Chad - In the stand-up game I would make sure and use your height and your reach advantage. Keep him on the outside at the ends of your punches. In Boxing we learn that the best thing to do when against a taller man is get inside his reach and bang away.
Plus, he may attempt to bully you, he's going to have an easier time pushing you around actually because he can get up under your arms and lift and push back or pull forward. Low center of gravity works wonders when attempting to wrestle. Being that he's the same weight he might be more muscular, or just fatter, but either way he has more compact use of his bodyweight.
I would keep him on the outside and make him burn a lot of energy to get in close to you. Sprawling when he attempts to take you down in the beginning. Lots of leg-kicks, as your legs are going to be longer and easier to hit him with. Don't necessarily be quick to give up your height and bend your knees too much to fight on his level, that would be precisely what he wants, for you to fight "short" and out of the scope of your natural physical attributes. Jab him into oblivion and set up your shots. Also hit his body from the outside so even with it taking more energy to get close to you, it'll still hurt him to breathe with a sound body-attack. On the inside, knees. Use your long legs to your advantage and knee the bejeezus out of him. And lastly, develope a frightening uppercut. Shorter guys don't usually see that punch coming.
Good luck man.
