I don't think the weight will get you as much as your height. The guy with the fastest bike at Maxton is about your height and was about 10MPH slower than a guy my size (5' 8")riding his bike. Once you near 200MPH staying out of the airstream is important. Your weight may be an advantage in keeping the front end down.
There is a small loss on the bottom end, but nothing that a stock air box wound't fix, or just the taller velocity stacks. I had Carpenter Race Engines do my mods, and I am pretty sure they put in about the most radical cams you can run on the street. I think they are .385 s. Still very streetable.
Everyone should make a trip to the salt once in their life if they can afford it. A membership is about $150 and about $400 in track fees. The trip took me about 30 hours of straight through driving from the middle of Ohio. Total cost for the weekend was about $2000 (food and hotels inc.)
I can only say this about the salt is if you love your bike and can stand rust or imperfections, don't go. The salt will get into everything and start rusting it away. No matter how much you lube, clean or power wash, it will eat it up. I will post pics of what it did to my bike for reference. I'm not a neat freak when it comes to my bike, but I don't know if I will go again.
I will however recommend Maxton, NC. The trip takes me about 10 hours and is relatively cheap. $50 for a membership and $125 track fees for the weekend. On the salt flats, I made 6 runs in 5 days. At Maxton, you can get in 10-20 runs in 2 days. Maxton is also more challenging.
