Do you have a timing light? It's extremely simple and might even drop a tenth or so off your ET.
Since it's an automatic, i'd say you're doing pretty good (i thought that was 5 speed times). How do you shift? Do you know about the "1-2-1 shuffle"?
I wouldn't just jump in and say do a 5 speed swap, but i am biased towards 5 speeds, i just think they're more fun. However, with a shift kit and the right torque converter an auto can be lots of fun.
i can get a timing light from my work.. nah i have always had a 5 speed up until now so yeah i'm biased to 5 speeds, but now i'm looking into manual valve bodies, torque converters, shift kits, and things of that nature so i might be staying with an auto..
and i don't know about the "1-2-1 shuffle" what is that?
