Well... Picked up my first project yesterday! bought a 1978 400 from a guy I know in town, he said he thought it had a wrist pin knock. After purchase and removal of the oil pan we discovered the knock was from the counterweight on crankshaft HITTING the number 1 piston!
I'll see if I can figure out how to post the picture I took of it.
I'm rebuilding the motor so I think we should be able to get it fixed, but my question is, What would cause this to happen? It is only hitting on one piston, it has been rebuilt before I believe, because the Rods and end caps have been stamped 1-8.
Just curious to see if any of you had ever run into this problem! I will mic it all out tomorrow
