Found GRP rods for sale, 7.100 long, .990 pin, 2.200 rod size.618 grams . Seller claims they have never been run.
My question is about change in piston to deck height at running temps, and total required piston to head distance in a BMP Aluminum block. What should they be set up at 70 degrees, so they are safe at running temp?
