The mounts are new, I put in the polyurethane motor mounts from Bulter and the trans mount was replaced a few years ago and is still in good shape. This vibration is definitely rotational due to the harmonics that I feel. I was an auto mechanic for 10 years and have fixed my share of vibrations, but this one has me stumped.
Maybe the reason its worse now with the new engine is because of the stiffer motor mounts, but that still doesn't explain the cause.
