Engine shakes BADLY!!

As far as engine cylinder test. The engine is bran spanking new again. And the compression tested ect. All good.
As far as timing my engine builders tech was bored and came over to help break it in. He gets paid to do this for side work, so I'm confident he knows his stuff. Initial is 18*,34 total. Runs hard and strong. Plugs read good. Maybe a lil rich on the porcelain.
Idle screws work. I'm about 7/8 out.(turn).
All wires/ plugs are good. Just checked that due to a different story when I pulled the engine.
Only other problem is engine is getting hot. Don't wanna get off topic but runs cool around 185-195. Until u get on her and just climbs to 200-220 and does not come down after. Stays hot. Even on highway
But that's another problem for another thread. I'm still getting this new engine dialed in 100% obviously. But was trying to get rid of this shake.
I have a big cowl hood and I can see the air cleaner at idle move 1" either direction. Sometimes worse then other times.
I've looked everywhere for a vacuum leak.
