With car stopped and clutch in, the engine sends a vibration throughout the car and steering wheel at 1000 RPM's and about 1800 to 2000 RPM's. Car has a ProCharger s/c and an MTI B-1 small cam. Do you think it is motor mounts or???

 

Yep, This is were it gets dangeros. Get underneth car with a big big big pry bar. when sombody in the car making it vibrite, pry on the block and trans by the mounts. When vib goes away thats your bad mount. Sorry about the spelling, my high school sucks. PS. works on the exhaust to. that could cause it also.

 

I had an old style ASP pulley that started coming apart and gave me a vibration. Just a thought.
