Hi folks, so I have my 55 Chrysler torn down to the bare block ready for some cleaning and fresh gaskets. My question is..... The upper piston was melted a bit last year from a lean carb, yet it retained 120psi all summer with massive damage. I pulled the powerhead to replace the upper bearing that had gone bad, and found the upper piston to be worse than I thought. So... I bought a parts motor, it has one good low hour piston in it (see where I am going with this).. does anyone see any issues with plugging the used piston into the bad pistons place? The bad piston had a stuck top ring, and massive melting (I will post pics later), and anyone know torque specs for the rod bolts? Its a 1973 Chrysler Model 555HF.
