The areas that need to be lubricated are the moving parts: the connecting rod to wrist pin surface and the rings where they rub against the cylinder wall. Both get oil from the crankshaft through a very roundabout way. Oil is forced into grooves in the crankshaft main bearings through holes in the bearing shells. Holes in the crankshaft align with those grooves and deliver the oil through passages in the crankshaft to adjacent rod journals. As the crankshaft rotates those holes periodically line up with holes in the rod bearings and in turn with holes in the connecting rods. The connecting rods have internal passages that carry the oil to the wrist pins, where the oil is distributed to the oil control rings and is used by the wrist pins.
Pistons are a major part of the engine and if one goes bad there ain't no fixing a piston, replacement is necessary.
If a new timing belt was installed but the valve timing does not correspond with the pistons ie: the valves opening as the pistons reaching top dead centre ,,then it will be jamming.. bending valves and possibly damaging pistons.. when fitting a new timing belt or chain you have to be very careful of cam/valve position in respect of the pistons
pistons in every engine are located in the block

Crankshafts are usually always forged for strength. Connecting Rods and pistons are usually always cast in normal consumer vehicles. Race and High Performance vehicles have very exacting designs and are usually built differently.

No. Standard 350 engines have 4.00" pistons, standard 400 pistons are 4.125".
