I've done this twice on each TTA..so 4 times now in 10 years. Pop out the motor mount bolts, jack it up enough to lay a piece of a 2x4 between the mounts or enough to slde the bolt back thru with the top part of the mount on top of the bolt.
Take off the cross over and the flywheel cover.
Then rotate the crank so the front counter weight is out of the way.
Then with a little patience, it will come off, just have to work it around the oil pickup...this part can take a bit until you've done it a few times.
Any F-body is this difficult not just the TTA.
