Reversing an offset/production piston

On a flat top piston u only have to reverse the piston on the rod.They are slightly noisier.340S HAVE .100 pin offset, 318s the same till they went to pressed pin, all other mopar V8 still have some offset.I do this trick with any factory piston that Iam using over. The reasoning being there is less friction because of the change in offset.Newer jobber pistons do not have any pin offset, but are a slight performance increase. When swapping hi comp pistons(factory) bank to bank u will gain 2 tenths in the .25..........This trick also worked on brand x stuff, but not as well because off less offset........Kim
