That would be using the 6.358 stock length rod. To run the .990 pin version, you would have to bush the small end of the rod. Bushings are available too.

I've had a few PM's about compression ratio with the flat top pistons. Zero deck, 9.9cc composite gasket, and a 4 cc valave pocket figures out to this:
84 cc = 10.03 to 1
88 cc= 9.67 to 1
