As I posted earlier there is a way to build a decently compressed stock stroke 400. Cut the crank pin to 2.2", Use Scat rod# 6680022(A) @6.800",and either KB 825 @1.480 or KB 828 @1.485. With a 9.98 deck the piston is either 0.010" or 0.005" in the hole, both pistons have a 4.5cc valve relief. Depending on head and gasket combo the CR can be in the mid to upper 9's.
