Goal Mid-Low 13's?

Thanks for the info, right now im trying to choose between getting a fox body or going with another vintage, but i was wondering about driveability of the car, im using the auto because it will be a lot more consistant than a 5-speed for brackets, it seems that putting a 351w in a 65/66 coupe with heads cam intake carb with some traction bars and gears is going to get alot better results than building a fox even though theres more weight, i thought the combo i gave would net mid to low 13's, well thanks for the help anyway
