And heres a good shot where you can see how loose it is, What would be the reason for such loose pistons.



Those old TRW Forged psitons were designed with a lot more room at the top to allow for heat expansion. What is the clearance in the wrist pin area, about 1 inch below the oil ring? I think you will find it is a lot tighter there and that is where they were measured for machining clearances.
