Actually I bet it's 9.6. Like he mentions in his first post:
He also mentions the shop opening the chambers a bit and purposely figuring out DCR at close to 8:1 with the custom spec cam. So it sounds like they know what they were doing to me.
And again...I won't knock that shop, but they took the balls off that doggy with that compression ratio. It probably cranks 155psi..and again, that's why he can crank up the initial timing.
