With the old V8s, they're running 7.5-8.5 CR back when the emissions hits were starting to come on. So, we can stroke the crank a little and use a little more rod, and be close to zero deck and up the CR to around 10:1. The crank only get's stroker about 0.211" and the rods are about 0.750" longer. You should see how deep in the hole my pistons are with a 8.5:1 CR and a 62cc chamber.
Those numbers are just estimations, different crank stroking needs different rods.
