OEM GM solid lifters
What does a set bring in the real world?
Anyone know the hardness & hardening process for the lifters & GM cams?

If you are talking about NEW parts, GM does not make any parts these days....they just buy them from foreign sources and place them in a "GM" box. If you think you are getting 'old GM' quality, think again.

Correct they havent made them forever...think theres still a market for them if quality was known to be good.
I daily drove my 70 Z/28 for years, with the 140 cam beat the daylights out of it....yrs later when al lthe fast ramp craze started had them all go bad back to back and fast. Only then swtiched to roller
Still wouldnt hesitate to use a flat tappet if I knew the quality was there just doesnt seem like theres any standard out there anymore.

The only 'standard' in the auto parts business is MONEY!
Make 'em cheap and sell 'em fast. Let the buyer beware!
And as long as most of the customers prefer 'cheap' rather than 'quality', that's the way it will be.
