Are you sure that 400 motor has 9:1 CR with 6X-8 heads?? The 6X-8 heads have a pretty big combustion chamber and even with flat top pistons and the milling, I'd be shocked if you are truly at 9:1.
Yes, I'm pretty sure. The seller Is an honest guy. He spent $3500 on the engine 10 years ago. The block has been zero decked and the heads milled. I agree with you on the 350, it is very powerful and has gobs of torque. Definitely will not sell it.
