I was around the LS circles for more than a decade and had 4 LS powered cars over the years, with cam swaps in engines well over 100k miles. Not only did they work flawless for me, I never once heard of this issue from any other LS owner........ever.

That fair. BUT, good retro fit roller lifters are EXPENSIVE. If this more factory style setup can be had at a much lower price point, I think it’s still a worthwhile addition to the shelves. Especially for the mild street guy who wants to upgrade, but balks at the cost.

Or hell even cost aside, how many times have we seen that the Johnson roller lifters are out of stock? Like I said I’m all for more options.

I would like to know where the lift line is for this setup though. I know the gen 6 BBC guys stock using the stock setup at a certain point.

I think this is a viable option. The sealed power lifter is a very good quality lifter. I have run a similar setup using the 2148 lifter and it works well. The limitation I have had is depending on your block and how the lifter bore holes were finished (some have a chamfer from the tooling) the lifter oil hole will come out of the life bore at max lift and this happened somewhere between .385 and .400 lobe lift. This is very block dependent so you need to check closely on your block with your cam. I have experimented with the ls7 lifter and the oil hole is way to high in the lifter i will attach a picture once I get it off my phone. Im glad Randy Is woking on this project as it will be cost effective. The main advantage to this over a link bar lifter is weight. This set up is much lighter than a link bar lifter allowing you to run different valve train components that help extend life and increase higher RPM potential. Just my 2 cents worth.

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.

i thought the point of owning a pontiac was so that you could throw buckets of money at half-ass engineered chinese-made aftermarket junk until you got so sick of the noises and your engine running like crap that you sold it all on craigslist. then you finally come to your senses after a few divorces and wind up with a factory iron intake, quadrajet with working choke, exhaust manifolds, and a mild cam. once you are done your car is so mild you never drive it because your third wife always drives it instead of the subaru you bought her.

so you’re not really a pontiac guy until your third wife is cruising around in your gto or firebird while you are driving her subaru and working two jobs to pay the alimony and child support to the first two wives.

you figure out an easy and reliable way to convert a pontiac engine to a factory style hydraulic roller setup, and you will put an end to our way of life!

I believe they are off the shelf LS7 lifters

I had some LS style HR lifters to try on a Stump Puller and the oil band looked way off like it might hang on the lifter bore like a SBC lifter can.

Will the finished product be shown soon?

My work truck has 355,000 miles showing on the clock and has never had a valve cover off. Sure its on the second tranny and the second rear end but all engine internals are original including buckets. Idles perfect and does not smoke.

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?

This is not "new" to me. I ran a modified set of solid roller lifters with a plate system for years in a 4 speed, 4.88 geared GTO before any of this fancy hyd roller stuff was available (1981).

After waiting on Johnson to make another run of hyd rollers for our Pontiacs and having delay after delay, I decided to make my plate system available before hearing about the spider which has too many loose parts that need to be modified and lead to failure.

I'm making a single plate system that's adjustable and will be standard equipment on our Injun builds. It's solid and won't be the cause of a failure.

Jim's idea may work great but as for me, no Ford parts will be found in our Pontiac builds.

The AIRLPGS will work with any heads but the cast iron heads are on the back burner.

Hi Matt,
I'm careful not to "claim" anything I can't prove. 24 sets in stock. See attached pics. Lifter prices have been reduced starting at $199. https://pontiacspeedshop.com/valvetr...oller-lifters/

Hi Paul,

All our cylinder head projects are on hold.

Because of the current business climate?

I’m impressed! Now let’s see these in action!

Thanks for your efforts toward improving the Pontiac aftermarket Randy!

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

sorry havent been following this thread, are these sealed power lifters ready to drop in & run or do they need a plate or link bar of some type?

& whats the difference between the 199.99 & 239.99 lifters?

They require the Arrow Injuneering Roller Lifter Guide Plate System https://pontiacspeedshop.com/arrow-i...-plate-system/

The difference in the two lifters is the way the plunger is retained. The $199 lifter set has the standard wire clip retainer and the $239 lifter sets have the positive snap ring retainers.
