We’ve long been led to believe horsepower is what “power” is all about. But horsepower is rooted more in Madison Avenue advertising rhetoric than fact. In the power picture, horsepower doesn’t count for much, especially on the street. What counts is torque and when you have the most of it. Engines make torque when you […]
Ford 351 Cleveland Power Build: 600 Horsepower
When I proposed building a 351C for this book, Jim Grubbs of JGM Performance Engineering hauled out a fresh D2AE-CA four-bolt main block and boldly suggested 600 hp at 7,500 rpm. That’s when I contacted Alan Davis at Eagle Specialties for a 4340 steel crank, H-beam rods, and Mahle forged and coated pistons to fill […]

Ford 351 Cleveland Engine Guide: Exhaust Systems
As much as we’ve complained about noise ordinances in the years since “back in the day,” people are finding noise just isn’t cool anymore.
