eghh. terminators are fast. 12.9 at 110. but ls1's are 13.1 at 108. not that much of a difference. ls1's are faster than mach's. a properly drivin mach is faster than lt1. mach's are 13.3 at 104. ive seen stock machs do 12.9, plenty of ls1 owners stock have gone 12.9 ive seen 12.6. termies have gone 12.4 i think most lt1's are mid to high 13's at about 100..
