Another thing to check is to rev it to the 2600-2800 RPM while parked, see if it vibrates. That will also tell you if it's engine or chassis related.
Usually, if it's RPM related, it's engine related, if it's speed related, it's a chassis issue.
I've seen people have pulleys and fans out of balance that they kept swapping for config to config, car to car, and it followed them.

New engine has new balancer, water pump, ps pump, and alt. I was just playing with the timing up to 3000 rpm and it runs smooth while setting the timing. But i did transfer over the pulleys, they were bead blasted and repainted, and look to run true on the engine, but I give them a closer look while running. Thanks
