Based on some MPH, RPM, Gear ratio calculations assuming he's using a 30" tire with very little % slip. He's either running 136MPH, a 5.49 gear or only really turning it about 6,681RPM's. Obviously we know what his real MPH and gear ratio is, so that only leave a couple things. Either its only running about 6700 out the back or the converter is flat gone and slipping over 10%.
