A Ford guy here...

Jay Leno has a '66 7 Litre Galaxie that recreates one that his father bought new, and he subsequently totaled when he was 16 or 17, same color too, but his boasts a Roush Racing built 514 big block, fuel injection, and a 6 speed stick. I would love to see that car up close.
My old Galaxie was born with a 289 automatic, the 351 that my brother built was around 11.4 to 1 compression, balanced, blueprinted, etc. would easily rev to 7000 rpm. It was estimated to make around 420 hp, which in the late '70s when he built it was pretty serious. Unfortunately the quality of fuel dropped to the point where it would barely run without octane boost, so I ended up de-tuning it to make it driveable, as it was my daily driver in those days, at least in the summer. It was still pretty stout, but had far less cam and cylinder pressure.
