The worst brand of ft hydraulic lifters

[SGBARRACUDA]

In my experience with flat lobes, most times it was stock or new moderate pressure springs.

I still say anything with the heavy duty snap ring is better than anything with the wire retainer.

Which/what snap ring can replace the wires? Might be a worthwhile investment for the "kit" cams.

Well, thinking about the crappy steel factor, it would be interesting to do some Rockwell testing on a few of the FT lifters currently in the market. Years ago (80s-90s) this would be the test we’d apply when someone had rounded a lobe, invariably the lifters were never a factor then, generally returning a RC of 54-56 (from memory) Generally it was run in procedure or setup that brought on failure. Lifter bore alignment was also an often overlooked issue that stopped lifters from turning (especially in SBChevs)

Not just the lifters but the camshafts also.
