We put both engines on the dyno to see which made more horsepower and torque. It didn’t go as planned. Over the past year, we assembled two very mild small-blocks aimed at the typical hot-rodder ...

Turbos and superchargers have made extra power almost easy to come by. Thanks to them, even tiny four-cylinders can make the type of numbers that used to be reserved for big-displacement engines. That ...

Testing. It’s the backbone of hot rodding, and it’s how we separate facts from fiction. It’s also where we generate even more questions, which often results in, you guessed it, more testing. The ...
