2000 Pontiac Firebird Trans Am WS6 with T-Tops. WS6 code is on the door sticker .Mildly built LS1 5.7L engine and automatic transmission with 3.73 posi rear. It was built to be driven, not a race car. I only drive it on good days and sometimes to work and back which is 32 miles one way where I average 17mpg. One time I took it on a 2hr trip it averaged 23mpg with the cruise control set at 70mph for the most part of one tank of gas. I've always used premium gas as well. The engine has had an upper half build with the LS1 hot cam and matching springs. The transmission has been upgraded with a shift kit and converter along with a new heavy duty SFI approved flexplate. The rear gear has been upgraded to a 3.73 ratio with the stock posi unit. The exhaust has been changed out with full length headers, off-road y-pipe, flowmaster muffler and polished stainless intercooled dual tips.
