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."
