Get something like a Yank 3000 rpm stall convertor. That will also help with towing to get the RPM up a little bit when taking off with the trailer. Be sure it's got a good tranny cooler, also. Just like the Chevelle you have to get it to launch. Since you have a 2.6 60' time, imagine what it will be like once you get a 1.8 60'. You are already into the 14s just by working on the launch. Gears, posi, converter, Calvertracing (caltrac) bars and good tires.
