5.7 Swap article

The Horsepower episode also had an Indy intake and headers with no front accessories running. I've seen numbers all over the board though. I never really know what to believe. One person said they had just an intake, cam, headers, and performance carb and had a chassis dyno sheet for 340 rear wheel. That sounds like a pretty big gain to me for just a cam, intake, and headers. One other thing I often forget is that the factory numbers are rated "as installed in the vehicle", so running through stock exhaust with accessories, though I don't know what sort of draw the accessories are running.
