Finally tore into the truck this weekend.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Figured out what was causing the knocking. It appears the folks who rebuilt the motor didnot torq one of the rod caps very well. The truck has been sitting for a little over 2 years. I have had it almost 5 years total. The guy I bought it from said the motor had just been rebuilt.

I pulled it out with the tranny. My Dad and I flipped it over and pulled the oil pan ans saw the damage. I was able to twist of the nuts off by hand on the bad cap. Bearing was all tore up. Anyway, I may get some pics posted. I am getting ready to put the new motor in soon a a few weeks after I get everything cleaned up and painted. The tranny also has a 1/2 inch thick protective coating of mud and oil.

Originally we thought it was one of the heads, due to what we could tell from the visial damage that we could see and replaced them both with newly rebuilt 350 heads. Got them on fired it up and still was knocking.

Anyway, it is good I have a new block. I am tryin to get some new mufflers too. Thinking about 40 series flowmasters.
