351W Vibration....:(

Hey folks looking for some feedback...

I have a 69 351W rebuilt and balanced. Street Dampener externally balanced 28oz, Brand new Ford Motorsport 28oz flywheel. King Cobra Clutch Kit. New T3550.

Anyways have a vibration that comes in @ 1500 RPM or so and seems to clear up around 2200 RPM..... also under acceleration there is somewhat of a vibration under load....

One more thing is it grinds when heading into reverse, I have to put it into 1st thru 4th first to get it to not grind... I have already put the car up on stands and stepped down on the clutch and it is disengaging (the wheels do not turn while in 1st).

I am beginning to think the pilot bearing is going south and or the bellhousing is misaligned...

Thanks in advance.
Steve
