Help! Small block 360 has a knocking sound

George Jets said
This diagnostic work on figuring out the Knock with this 360 and 904 transmission is like putting a Big Jig Saw Puzzle together.

All of the FABO members are putting pieces of this puzzle together along with some clues from the OP to keep things headed in the right direction to ultimately solve the problem.

just dont turn all our pieces around or you might find the ones i have have a black back, yours might be green and the OPs are red
