Engine cases are the foundation of your complete engine project and we offer the finest available in the industry. Improved appearance and design features in almost every area of these castings along with their exceptional price make these a must when replacing worn out or weak stock castings.

New Cad-Cam designs produce a
highly engineered efficient & economical product.

Accomplished Engine Designer and Racing Engineer Ken Francis states:
"The big difference between our product now and what we had in the past is that we do have a much lighter reciprocating weight in the engines that don't shake that much. They are in fact, pretty smooth."

"These engines are VERY AFFORDABLE
by efficient design & engineering."
