The torque will be coming out early this week. I need this problem fixed by next weekend. Take the torque back to the builder to make sure its balanced. Or maybe put the old torque back in and see if they don't back up with that one. Like i mentioned using this engine (636ci) and the old trans and converter we made two passes and everything was fine. One pass with the new trans and converter and all 4 bolts came loose with red lock tight.

Bore is 4.500
Stroke is 5 inch.

Engine has a solid elephant ears, solid mid plate and rubber on the the rear of trans.
