The Ford 351 Cleveland Platform

The Ford 351 Cleveland has earned its reputation among serious engine builders for good reason. The factory cylinder heads feature large, canted-valve combustion chambers that flow well beyond what most small blocks can match. When that head architecture is paired with increased displacement through a stroker combination, the Cleveland becomes a platform capable of significant output - particularly when forced induction enters the equation.

408 Cubic Inches with a Blower and Methanol

This build takes the Cleveland to 408 cubic inches using a stroker rotating assembly, then adds a supercharger running on methanol fuel. Methanol's high latent heat of vaporization provides a substantial charge-cooling effect, allowing the engine to run more boost pressure than it could on pump fuel. The fuel also carries oxygen in its molecular structure, which means more total energy can be released per combustion cycle.

The combination of increased displacement, positive-displacement supercharging, and methanol fuel creates an engine that produces power across a wide RPM band. The blower provides boost from just off idle, and the 408 cubic inches give the engine enough airflow demand to keep the supercharger working efficiently throughout the range.

Engineering for the Application

Running a blown methanol combination demands more from every component in the assembly. The bottom end must handle significantly higher cylinder pressures. The fuel system must deliver methanol at roughly twice the volume of gasoline. The ignition system must fire reliably in a high-boost, high-compression environment. Each of these systems was addressed in this build, and the result is an engine that runs with the kind of controlled aggression that the Cleveland platform was always capable of delivering.

This video captures the engine in action - a purpose-built combination that demonstrates what the 351 Cleveland architecture can achieve when every component is selected with the application in mind.
