Get your factory lifters re-faced. Or any lifter made prior to 1995. You will then have reliable lifters. We have doing this here for DECADES.

We have no issues with our US made flat tappet lifters, and have them in stock.
They're made by Hylift Johnson, and are the only major lifter manufacturer, who's flat tappet lifters are 100% USA manufactured.
The bodies are produced at a foundry in Cleveland, and they are finish machined in Michigan.
This is the same lifter we've been selling for decades, and we sell thousands of them a year.
The price has almost doubled in the last few years, but they're a quality lifter.
We only offer the mechanical flat tappet lifters with an EDM'd oiling hole in the face of the lifter. In circle track applications, we found the oiling hole increases the life of the lifters and cam by about 300%.

thanks, Mike I found a set of the Cam savers from GM Delphi I had a small slot cut in them. I really wished I had just used hydraulic roller lifters. It was a Big block corvette Mild 496.

The EDM hole lifters are the only way to go with solids!

I bought the groove tool and used it on a friend's engine when i put it together ,, engine lost a rod bolt after 2 years of 8000 rpm in a dirt tracker ,, this was approx 6 years ago ,, the cam and lifters looked new except the cam broke in 2 pieces from contact from the bad rod
The groove tool and lifter bore hone till it just spun easily ,, proper break in ,, he wanted to shut it down after it had a slight problem ,, 10 min in ,, nope ,, no can do
I've been away from this stuff a while but it sounds bad out there ,, ,,
Good to know Cam King ,, I've got 2-3 new cams here but was afraid to put em in something

Mike, since we're here & talking about lifters:
My go to hyd roller lifter is a memory (crane), how do the hylift Johnson lifters compare?
They're significantly cheaper than the crane were, but more than the crappy morels everyone over here sells.
The morels fall flat on their face at 5800-6200rpm, the crane used to spin out to 7 no problem

I’ve used the cheaper morels for years and haven’t had that problem. The price of the morels has risen significantly recently so I’m looking at the Gaterman lifters. Heard good things about them . Pricing is decent as well.

just looking at lifters. 2 things have to be prevalent 1: Convex curvature on lifter face and 2: hardness. You have to have both.
Now if u want to include the cam, then u have to have taper. The lifter has to be offset to the lobe and it must spin on the camshaft. If it no spin, then it no last. ---Flip lifter upside down and us dial indicator to measure curvature. If you cant do this, put to lifter together on their face and you better be able to see daylight all around the edges. Hardness is a hard one to determine if you dont have a ahrdness gage but can be approximated. Saame on camshaft on hardness but taper can be checked in between centers

Put them on an aggressive .400" Lobe with 160lb+ seat pressure & they bleed down at higher rpm, power nose dives & motor staggers coming back to idle for a second or 2 as they pump back up.
Used in milder stuff they're fine - but what's the point of a roller if I can beat it's performance with a solid flat tappet at 1/3 the price?

I have not used the Hylift Johnson hydr roller lifters on any aggressive cams.
They work great with .375" lobe lift and a PAC 1218X spring

Yes, that's all I sell.
The Foundry they used went bankrupt during the Covid shutdown, so they had to contract with a foundry in Cleveland. That put them way behind.
The first run of Chevy mechanical lifters shipped around the beginning of the year. Shortly after, the Chevy hydraulic lifters shipped.
We've sold over 1,000 of them this year, and have had no issues.
