Well, more like 3150-3175lbs depending on options. Camaro's can be in the mid 3400s depending on options, subtract whatever weight the SS guy took out and boom, both cars are going to be at somewhat close weights, with likely similar power on that race.
I think the race looked good to me. :shrug:
Many people get 3050 out of C5Zs with a half tank of gas. Headers and offroad x pipe drops the weight even more. Curb weight(stock) is between 3115-3130. They also have around 19 gallon gas tanks, so running it almost empty drops quite a bit of weight too.
