JUST MY TWO CENTS WORTH.
I HAVE FOUND THAT MOST ROD FAILER IS FROM
THE BOLTS. I HAVE BLOWEN A FEW MOTORS, WHEN
I INSTALLED ARP BOLS, I HAVENT BLOWEN ONE
SINCE.

I WILL KNOCK ON WOOD JUST IN CASE.

A floating wrist pin is not pressed into the small end of the rod like a stock rod/piston assembly. The small end of the rod is enlarged so that the wrist pin has just enough clearance to turn freely. Some rods are enlarged even bigger and a bronze bushing is installed for the wrist pin to ride inside of. The floating pins are retained with snap rings or similar hardware so that they can't move in and out and scuff up the cylinder walls.
