On this episode of Engine Masters presented by AMSOIL, we test the long-standing Internet theory that too big of an intake port kills bottom-end torque. Watch us take the mildest of 408 Ford small-blocks and try to make the torque curve dance by bolting on three different heads from AFR. Will the myth be busted, or will we stumble upon a surprisingly awesome combo for a small-block Ford? The answer to at least one of those questions is YES!! Engine Masters is supported by Earl’s Vapor Guard hose, Mr. Gasket, Auto Meter, and Permatex.
