gear question

I have a 72 Plymouth duster. It is not setup for street at all.
It's a 440 60 over. 1050 dominator
727 trans 8 3/4 rear,
I would like opinions on the best gear ratio to get it up and going like I want it to.

Thank you, Illstate

It sounds like you are gonna do alot of racing in a straight line. If you were gonna use this as a everyday driver I would say 3.23 or 2.76's but for you i would say 4.10's or 4.56's.

gears?

i see a lot of tuff older cars ( in Australia ) at the track launch real hard then they don't go much faster after 1/2 track , only to get run down top end . iam sure its because of to high a gear. iam pondering this very same question for the diff i am building . i am thinking 3.7 3.9 4.1 max maybe as small as 3,5 for a good mph . then true trac or Detroit locker because its still a street car sort of .
