James Jordan has been a writer and photographer since 1980. Recall that the engineers of the 1960s could predict airflow through CFD (computational fluid dynamics), deliver fuel via a direct injection system that pulsed the output to assure the best possible mixture, computers that consistently monitored all engine functions that allowed maximum performance under the available condition, or any of the other tools and gizmos available to engines today. The Engine Block - When it comes to building an engine you always start with the main foundation - the block.
