Vibration around 2k RPM
I have a new motor with about 500 miles on it. I currently have WEVO mounts (blue) on engine and tranny. These were in prior to the new motor. Since I put the new motor in, I get a slight vibration around 2k RPM. Don't really notice before that, and it goes away going up just a few RPM. Never noticed it with the old configuration, but a lot has changed on the motor since then. I do have a aluminum PP and lightweight flywheel.
Normal? Nothing to be concerned with? Todd

Was the exhaust changed?
Is this driving or sitting still too?

Yes, went to headers and 2-in-1-out. So were all internal components and the intake. Definitely driving, need to verify sitting still with clutch in.

Could be exhaust resonance, mine was right at 2200 gone at 2400. What headers and muffler?

Hmmm, hadn't thought of that. They are s-car-go knock offs. 1.75 into a Dansk SS that's been modified by cutting inlets out and welding in 2.5" pipes. Muffler is a bit restrictive. Motor is twin plug 3.2SS, about 299 straight pipes. Haven't tried to drive it with open headers, so not sure about vibration then.
