Comp Cams XE268H Sold under Part # 20-223-4

problems being....
1.) I dunno if there is any stock available anywhere as post COVID inventories may be depleted ?
and questionable if more will be produced(if ever again), as CWC the Cam 'core blank' company that makes the Cam Cores for CompCams and everyone else has sent out a letter saying they will not be servicing cores for these older engines anymore post COVID.

2.) Most all Hydraulic Flat Tappet Lifters out there these days are merely "re-Boxed" Chinese GARBAGE showing up in everybody's boxes... Comp Cams included.... and there is currently an epidemic of Cam Lobe failures on break in currently occurring because of the Chinese GARBAGE/SHIT Lifters !

So even if you find a Cam ?
be very careful what Lifters you are getting because NO way to tell by the "Box" itself as EVERYBODY is re-boxing the Chinese SHIT into their Boxes.... and there is ONLY ONE North American manufacturer left that I know of being Topline Johnson that you might try buying direct from to avoid the Chinese SHIT Lifters ?
