Solid roller cam Vs Hyd flat tappet

well, I USED to be a fan of aluminum rockers. They definitely have a lifespan.....or a cycle life. Here's a a Hughes after 5 summers. Granted, my spring pressures are 640ish, open.

I was told that at some point Harlan Sharp was making those rockers. If so, the geometry is far from ideal.

It looks like you have a correction kit so that eliminates most of that.

I’ve run Crane rockers at 340 on the seat and 900 over the nose and never failed one.

Of course, if you could still get Norris stainless rockers they were the cats ***. And the geometry was better to start with.

It’s never very good with an offset rocker.
