The FTC enforces “Made in the USA” claims under its deceptive advertising laws. They apply to products sold anywhere in the United States. The rule is that "all or virtually all" of the parts and processing must be of U.S. origin. The product should contain no — or negligible — foreign content. Claiming “Made in the USA” for foreign lifters machined or assembled in the U.S. would certainly violate FTC regulations.

Anything posted on a public forum is not going to be current by any stretch of the imagination.
Even Topline is a crapshoot along with your crappy roller lifters so it looks like we are all in the same boat. Welcome to the jungle gentlemen... |

Australia makes some really nice products too. ICE ignition is one that comes to mind. |

I’m not an expert by any stretch but I just received my Crower Cam Saver lifters and the machining looks great.

Harley-Davidson motorcycles sold in the United States are not actually made here, but assembled here. Harley contracts manufacturing of parts to plants located all over the world, including Germany, Italy, Taiwan, Japan, and Mexico.

With most of this stuff, especially in the hot rodding world, it seems the best most of us can do is buy parts based on reviews from people we trust.
Just pick your expert, or better yet a consensus of experts, trust their opinion and roll the dice! |
Harley Davidson Twin Cam engines used Hylift roller lifters till 2001, then went to cheaper Delphi parts. They are NOTORIOUS for lifter noise and several companies make parts to help quiet them down.
I put Hylift roller lifters in mine plus the "rocker lockers" and it turned it from a "thrashing machine" to a sewing machine as far as noise is concerned. Going by memory 4 roller lifters were right at $160 back then......... |
I was told at one time the most "American" made car was Honda..

Watch Topline's automated manufacturing video and you can understand how the cost of making a lifter (or anything else) might be less in another country. Not sure if this reflects their current process, but I am sure their investment in custom equipment would have to be spread over a LOT of parts. And the market for old Pontiac parts is probably two levels below "a LOT" in their world.

I can’t get a good picture of the machining swirl on the bottom

I'm not seeing an oil hole, so I went to their website, still don't see anything and their description on their "cam saver" lifters are vague, as in they say nothing at all. So why are they called cam savers? I don't see anything different about them.
I used the Comp version that they called EDM at the time and they actually have a hole on the face of the lifter to squirt pressurized oil right onto the cam lobe. |
one time in the early 90's i put in a new cam and lifters, small cam stock old springs decided to spin the oil pump before i put in the pushrods
WTH glitter of copius amounts came flowing out of the tops of the lifters when pressure hit them i have a reversable air powered 950 rpm drill motor i keept spining the pump until the glitter stopped and i was comfortable all the oil went through the filter a few times because at that point the cat was already out of the bag lifters have been sketchy for a long time |

So what makes them a "cam saver" ??? |
Here are the lifters I used, and you can clearly see the .012" hole in the face of the lifter. Squirts oil right on the lobes of the cam.
