Advice on potential gear swap

Yes, take-off definitely gonna be soft but not hot rodding/racing at all. Really just going to local car shows but some are a little farther away and require longer/freeway drives.

Few more engine/tranny specs I should have included earlier are listed below.

360 mag - 30 over
370hp @ 5300rpm (estimate, car has not been on dyno yet...plan to dyno soon though)
9.5:1 comp
Upgraded/aluminum planetary gears, servos, and accumulator (front & rear) in 727
