It's pretty much common practice these days on a Pontiac engine because the aftermarket hasn't caught up yet, or simply don't care. He's even told me he's called the manufactures on this deal to correct it. Paul made sure of this stuff, especially the second time around.
I'm telling you you're going down a dead end with that deal.

I agree, he knows and does all these things during a build that uses aftermarket bottom end parts. So where are the numbers? It's not in the data that Joe was given. Does Paul have this documented anywhere for process of elimination? Meaning, if he can prove he checked it, Joe and his helpers can strike it off the list for sure. Assume nothing when the problem is persistent.
I agree about too many cooks. It seems a few guys are going in after each other and possibly in a big circle with tuning. Motor should not be missing and hopping like it is, and for days. I can tune or diagnose a really crazy engine in about a day. Maybe not fix it, but at least diagnose the illness. Why is this taking so long to diagnose the shakes? If you could get it tuned and running good like the original install videos, that would give a good baseline. The original videos sounded really strong. At that point, you could move on to what could be causing the noise. If he can't find anything external, he's either got to pull the engine or drive it.
Valid compression test numbers would be interesting. What is static compression on this beast? A 10:1 462 with a healthy roller cam should have around 180-210 PSI.
