Re: What's going wrong inside my 350?

One time a truck that came in the shop with a similar sound. Turned out the owner swapped in a used engine and used the flywheel bolts from a stick flywheel (too long) on his thinner flexplate for the automatic that was in the truck. The too long flywheel bolts were rubbing-hitting the back of oil pan flange on the block. Easy to see with a flashlight from under the truck.....
