Question on Comp Cam Rockers 1622-16

NS1RM21, had TWO same part number Comp cams go bad on his run stand. Back to back 2 weeks apart. Both from summit. Got refunds for cams on both. IIRC, the mild 268 cam.

I had an NOS late 90’s era Mopar Performance cam I sold owner since I flet bad for him.

Almost year later all is fine.

Ns1rm21, just fired up a Barton/Bullet cam on his 528 Hemi with expensive tool steel flat tappet lifters. No problems at all.

One of the top machine shops around here told him lot of bad quality parts with these buyouts and mergers
