Remember these LS1 guys run at or below sea level. Most of the tracks in the midwest are aound 2000 ft. That is good for a couple of mph.
Why do you think they get the best magazine times at E-town?
BTW, here in Detroit my old 88 350 GTA had a slew of bolt ons. intake, headers, exhaust, pulleys, cold air, TB, 2800 PI convertor, 3.70 gears, and drag radials and it ran a whopping 13.8 @ 98-99. With a low 1.8 60 ft.
You guys in Florida just have a good fast track. Great for comparing slips on the internet.
