Wow, it would help if someone who really knew what they were talking about piped up and put an end to all this speculation !!!

Well, I crawled under the car today and found that the torsion bar cross member is starting to tear from the inside out right near the torsion bar socket. Must have just happened after the motor change.
No way the motor change caused this. The motor is supported by the k- member and frame. The lower control arms are also supported by the k-member. The torsion bars tie the LCA's to the rear crossmeber BUT the only force that is exerted on the rear crossmber in the torsion bar area is "torsional" force - in other words, twist. Furthermore, those cars were built to take 440's and hemi's so look elsewhere for the cause - like maybe the floor is rotten.
If the frame, crossmember, etc is separating from the unibody there will be other signs as well ... there should be some distortion in the inner fenders or firewall and the gaps between the front fenders and doors should be inconsistent top to bottom.
