Pistons, pins, and rings ended up just under 1400$

Pistons are for a 4.570 bore.

Pistons weighed in at 611 grams. Although these pistons don't have oil ring buttons but a special ring that does the same job which saved 32 grams that other pistons would have added on to them. The special ring they give now only weighs 8 grams.

We went with 180 wall pins weighing in at 171grams.

This is a truck pulling engine so it see's 8000rpm for 80% of the run and Gary at J/E didn't want to go any lighter on the pins.
