Something else to ponder on. Just because it's made offshore, China, Brazil, Japan, Sweden, Germany, Italy, etc, doesn't mean that its an inferior product. Believe me those Countries and others have the capabilties of making parts just as good as we could do here........just not at the price point we are willing to pay for them...........
Well stated, Cliff. Of the Cummins 6B and 6BT forgings we used to regrind some of the better ones were from Brazil. The best were from Great Britain and Germany. The worst? Mexico. U.S. and Japanese forging were on par with the Brazilian forgings.

Well those goofy laws that vary by state sure seem to leave a lot of grey area.


On the flip side there is a lot of junk out there too, we all know that.
A lot of the aircraft recip engine parts we used were made in Brazil (valves, valve springs, valve spring retainers, and valve keepers), Germany ( pistons and piston pins) and Great Britain( oil pump gears, rocker arm bushings, connecting rod bushings, connecting rod bolts…even SPS bolts, and engine bearings). ALL of these parts have to meet the OE specifications and pass an FAA inspection. ALL nations produce garbage as well as well made parts.

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...

I agree with that. That's what I was getting at in Cliff's post. Just have to sort through it. Just because it's from a foreign country doesn't necessarily mean it's a bad part.
Australia makes some really nice products too. ICE ignition is one that comes to mind.

Yes, our Government gives China a lot of leeway on copyright infringement. But you are screwed royally if you design a part for a diesel truck that improves power but messes with the function of the EGR valve.

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

Can you post a picture of the lifter body?

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.........

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'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

Yep, and if you click on "more information" nothing extra, no info on the lifters. There is literally no description about the lifters at all that says they are anything other than a regular flat tappet lifter. No hole on the face of the lifter either that I can see. 64speed's picture of the lifters he received doesn't show a hole either.

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.
