360 LA squeel / scraping noise like drive belt on passenger side

The dude that put the motor together may have put the rods on the pistons backwards. There is an inside edge and an outside edge, or to say it another way, one edge of the crank end of the rod is chamfered and the other edge is flat. The flat edges always face each other in the middle of the journal and the chamfered edges always face the counterweight. If you look at the outer edges of the rod journals on the crank, you can see why they have to be that way. Might not be what caused the problem, but it is a place to look. Sorry for your troubles. :(

Good to know. We are putting a new crank/bearings in the engine, as well as rods and bearings. My son wanted to do rings as well for the experience altho we were told they were already done. Also what you are saying may explain why it looked like the rods had been rubbing the crank... looked shiny on both sides of the rods and crank, prob shouldnt do that? See the edge in the pic, should that be shiny like it was rubbing?
