Lead Engineer of the Z/28 Camaro, Mark Stielow, has just finished another one of his awesome ’69 Camaro builds and it absolutely spits flames, hence the name, Hellfire.
Stielow is known for building track-capable classic Camaros and this one is no different – in fact, the focal point of this build was weight distribution. Once the hood is popped, it’s easy to see that this car has a powerful LS engine under the hood. If you were thinking it’s an ordinary LS9, you’d be wrong. It’s actually an LS7 engine with CNC-ported LS9 heads and supercharger. Built by Lingenfelter and Thompson Automotive Racing Engines, the Frankenstein LS engine belts out a healthy 953 horsepower and 970 pound-feet at the wheels. The blower has been ported and rebalanced to spin up to 15 PSI in order to produce such high horsepower on a factory unit.
Stielow’s last build, Mayhem, had a little too much weight over the front tires, so for Hellfire, Stielow had the whole front clip made out of carbon fiber to shave a whopping 120 pounds. The cooling system was also upgraded to handle all of the track time that this car will be seeing, and he actually went 20 minutes on the track with no overheating issues. Now, that’s reliable!
With all of the modern technology and composites that are used in the automotive industry today, it’s awesome to see them being put to use in classic cars. Check out the video of Stielow shaking down the car at Gingerman Raceway. We’d sure love to take it for a spin!
