Update time. Things are going slow, but I'm taking the time to further understand the rocker geometery. I modelled the valve train in Solidworks and found that by increasing the push rod .100", I have increased lift by .0065" and brought the rocker to proper geometery. The roller tip rolls a total of .025" across the valve tip.

I rolled out my old 351 and found that it had the .100" longer rods I needed and they are quality hardened rods with pressed in ends instead of the welded balls. The guide plates were also .010" less in width to improve the rocker centering on the valve tip.
The dial indicator confirmed the modelling exactly.

The cam card shows lift at the lifter as .321" and at the valve as .512" with a 1.6/1 rocker, but actual measuring is .5342", so it's better than originally thought.
I got the bottom end sealed up and the heads are on.
I sent some parts out for ceramic coating. The top of the intake is ceramic coated and the bottom side has an insulating coating done.


The finish wasn't as shiny as I hoped, but Mothers Billet polish brings it up beautifully. I'm only half done so far.


The exhaust is also ceramic coated and the inside is done with a different insulating coating. It will keep the exterior from loosing it's brightness and keep the heat in the pipes. Yes, I even did the cat, but Shhh, it's a camouflaged straight pipe.


I ordered a new dogbone, so I hope to have the engine put together on the weekend, then redo the tranny lines before it goes back in.
