If the motor is still strong,I would consider a carb kit and changing rear end gears.Convertibles were meant to be cruisers. The "highway gears" that are in there will never give good performance off the line but will give economy and high speed. Consider a change to 3.55 and maybe a shift kit if you want to get there a little quicker and sacrifice some economy and high speed. Changing from a 2.94 to a 3.21 in my Barracuda woke it up pretty good. A rear gear change could be done quite a bit cheaper than an engine and would help get you to your power band sooner as well.
