The owner sent it to <a href=\"http:\/\/v8speedshop.com\/\">V8 Speed &#038; Resto Shop<\/a> in Red Bud, Illinois for some performance upgrades. While there they replaced the factory engine and transmission with a LS3 V8 making 480 horsepower and 4L70E four-speed automatic transmission. The car also received new floors, custom firewall, Vintage Air system, Ridetech Street Grip suspension, Wilwood brakes, and YearOne Snowflake 17-inch wheels.
