anyone know the measurement on stock pistons or the stock bore on a 305? I have taken my dream apart and want to rering it but there are no markings on the pistons. Thanks Atlas

I had to go measure a NOS/OEM piston.
My digital mic is MM or Inches.
Pistons are not round they have a larger diameter front to rear than side to side at the skirt..
F/R is 2.360 inches
Side to side is 2.354 inches. .....lm

So roughly 60mm would equate to about 2,375 thousands, give or take a few, I just couldn't resist :-) Cliff
