Summit has the Howard’s in stock. The issue is you will need to make sure the lifter doesn’t drop too low on the base circle and close off the feed to the oil band. It’s a super easy fix that will not affect the future changes if you swap to something else later. Just use a chamfer bit or larger drill bit to chamfer the hole just a touch. (Will need the block disassembled to clean afterwards)

Thanks again,

Wow on the Howards mark up! I paid $200 for my Gaterman lifters with the original boxes 😎

[ponchjoe]

I haven’t heard anyone talk about the Hylift Johnson version and those are the only HFT lifters I’d ever run.
Any thoughts?

P@blo,

I am guessing you bought them pre covid? I’m gonna have to reevaluate my price the next round and if it’s even still worth it. The main demand has been filled. 42 sets plus a couple for me. I made $15 per set for my time, gas, and packaging. Probably made enough to make my sets free. I did it for my build and a few folks talked me into making a few more sets for them. That’s what started this. The last sets I had made the price went up $1.20 a piece. (Cost of material is going up) That’s $9.60 more a set. I don’t think many people are gonna pay more than what I have been selling them for.

I have been fronting the money buying 100 pcs at a time to keep the costs down. I have several sets left right now and can’t continue to have thousands of dollars tied up for long periods of time especially when I’m barely breaking even.

Sorry for the long post. It was definitely fulfilling contributing to the Pontiac community!

Thanks,
Stuart “Stan” Landreth

What you are doing is a good thing Stan. Not ever going to discount that so hopefully I did not come across that way.

Lifters were bought in September 2024. They have the vendor sticker over the Gaterman.

Also, the pin oiling is only on one side with the Gaterman. Not sure what Howards is sourcing now but I am betting the supply demand issue had them knocking on other factory doors for stock. Especially with a 100% mark-up.

I am looking at the HT-2148 and not the HT2148A

[ponchjoe]

Anyone have a set of HT2148s they’d sell? I can’t find any

[Stan65]

Dragncar,

$200 for just the retainers if you want to use the ford spider, or source your own bolts, springs etc.

If you want the hardware that eliminates the need for the spider, add $50.

Those prices are shipped in the 48 states.

I sent a PM

Thanks,

What is the max lift you can use with this setup? If I can run my 581 lift camshaft I might use this as an option. I don't really care for the retrofit lifter

[Stan65]

I sold out including one spare set that I held back for myself last week. I talked to the machine shop I have been working with about current pricing on the bar stock with all the tariff stuff going on. Well they have enough on hand left over from the last couple runs (they buy in 24’ lengths) to make 7 more sets at my current pricing. So will have more coming soon.

Thanks all that have supported this adventure.

I will definitely be keeping my spare this time. lol.

Stan, Any plans on making more of these? Just starting my project. Also what's the cost on these?

Thanks, TJ

Advance Auto Parts has them in stock around here.

[Stan65]

Scream n fly,

I would say that’s pushing the limits. It would require accurate measurements.

Can you measure the base circle on the cam?

Stan

Down to 3 sets.

[gtobob67]

That is so true. I bought an Sealed Power HT-2148 recently at Advance to make it solid so I could measure pushrod length. Guy behind the counter brought out the HT-2148A. He then went back and brought out the correct part. Be careful....

I checked Advance this morning and they only had 1 they could ship

67Lemons,

Lifters explained…..

The first step in determining if my dog bones will work for you. It is all dependent on the base circle and lift.

Max lift is when the lifter is on the tallest part of the lobe. The lobe can’t be taller than the bearing journals or the cam could not be inserted through the cam bearings. “Most” cam manufacturers have the lobe as tall as possible to help with the angle of the lobe to the lifter base. Usually just a touch under, like .010” smaller than the cam bearing journal diameter.

The way lift is increased is by reducing the base circle. (Lift is the difference between the base circle and top of lobe)

The issues with running a non link bar lifter is none are made specifically for a Pontiac. Through the years several people have experimented with different OEM lifters.

Lifters proven to work…

I used Sealed Power HT-2148 lifters when I designed the dog bone retainers as I didn’t like the way the ford retainers fit. (This is the lifter folks were using with the Ford spider and Ford dog bones)

In the dimensional drawing below you can see my setup. If you reduce your base circle compared to my base circle, the lifter will drop lower by half the diameter difference and you should be able to subtract that from the amount the oil band is above the bottom of the bore to determine how comfortable you are.

In the picture of the two lifters with the red circled area, the one with the red circle is the HT-2148 lifter. The one on the right in the same picture is what people call the LS7 lifter. The notch for the oil feed hole on the LS7 lifter is higher on the lifter and will raise above the bore at lift and leak oil therefore it cannot be used.

The picture of two lifters without the red circle are on the left, the Howard’s/Gaterman lifter. The Sealed Power HT–2148 is on the right. The issue with the Howard’s/Gaterman lifter is with the oil feed hole lower compared to the Sealed Power lifter. There will need to be modifications to the block with the Howard’s/Gaterman lifter. When this lifter is on the base circle, the oil band/oil feed hole drops completely below the oil feed galley in the block. It’s not by much and will only require chamfering the oil feed hole the slightest amount to maintain oil feed on the base circle. The only issue is the block must be fully disassembled so that you can clean after the modification. It doesn’t require any special tools just a drill and a chamfer bit or even just a half inch drill bit to just to put a chamfer on the opening of the hole.



My retainers will not allow you more lift, less lift or the ability to use any special lifter. They are just designed to keep whatever lifter works in your situation from rotating.

I can’t answer to the quality differences between the USA, Mexico, and China seal powered lifters.

Hopefully this answers some questions.

Thanks,
Stuart “Stan”Landreth

By the way down to three sets

[Stan65]

All,

Just finished what is likely the last run of the bones. The cost of the material and machine shop time going forward will just be too expensive and I believe will put the cost beyond what most will spend.

This is the last 12 sets which makes 96 sets!

Thanks,
Stuart “Stan” Landreth
