When I put my engines together many years ago I put a dial indicator on the valve and adjusted the pushrod length for max valve lift. Then bought that length pushrods. Is this what you call mid lift method?

Do you know of any engines that are running these numbers? I don't believe that the hydraulics will support 1350... I'd like know if some are out there

The mid lift method essentially has you set the cam for half of lobe lift, measure valve lift to half of total lift, and set your pushrod length so your trunion is at exactly 90 degrees to the valve at this point. Bob sent me a picture when I was talking to him about it that helped me greatly with visualizing it.

Not necessarily.

What I used to look for was simply a pattern on the stem that was centered, and somewhat narrow. But sometimes simply being centered is not going to give the narrowest sweep, and can result in a loss of movement of the valve due to wasted motion.

I initially had read about that method a few years ago. I wrote it off as technical mumbo jumbo, simply because I couldn't wrap my head around all the geometry, drawings, and so on. But it's actually very simple, and makes quick work of measuring for the proper pushrod lengths. Bob Madera explained it in depth to me, and it simplified it and helped me understand all of it. You can really see the differences in rocker geometry from brand to brand when doing it that way. The comp cams rockers we tried were the worst from that aspect. Cranes were better. Crower makes back set rockers which is nice if you wanna fine tune things.

FWIW I have 2 seasons on my solid rollers (T&D) and lash is still right where I set them.

Why you ask?
Only reason should be a lot of time on them.
Or the Needle bearing in the tip of the rockers are not rolling anymore.
