65 less cubes. The LS1 is 346ci. Mods do alot for the newer cars. With similar mods to your bolt ons I am keeping up with and going quicker than Vipers that have 142 more ci than my LS1. But the Viper can always mod also. I am impressed with the newer 4.6s heads cams and intakes. I know someone who just put them on his 96GT and it was an amazing difference.
