Need help with old Chevy versus Mopar debate

Before I posted this, I spent a lot of time on the internet trying to find hard numbers. Most of the sites that mentioned the 327 either discussed Corvettes or went right to the 350 and 396. I like the idea of a 1968 Dart 340 v. 68 Camaro 327. I am still trying to find a site that cuts to the chase.
