The greatest advent of the 21st century must be the concept of "supersizing." For only 39 cents you can go from a mere 20-ounce soda and regular fry to a bladder-challenging 44-ouncer, plus all the saturated fat and sodium your body can take with an extra-large helping of fries.

The fact of the matter-super-sizing is anything but new. Hot rodders have been swapping anemic small-displacement engines with larger displacement engines since the early hot-rodders saw an early Hemi and thought it would make for a mean Gasser.

The folks at Mopar Performance have known this all along, and last month we brought you the dyno test results, validating Mopar Performance Parts' 360ci/380hp Magnum crate engine ("Crate Expectations," March 2003).

But as we all know, with super-sizing, certain accouterments are necessary. Where are you going to put that 44-ounce soda? You need a bigger cup holder from your local Wal-Mart. And you'd better make sure the rest room stops are a bit more evenly spaced on your own personal Hot Rod Power Tour!

We knew the outside measurements of the original 273 V-8 found between the shock towers of our project Barracuda would accommodate the 360/380hp crate, but we also knew we'd need to beef up the drivetrain.

In the pages that follow, we'll not only install the engine, but also provide you with the list of necessary components that afford complete reliability to our project. That fits well with our goal of invading the Hot Rod Power Tour in 2003. In fact, we offer details on how you can join the Power Tour and possibly qualify for one of the seven "Coolest Mopar" awards we'll be granting to Hot Rod Power Tour participants who bring their Mopars to one or all of the stops.

Product Focus: Serpentine Accessory Pulleys From March Performance
A street bruiser like the Project '67 Barracuda requires three ingredients-reliability, comfort, and performance. To determine how to drive the Classic Auto Air A/C system and all other required accessory drives, we chose a serpentine-pulley system from March Performance. Part numbers 40415 and P475 were chosen on the advice of March's Randy Killingbeck. Randy also provided us with the following technical information required for the installation.
