Kinda off topic but there are Hy-lift Johnson and Johnson lifters. They both claim US made. Who knows the truth? Looking for a set of hydraulic rollers for a Gen III Hemi. Just want quality.

Just a comment having spent a reasonable mount of time in corporate R&D as well as manufacturing.
Most major manufacturer's have Final test procedures of some type. There are normally also different specifications supplied by the end user (say comp cams)
During the manufacturing two identical parts made at the same time on the same machine may perform differently for a number of reasons to numerous to list. So we have Final Test. This is where the completed parts are subjected to a variety of tests under different conditions and then sorted according to their performance. For example:
A "Bin1" part is the highest quality and consequently is priced at a premium.
"Bin 2" is slightly lower on performance and priced cheaper.
"Bin 3" is middle of the road on performance and priced cheaper yet.
"Bin 4" is still functional but may fail if exposed to Bin 1 spec's
'Bin 5" is a reject and gets recycled of scrapped

In addition, The end user say Ford, may require their own set of test parameters: In the case of hydraulic lifters it might be x amount of spring pressure with different viscosity's of oil under extremely hot and cold temps.

Blueprint engines may be buying Bin1's

Comp Cams may be buying a bin 1, 2 or 3 part.

the local parts house will likely be selling bin 4's as their house brand, TRW may be Bin 3's, Bin 2's and the

Joe Blows engine kit supply company is going to go for the bin 4's and probably other stock crate engine rebuilders.

One also has to keep in mind the current supply chain problems may have caused some deviation in acceptable quality as well

In closing I will also say we have 3 rethreading kits. 1 Snap on 185.00?, 1 Mac tools 125.00, and 1 Craftsman 59.00.
They are ABSOLUTELY identical in every way except for the label on the outside. Even the inside label is the same as is the box and its grain patter. Are these Bin 1, 2, 3 tools or are they exactly the same? only the Manufacturer and the buyer at the 3 companies know for sure

'Johnson Lifters' is good quality performance lifters, they make pushrod oiling Gen III roller lifters and also do lifters for GM for the Copo Camaro race car. Have had issues with 'Hylift Johnson' lifters from Comp on several engines - Mopar and others.

FWIW, this is a quote from Mike Jones (Jones Racing Cams) on another forum where people were asking about what quality lifters were available for SBC these days: "We've sold thousands of the Johnson-Hylift lifters, since they changed to the new foundry, and have had zero issues."

Considering the state of the industry (outsider's perspective), I'd want to be sure of where my lifters are sourced these days.

If you get a chance, take one of those Bullet lifters apart and get a pic of the internals.
