Here's a shot of the entire Vortech kit for Ford and Chevy. Looks intimidating, doesn't it? Don't worry because some of the pieces you won't use. The kit on the left will fit all '97-'03 F-150s, and Ford has made some changes during that time, so some parts are extra. Between the Chevy and the Ford, the Ford took more time and was a little harder to install. The Chevy's system, on the right, seems a little less complicated, but that is mostly due to the fact that the kit is a direct bolt-on application with no modifications for most '99-'05 small-blocks.

The Final Word
So, who won? Who took out whom? Who was the fastest draw? That answer is not clear, given the sizable differences in equipment installed onto the trucks before the testing. Plus, given the nature of how a chassis dyno loads the truck and the difficulty you can encounter when trying to duplicate dyno testing on a computer-controlled vehicle, it's tough to say which engine actually produced more usable power in the end. If you've ever tried to do back-to-back dyno runs with trucks like these, you'll find that the computer likes to pull out ignition timing when things get hot in the intake manifold, which always kills power output, so the results don't always make sense. The one thing we did learn, though, is that both vehicles showed significant increases down low in the powerband, making the engines very streetable. And the truest testament to both engines' might is that both of these trucks have seen daily trips down the rugged freeways of California, and both have been on road trips to neighboring states as far away as Arkansas, without a hiccup since the addition of Vortech's blowers.
