Diff ratios and Et's

[A360]

Hello fella's
Sorry if this has been covered before did a search and came up with a 0

Any way I am putting a 9'' in my hardtop (Dart) which runs 12.7@109.3mph
with 3.7 gears.
The ratio going in is 3.55 what changes should I see with the change?

360/727/3.7 M/T street drag tyres 26''

Cheers

you probably won't notice much its only a 5% reduction. If your rpm at 60 mph was 3000, now it would be 2850.

You will probably only loose a couple of hundreds to a half a tenth in ET, not much.
