Oh, and the only engine I've experienced with a mis-matched flywheel imbalance factor vibrated even at idle. Yes, it was very faint at idle, but you knew something was way wrong well before 2000 rpm.
By the time you were at just over 1000 or so you knew there was a distinct balance issue involved.
Does yours just start at 2000? Can you feel it at all at lesser rpms? If it's still an imbalance, maybe it's more likely the damper than the flywheel because it's lighter and smaller diameter?
I'm guessing not in your case, because you've already said it was the damper that came with the engine, correct? But the lighter impact of the damper vs the flywheel would seem to indicate that a mismatched one would have less of a severe impact at lower rpm levels anyway.
So what else was done to the engine? Nothing? Just pull it from the donor and install it?
Does the frequency or amplitude change when you push in on the clutch pedal?
Ooh, ooh! What about something simple like the cylinder head hitting the firewall? Or the shifter hitting the floor?
Seems like just a little shifting of the trans to fit the mount would not be enough to do this, but that cylinder head is pretty darn close to the driver's side firewall to begin with. Maybe yours is hitting some linkage or other, or some bit of the casting is touching the body.
Worth a look anyway.
Good luck.
