744F Performance ?
The FAI recently declared the C5M (with new uprated CF6 Engines) broke several time to climb records including a brake release to FL390 with a 80,000kg payload in 24 minutes.
Any ideas on how the 744F with a similar payload would compare ?

Hard to compare without knowing it's take-off weight compared to mtow. 80T payload with a small amount of fuel or with a large amount? Big difference.
744-wise did sea-level to 450 with about 20T cargo and 25T fuel in 18 mins. Not that we were in a hurry trying to set a record.

Why go to 451? depends on whose bean-counting rules you're using. CFP says 451, no particular reason not to agree with CFP/PLOG/Flightplan ... 80 mins sector, 744-wise near as dammit empty.
