New cam issues,

RustyRatRod said

Yeah but who's to say upon replacing the weaker springs with the right ones it won't wipe lobes? In fact, nowadays with any brand flat tappet, who's to say it won't happen? What I am seeing is there are way less failures with solids than hydraulics, but that's just me. I don't know about everybody else.

If I count the 602 crate motors we see more failures with solid flat tappets as a percentage.
To be fair most of the solid flat tappet cams we see are fairly agressive circle track profiles. No rollers allowed except in the 604 crates. They are broke in on breakin oil with the correct procedure and most of the time breakin springs or rockers. The hydraulic flat tappet 602 crates are a mild profile cam with light spring pressures. I hope I don't jinx them but we never see cams or lifters fail in them.
