Let's face it, 400M Ford owners get no respect. Sure, mention the word Cleveland and watch everyone's eyes light up, but the fire dies right out when you try to include the Modified or Midland family in the discussion. This seems odd since the two motors share so many components.Let's face it, 400M Ford owners get no respect. Sure, mention the word Cleveland and watch everyone's eyes light up, but the fire dies right out when you try to include the Modified or Midland family in the discussion. This seems odd since the two motors share so many components. In fact, it can be argued that the 400M motors are nothing more than a tall-deck, stroker Cleveland. Think about it-that's all that separates the legendary 351 Cleveland from its torque-oriented 400M (try running that statement by a Cleveland fan some time). Run with the same combination of parts (heads, cam, and intake), the 400M will always make more power than a 351 Cleveland, making it a readily available and ideal classic truck powerplant. Nonsense you say? They key to the statement is that fact that one truck motor measures 400 ci and the other fancy race motor displaces just 351 ci. It doesn't take a rocket scientist to realize that if both have the same head flow, cam timing, and induction system, the bigger motor will always make more peak and average power. The key is selecting the right components for your intended application. More power and torque for your Ford 400M is a simple intake swap away.
