Orac was born on 22 January 1959 in
Galați, Romania and began playing junior-level football in 1970 at local club
Politehnica, moving one year later to neighboring club
FCM. He made his
Divizia A debut on 22 August 1976, playing for FCM Galați under coach Gheorghe Nuțescu in a 1–0 loss to
Jiul Petroșani. The team was relegated after his first season, but he stayed with the club, helping it get promoted back to the first league after two years. There, for several years he would form a successful offensive trio with
Ionel Augustin and
Gheorghe Mulțescu, together being called "AMO" by the fans, a nickname inspired by the initials of their family names. In his first three seasons spent at Dinamo, he won the league title in all of them. In the first one, he played 32 matches under coach
Valentin Stănescu, scoring a personal record of nine goals. In the
1986 final, under the guidance of coach
Mircea Lucescu he played the whole match in the 1–0 win over Steaua who had recently won the
European Cup. Orac appeared in 26 matches in which he scored five goals for Dinamo in European competitions, making notable performances, such as helping to eliminate
Inter Milan by scoring the decisive goal of the 3–2 victory in the second leg in the
1981–82 UEFA Cup. He also played seven games in the
1983–84 European Cup campaign, scoring one goal in a 3–0 victory in the first leg that helped them eliminate title holders
Hamburg and his side's only goal in the 3–1 aggregate loss in the semi-finals where they were defeated by
Liverpool. In 1989, Orac alongside teammates
Dumitru Moraru and
Alexandru Nicolae were transferred from Dinamo to
Victoria București. In
Switzerland, following an injury, a medical examination revealed he had back problems. Subsequently, he returned to Dinamo for a short while, making his last appearance in Divizia A on 11 May 1991 in a 1–1 draw against
Universitatea Craiova, totaling 308 matches with 54 goals in the competition. Orac ended his career in 1992, after playing one season in
Divizia B for
Unirea Focșani. ==International career==
