Slow Z28

All things being equal, can a lighter car work better on a narrower tire? or would it be the other way around. My car will weigh in at about 3150 w/ me in the car. And i have all the bolt ons and a TP4400. Just trying to pick out what e.t. drag. I got a good deal on some 26x8.5's, so i was thinking those. But what would the theory be for weight/tire size? and why? thanks.
