You didn't read far enough.

The rearend is now back in, we had Moser narrow it 1 1/4 inches per side. Mike at Moser also recommended gun drilling the axles, so we had that done too. They took out 6lbs per axle and it only cost $100, that is a lot of rotating mass!! While at Moser, we did some more calculations and stepped up to a 4:30 rear gear. With the 28" tall tires, and they will grow approximately an inch on the big end, we can run 120 mph at 6000 rpm. Once the new engine is in, this will allow for 140 mph trap speeds at 7000 rpm.
