WEll, sure as shyt I lost a lifter at a track rental Friday. I found it yesterday at Gainesville when I heard a squealing noise while Warming the engine. It's an Isky EZX bushing Lifter. No notice whatsoever as I track lash changes. I had just lashed the valves before the test session.

No idea what the damage is. BAM lifters will get a hard look. I think they are here in Florida. If so that makes them a local product and likely to be used next. Gosh, I hope I caught the damage soon enough.

You might not see him in person, but Lord, he'll see you just the same. Talking about him.

How many passes were on them?

He gonna get a set of Denny Steward needle bearing lifters.

Hot ticket

I’ve lost an EZX late in the 2019 season during our run at the S/C world championship, without warning that roughed up the cam lobe too. Put a new lifter in it, lashed it .004 tighter than spec and finished the season logging another 20 passes.

218 licks which is also what the engine has on it. my last set went 500 passes on them. I still have those here. I've pretty sure the cam lobe is trashed. I've another duplicate cam here that I can use. BTW I use PAC 1325 springs and they were all seat tested and inspected the day the valve lash was done.

If any of you guys want to step up to a Jesel lifter send me a PM.
They offer needle rollers or bushing style.

PM a quote Sir, when you have time. 904 sbc, max offset intake. Needle bearing JESEL lifters.

I had a long talk with Brad Miller at BAM yesterday. At this time he cannot supply me a .904 lefter set as he is waiting on main bodies. Nice guy. He told me of a TD that now has 2800+ runs on a set of his lifters.

I'm sure Scott Duggins aka PAR has them in stock

Vincent performance may be worth a call they are a dealer but in the environment today I wouldn't be surprised if it's hand to mouth and he is carrying a fair number of back orders. I got very lucky to not have a 3 to 4 week wait on regular .842s in Feb. They ain't cheap but they are a great design. IMO. He really is a good guy and very open and honest. Ed is right for the number of engines they do PAR is worth a call.

I'm calling straight up bullshyt!!

this $35-45,000 engine new would have had everything in the block and heads replaced at least twice with 2800+ runs during multiple rebuilds/freshenings adding thousands each time. Why would anyone leave the lifters in waiting for one of them to shyt the bed? Now if the claim is they are the original llifters that have been rebuilt multiple times then no big deal.
Marketing claim 101

Pic of some apart.
I forget the number on these....it was a bunch...my recollection and understanding was he has disassembled and reassembled multiple times......I believe the axles and wheels where reused but a phone call to him would answer it definitlevely I'm sure. Big Dollar bracket racer who puts a bunch of runs on. I think the take away is that the axles design has held up for a lot of cycles. Which essentially the biggest difference between the BAM steel (no idea on alloy) with DLC coating and the design with the bronze bushing like Isky Or Morel or others.....I am very interested in hearing how they are performing for everyone. Good or bad.

I agree the devil can be in the details. I'm sure he would be happy to put it to rest and explain what maintenence was done or components replaced.

Define Top Dragster, it ain't a centrifigul supercharger Top Dragster running at the front of the pack.

You might get an experienced guy keeping close tabs on lifters at that level, around 500 laps with lifter rebuilds, but no where near approaching 2800. This caliber would run JESEL needle bearing lifters anyway, because of the associated valve spring pressures.

I don't think high spring pressures will be an issue with these. You can talk to Brad but I think that is the main idea. Disperse the load over over greater surface area.

Stress = Force ÷ Area

You'll never see a bushing lifter in a Pro Stocker, same concept.

Don't be surprised to hear the new all aluminum PAR engine everyone is discussing, has needle bearing lifters, either.

For what you're doing, they're great. They'll dig grooves in a non tool steel camshaft though, with a lot of spring pressure.

I definitely don't need to talk to anyone though, I know I'd prefer JESEL needle bearings above all, then Crower what I've always used..

BAM, ISKY, Crower (quote from their site) and Morel will all tell you the same thing, bushing lifters were developed for longevity in high spring pressure applications.

From CROWER site:
[This premium roller series includes NBO (Needleless Bearing Option) and HIPPO (High Pressure Pin Oiling). The NBO is our high tech needleless bearing built to withstand today's severe valve spring pressures and extreme rpm ranges. The "HIPPO" feature feeds oil directly into the center of the roller bearing assembly.]
