Vinnie is no dummy, so yeah, it's possible.
What we try to achieve is a final drive first gear ratio of around 10.0:1.
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.....
