That way you get the beefier rear end and the 3.45 gears instead of the 3.27. That would put your first gear at 15.46:1, give you a bit more pull throughout the entire strip, and help you handle the extra power if you decided to go FI or similar.
That tq multiplication number doesn't mean squat when you take tire size and rev range (7000 rpm) into consideration. 4.10's would be the minimum of what this car really needs. The overall gearing would be VERY similar to when the stock/bolt-on 5.0 guys were putting 3.73's in their 87-93 5.0's.
