Rebuilding Original Engine 383-s Fastback

I'm not sure what all's been done to that 383, but KB flat tops won't get you anywhere near 10:1. That'snot a big deal, but it will be closer to 9.2:1 depending on the head gaskets and chamber size - but that XE268 is a great cam with it. I've used that a couple times in 383s and never been disappointed.
