Re: Original solid cam vs. full solid roller
The 143 runs like stink.
But, and this is just my opinion, and only because you asked. The less you drive it, the more likely you are to wipe a lobe. I worry about it every time the Z goes more than a few days without being started.
I am sure there are grinders who can get you something very close (with maybe just a hair more thump) to the 143 in a roller cam. Nice peace of mind.
