1080+192(fuel)+220(passenger)=1492 lbs,
without a pilot.
Were you a newborn at the time? ;-)
Van says empty weight should be 905-913. Admittedly, not many even come close to that, so unless someone used a higher number for gross weight when they got their a/w certificate, plus-sized passengers are going to be a problem from a legal standpoint, if nothing else.
I've owned two -4s; the 1st was 930 empty, and the current one is around 910. Both are O-320/wood prop a/c. Back when I'd just bought the 1st one, with only a few hours in it (lots of T-18 & Swift time earlier) I unknowingly took up a 235 pounder (he was...densely packed). Let's just say it was an adventure, getting it back on the ground. I was never in doubt that I'd get it right eventually, but he sure was, and he had been a back seater in F-4s.
Since then, with a lot more experience, I've flown several 200+ lb passengers. But absolutely no acro, no short strips (for takeoff), and caution on landing. With that much weight in back, the wood prop versions change from being pussy cats to demanding respect. Pitch forces get a lot lighter, even in normal flight. The 360 & metal prop will obviously help CG, but really eat into gross weight.
If you ignore the legal implications, and you're a good stick (in *that* plane; I've had a Marine fighter pilot scare me in the -4), then it will fly with 200 lbs in back. If it's a c/s prop, that obviously helps with takeoffs at high weights.
