Drag Truck Part 2 "blackmark redemption"

What range of diff gears did these trucks come out with originally?

2.71 with a 31 inch tyre you arent even going to see much of second gear over the quarter mile!
3.21-3.55's would be mostly what you'd find in a D150. Mine would have been 3.55's from the factory, but somebody swapped them out for the 2.71's. I'm sure I wouldn't get out of 2nd gear in the 1/4 mile, but I haven't really driven it except what you see in the video's because I don't have plates on it yet.
