Simple solution really. Remove whimpy 260, install 350 or bigger!! ALL WILL BE RIGHT IN THE WORLD after that!!

All kidding aside, Oldsmaniac is right on all accounts. I did have a torque converter bolt come loose once (probably not tightend correctly after the tranny change) and I thought the bottem end was about to fall out of the car.

Another way to see if you have spun a rod bearing, is to pull the plugs and do a compression check on all 8 cylinders. Granted its a little more work, but it will give definitive results. The one that has MUCH LESS compression than the rest will be the bad boy.
