1971 Dodge Demon Firewall Install

Project Garage

By , Photography by

Safety is your responsibility. You can ponder this sentence now, or as your flaming race car without a firewall careens toward the guardrail. We chose the former, and as the completion of our 1971 Dodge Demon project car draws near, our hand was forced to address all the safety gear we might need to avoid CPR at the racetrack. The obvious starting point is the firewall install. The firewall prevents fire from burning you.

If you are not familiar, our 1971 Dodge Demon is a back-halved street machine we found on Craigslist after its former owner got in over his head and bailed for Florida. We were wondering how to finish it, when Chris Alston, owner of Chassisworks, mentioned that he had a matching front subframe that would hold virtually any engine, slam the whole thing to the ground, and shave a lot of weight off the car. We signed up. That led to an eBay G3 Hemi score with a 727 TorqueFlite from Performance Automatic, and a set of big-ass, rip-snortin’ turbos from Comp Turbo. The glorious collection of parts crashed into the firewall, just like Alston said it would.

Up to that point, we had welded and screwed this car together in the saline and mostly useful Car Craft tavern/shop. The firewall, however, required tools like a metal bandsaw, a slip roll, and a bead roller. For the firewall install, we needed a joint with tools above our level of mangle engineering. The guy with the goods was Jimmy White at Circle City Hot Rods in Orange, California. You might remember him, as he also helped to build the headers. Let’s watch as he shows us what to do with the firewall install for our 1971 Dodge Demon.
