Suggestions???

[trularin]

Greetings to all.

So last Friday my bride and I were out for a run to eat dinner in the cobra. I had not driven it in some time.

There has not been any high RPM moves since last year and this run was the clean it out before "spring cleaning".

Anyway, I gave it a little while going onto the freeway and the shifter was shaking violently.

I thought maybe the Harmonic balancer had failed ( fuild type ). Replaced that wednesday. That is not it.

So: Engine is Boss 351, B&B, with Ford Boss balancer. The vibe is RPM related as I can feel it with the car parked ( no drive shaft ).

I am thinking I lost something in the flywheel, Pressure plate or clutch.

ANYONE with additional ideas what to chime in???

I want to make London - so this is a fix it now type thingie.

Thanks for any help.
