Whoa, those guys haven't seen a lot of folks who lift seriously, have they?! I'm a woman of similar size and can deadlift 250 with a goal of 300 this year. I think of 275 as a decent deadlift, but not freakish for a guy.
A 275 bench is pretty sweet, though. And dude, one-arm pullups definitely mean you're freaky strong in my opinion. Just not necessarily a freakishly strong deadlifter.
edited to add: not necessarily a freakishly strong deadlifter *yet*.
