Are 3.55 gears a good choice?

keep the 3.23 and put in a tight 10 inch converter and then see how it is.

I got 3.91's and love them, the prefect gear around town but yes, 3,500--4,000 on the freeway does waste gas--don't think it really hurts the engines-like a 340 which is made to rev but gas $$$ adds up and traffic goes 75-80 on the e ways
