I got a 70 Mach 1 with a 351w. I decided to tear the car apart for a winter project. Pulled the motor and tranny, fixed up front suspension, painted the firewall and clean everything up. Reinstalled motor and tranny and now I have a weird bad vibration in the motor. While sitting at idle the whole car shakes. I did not remove the balancer on the motor and did no internal work to it or the tranny. I had the motor and tranny separated and was wondering if when putting them back together I did somthing wrong. The flywheel only bolts up one way. Does the torque converter have to go in any special way? There was no bad vibrations in the car before I took it all apart. The motor runs great just like it did last fall.

Does your tc have a drain on the face? I did this once, not through a hole in the flexplate, and it vibrated.
Do you mean that you installed the torque converter without lining it up with the hole in the flex plate? I wasn't aware of this when I installed everything. I will have to check to see if I lined it up. I did fine a pretty good vacuum leak. Going to repair it this afternoon Hope this does it. Thanks for the input
Been there-done that. 
Had a Ford 400 that I'd pulled and stored fora year or so, then when it was reinstalled, had a dead miss. That turned out to be one spark plug that got bumped (heads were removed) and closed the gap. Played hell with my 331 after it was stored for two years and then planted in the Comet.Similar threads
