A stock 'glide has a first gear ratio of 1.76:1, so if you married it to a 5.13 rear gear, the first gear final drive would be 9.03:1, still a little light....
An aftermarket 1.98 first gear in the 'glide and a 5.13 in the rear would make a launch ratio of 10.15:1, mo betta.....
this is the 1st time I've ever heads of gears higher than 4.11. with 5.13 gears if I'm cruising on the higheay where will my rpm sit? high or low. the ideal mph is around 70-75.
when I say drag racing I mean bracket. but Friday night grudge runs aren't out of the pic either. will 5.13's kill my gas more than 2.73's would.
