Actual calculated static CR is 9.98:1. 467" (455 with a 4.200" bore and stock 4.210" stroke), 430 CBHP @ 5100 and 530 CBTQ @ 2900 on 93 octane pump unleaded.
Looks (and sounds - except for the solid lifter music) like a stone stock HO under the hood, manifolds and all.

Thanks Lloyd,
I was curious because my engine was originally put together almost 20 years ago and it has TRW domes in it.
Had it on the chassis dyno last fall 380 HP @ 4900 480 lbs ft @ 3400
running very lean.
I didn't have any jets with me to correct it at that time.
I will be making another trip to the dyno this spring hoping for some better numbers.
Thanks
