Apparently it wasn’t a big deal to make 749 hp and 594 lb-ft of torque from this 8,000-rpm 6.0-liter, which started life as a Ford GT 5.4. “It’s a natural-born horsepower and torque maker. Much like a Cosworth DFV, the higher you rev it, the more power it makes. It’s an efficient basic design. Just like any other competition engine, you have to cam it correctly to garnish all the torque and horsepower you can get in an rpm range that makes sense before getting into piston speeds that could hurt it. The air intake system configuration goes hand-in-hand with that,” Joe Huffaker explained. “There actually is more power available if we squeezed it some more and spun it higher. That would still need to be tested. We know our current combination will go the distance, and most likely could even run an entire season without a rebuild. That, too, was important to this team.” View Related Article
