Default New Hydraulic Roller Lifter option - Arrow Injuneering / Sealed Power

Interesting new hydraulic roller lifter option for traditional Pontiac V8. Claims “Made in USA”, and under $300 (listed at $295) for set of 16.

Ad says you need their Hydraullic roller retaining system. But I couldnt find that on their website. Wonder how much that is or how it works.

Looks like they have been machined for something like a dogbone?LS lifters?Tom

I saw it on facebook. They said availability of the retaining system is early 2021, and that the package should be cheaper than other retrofit roller lifter setups.

Im curious if the lifters are purpose made or if they are off the shelf SBF or something.

I like it. Ive never been happy with the noise of my comps.

Anti-rotation system comments from Arrow Injuneering:
“We are putting a system we have used since the '80s into production. It's so simple and easy to install that once you see it you won't believe the "Injunuity" of Arrow Injuneering! Coming Early 2021!”

It will be a really nice upgrade if they can come up with a retention/guide system that's pretty much a "drop-in" and allow the use of those style lifters in lieu of the type that require a link-bar.....IMHO.....

JMHO,I started running roller lifters about 1964 and linkbars have never been a issue for me!Tom

I don't mind the retrofit stuff and have never had a problem with what's offered on the market with our Pontiacs, or any other brand engine.

Interesting that people are trying to come up with new ideas, especially for a Pontiac, but I really don't have a need to try it at this point.

I like the idea of these lifters but it seems kinda silly to have them advertised for sale with no way of keeping them from rotating yet.

In theory they shouldn't rotate as they are two flat surfaces one turning the other, but we all know that it's not a perfect World and you'd better wait for the associated parts to keep them lined up correctly!......LOL...

If plans work out I intend to move to a HR cam and may well give these a shot, pending the anti-rotation system.

I wonder if they got Sealed Power to make these with pontiac specific oil band location, or if they are just the standard sbc ht2148. The picture looks like the sbc lifter, but hard to tell. When I measured up an ht2148 a few years ago it looked like there would be a certain lobe lift you can't exceed or the band will come out the bottom of the lifter bore.

I've always wondered why non-round shaped lifters or lifters with a keyway that would fit in a groove aren't made, with the lifter bore machined to accept a non-round lifter that wouldn't be able to rotate.

Guys!Again,most of the issue with roller lifters have been with virtually ALL makes of hyd roller lifters.Only solid lifter issues for the most part have been in lack of maintenance and most in street applications!The link bars are NOT a real issue.Tom

Food for thought. These look similar in design to GM LS lifters that use the plastic bucket retainers. Those are removed in favor of tie bar lifters due to rotation even with the buckets. This occurs with aggressive cam profiles along with typical engine heat softening the plastic. Seen it first hand. Only takes a few seconds to warrant a new cam. If the retainer for these is plastic, I would shy away.

I am finding very hard to believe GM would make these for 20+ years and this "issue" would happen and it would not be well known:

Do you have any evidence?

My other car has a warmed up 6.0 LS in it. 95% of the guys in the LS world are still using the stock lifter buckets with streetable cams. In the LS world that's any cam with under .620 lift and some running up to 240's/250's duration. There are certainly guys running linkbar setups, but most are pushing wild lift/duration cams and spinning well beyond 7,000rpm. If this setup ends up working as well as the GM LS design I'd gladly throw a set in my car with a mid-high .500 lift cam turning less than 6000rpm without any concern.
