From Mikek's description it appears that I will pull the pistons and 180 deg them so the tongue is on the cam side. No answer from Macs or Snyders ,I e-mailed them both.Thanks

On the outside of the piston skirt, is the contact area equal on both sides? I've seen some pistons with less contact area on the non-thrust side, just for the benefit of less drag.

Tom I can't tell now because they will be staying in place. I believe they may have been the Silvolite pistons as mentioned by Ursus. Should have her running this weekend.I will let you all know how it goes.

You know the dipper has to point to the valve side. You will have to take the wrist pins out and turn the piston 180 on the rod. If they are all in the same way, I would just leave them like they are.

George, there were 2 right and 2 wrong,and yes I did have to remove the pins and 180 the pistons on the rods. The dippers all face the cam as they should. Just finishing up prior to running her. Thanks for all the support !

If the slot is in the piston yes it makes a difference. If no slot probable does not make a difference. If it makes a difference they should be marked front.
With that said I would put the side that the slot use to be in to the driver side.

The piston on newer cars have the wrist pin off set to one side. They have to go in with the mark on top to the front.
