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.

This is an ls7 lifter on a cam with .377 lobe lift. You can also see the factory chamfer on this lifter hole. This block has 2 holes chamfered like this.

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!”

Aren't they the guys that were bring several new cylinder head options to market?

Hi Paul,

All our cylinder head projects are on hold.

Because of the current business climate?

Still need more time and money in R&D and right now both are invested elsewhere in the Pontiac hobby. Thanks

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.....

[tom s]

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

[Formulajones]

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.

Will the finished product be shown soon?

Yes. Very soon!

You get the impression the pigs are getting fed? Jim Leheart shared an idea, no profit involved, then along comes the marketing department but no one has even tried the dog bone kits.

The question remains, can this new system be converted to the cast iron d-port cylinder heads you were going to offer?

One area you don't hear about with the drop in Hyd Roller Lifters is the lifter body going below the oil feed hole in the lifter bore. The measurement is 2.000 from the base circle of the roller cam to the top of the oil feed hole in the lifter bore. This measurement is based on a 1.080 base circle cam.
Using our big .400 lobe lift cams, the Gaterman 1012 lifters still have a little room to spare as pictured in the first two pictures. The Sealed Power HT2148 lifters will expose the oil hole and spurt oil when the cam is on the base circle.
Our .377 lobe lift cams have a 1.135 base circle and work fine with either lifter.
Test your setup prior to firing it up by installing the cam and just placing the lifters in the bores. Keep the valley pan off and use your oil priming tool to prelube the engine and you'll see if it's losing oil. Some oil seepage around the lifter body is to be expected but if it looks like the Clampet's striking oil on the Beverly Hillbillies, you're asking for a rod or main bearing failure.
The key is to use a Hyd Roller cam with a 1.135 base circle or larger on a HT2148 lifter. Let me be clear, it will run regardless but at continued high RPM it will pump the oil to the top and bearings are going to suffer.
For anyone who has built an engine with these lifters and a large hyd roller cam, IF you don't know your cams base circle dimension, call your cam manufacturer and find out.
The hobby can't afford any more Pontiac blocks being destroyed.
