I have seen people question the reliability of the link bar style roller lifters but never have actually heard of any issues. Is this and old wives tale or is there some truth to this?
Never have seen any link bar issues to date, But we see alot of lifter that are under size for some reason, That being said we lifters that are a .841 OD and GM lifter bores run .8438 to 8443 which will give you .0028 to .003. which is way to much. And having lifters in there rocking around that will break after a while.
If you don't have bore gauges measrue a flat tpappet lifter to compare the size differance and go rom there.
Wre like to see .0015 to .002 lifter to bore clearance!!

That could explain why some of the really high end (read very expensive) builders install bronze lifter bores?
