67 rcsb vs 99 rcsb both same drivetrain?

So im trying to do some guessing and figuring out to do a comparision. Most of this will rely on your opinion and prolly what youve seen. Say both trucks have the 5.3/ 4l60e and both are running the same size tire and gear ratio. They run on a 1/4 mile track. Who wins? how bad? I know there is a weight difference of prolly 700lbs,buy how is weight distrabution and will aero dynamics take effect for those 15 seconds?
