Living with 3.91's

Well, thanks for all the perspectives guys. No definitive outcome so i guess i'll fit them and see.
I live in a remote part of the UK which means travelling a 500 mile around trip for the annual Mopar Nats.That aside, i really just use the car for local fun, shows and the occassional drag race.
Given the escalating rise in fuel prices, I might as well stop compromising and get the car into the 13's and enjoy it.
One of these days the government is going to make these cars too unpleasant to own
