Here is an add for the GMC Syclone: http://www.sportmachines.com/magrack/autoweek_3-18-91.html Part of it reads: "It took less than 5.0 seconds to run 0 to 60 on our test track. And 13.06 seconds in the quarter mile." This was a test done by GM with a stock Syclone. I do realize that this was done with a profesional driver in the most perfect conditons so for the average joe to run a 13.0 1/4 mile probably isnt going to happen. However low 13's are by no means out of the question. Twelve years later and it's still one hell of a truck!
