Was talking to friend about this that runs a glide. Figure his first gear is 1.80 with a 3.89 rear ratio which makes him a 7.00 total ratio thru first. His sixty foots are in 1.3 range.
727 first gear is 2.45 and if you use a 3.23 that would make your first gear a 7.9 ratio.
The torque convertor would need to be set up for the higher gear ratio.
