No pictures as I have not had that done nor do I know any one that has , sorry.
I had 9 secondPhils pistons hard anodize after they got beat up in the motor I built for him instead of buying new pistons, he had Ray Barton hone his block after I sent the pistons back to him to get the clearances correct
That process did add a little more diameter onto the skirts as well as make them tougher Most of the Top Fuel motors have that done to their pistons to help them live longer, seeing that gave me the idea to have his done
