Odd vibration in my 55, any ideas?

[lob87WE4]

I got my 55 Century out of storage yesterday, and on the way home I felt a pulsing in the foot pedal. It happened a t around 45-50 mph and was kind of like a medium paced pulsing, I could actually feel the foot pedal tapping against my shoe. Seemed to go away as I speed up, at 60 and up it was gone.

Does anyone have any clues as to what in the world is going on here?

Broke motor or trans mount?

Judd,

I checked the motor mounts last night, solid as a rock, so I quess a trip to the trans shop may be needed

If you have bias tires on the car, you might want to drive it for 40-50 miles to make sure it is not the tires causing the problem.

the tires could have been flatspotted or they may just need rebalanced
