Summit97 is an unknown quantity at this point
Default 670 non HO bore size

I can't find any info on what the bore size is on a 670 non HO cylinders. I'm rebuilding a 97 670 motor and bought used cylinders. I want to measure the cylinders to see what size of pistons or if I have to bore them out. If someone could help me out that would be great.

Stock bore is 78mm, same as the HO 670.
