Roger I changed from a 3.5:1 to a 3.89:1 with a TKO600 transmission. 347 engine. I changed ratio because the 0.64 5th gear ratio would not play nice with my cam at 55-60 mph. Seat of the pants, not that much difference.

Pick up a part time or seasonal job that you enjoy. You should be able to make an easy $3K over a winter (or summer if your in a desert). Get with KC on a set of heads, intake, and cam. That is a change you will feel in the seat of your pants!
