People forget how quick these early 90s L98 Z-28 are to 70 mph. On the way home from visiting my mom in my TTA...my stepdad in his low mileage 1992 Z-28 L98 with 3:27 gears meet me at the stop light. My car has only 24 grand on the odomenter and his car has always been pampered and garaged with 45 grand on od...so this was a even race in regards to the condition of the vehicles. I brake boosted a bit to around 1-2 lbs of boost and was surprised that my Turbo T/A could only pull about 1 1/2 car lengths on him to 70. The Z-28 really hung with me up until 50mph. People are always yelling about how great the LS-1 is...but I can recall a few LS-1s that did worse than my dad (could be driver...dad is pretty good). I could have boosted better off the line...but I would have sent the tires up in smoke and lost 1/2 sec on my street tires. The specs on the L98 MAP 350 was 340 lbs torque at 3400 RPMS...TPI makes mucho torque off line. I am hoping someday that the "purple haze" Z-28 falls into my hands
