How much faster are you wanting it?
The EZ, VA, PowerPuck are good starts, mild fueling boxes with some timing. Much more then that and you'll have to pay a lil attention to the transmission, valvebody that turns up the line pressure would help. I ran about 290hp through the transmission with only a shift kit for 15,000 miles with no problems. Now I have a tad bit more power, so I did a torque converter & valve body swap.
Dunno what my 0 to 60 is but I can get to 79. 90 in 8. 519 seconds according to most of my time slips (thats my 1/8th mile time and speed).
