That Racing Channel brings this insane Viper taking down worthy competitors all while sporting a stock engine! This build is an impressive testament to how strong the stock block is for the Viper. Calvo Motorsports built this particular Viper with plenty of venom thanks to a twin turbo setup. Watch as this Viper takes down a fully built Evo and Supra!
a V-10 against a V-6? And HOW is this Fair???
