Ultra Pro Machining opened their doors in 1994 in response to an almost overwhelming demand from a number of prominent race teams. Ultra Pro's owner Don Losito, after many years of success in drag racing, started his professional race career as an engine builder in the mid 70's. By the mid 80's he was building Cosworth Indy engines with his skills being recognized by many teams. One such team was run by drag race and Winston Cup team owner Kenny Bernstein. In the late 80's Don, at Kenny's request, moved to Charlotte to port the heads and build the engines for his WC team. The demand for his heads was overwhelming to the extent that CNC production of Don's head designs was the only option.
