well...I'd have bought a whole new set if I could find it cheap.
I digress.
Right on.

In the 2004-2006 time frame...... what I refer to as the “lifter debacle” era....... things were not good for .904 sized flat tappets ........ if you wanted something made in the USA.
Hylift-Johnson had closed, Eaton decided they didn’t want to be in the flat tappet business anymore, and Delphi didn’t make .904 flat tappets.

That left Stanadyne.
Not really anyone’s favorite HP lifters.

The Stanadyne Mopar solid lifter was truly “solid”....... as in one piece.
No powdered metal pushrod seat to crack and fail, or snap ring.
One solid piece.
The big drawback, aside from what was often inconsistent sizing, nicks from being banged around, complaints of the crown not being centered...... was the fact that “solid” also meant “heavy”.

During that time period, Comp sold those Stanadyne solids as 821-16’s.
The choices for non-exotic Mopar solid lifters at that point in time were the Stanadynes......or something imported.

So....... what you have for 821-16’s can depend on when they were packaged.

A few years later after Topline bought Hylift and opened the doors back up, the 821’s could be either Stanadyne or Hylift.
I believe that remained the case until Stanadyne stopped manufacturing lifters.

Nowadays, they’re Hylift.

If you have the Stanadyne version, be sure to mic the OD and make sure none are bigger than spec.
I’ve seen them as big as .9045”.

I always liked the old MP solids that were .0005” undersize, @.9030”.

These came from Amazon so I wouldn't think they would be extremely old. The manufacturing label on the end of the box has a 05/15/19 date on it. They do have the snap ring and separate seat with a hole in it. I was wondering why they would do that. The bodies look like they could be powdered metal which again is surprising. I would have thought it cheaper to lop them out of bar stock, lathe bore them, heat treat, and then center-less grind the diameter and do the end however that is done. But what do I know?
I'll check them out and compare to the hydraulic ones that are in another Comp cam kit I got.
