He was a first-team regular for West Ham for ten years, missing only the 1976-77 season due to injury. He played as a defender, replacing Billy Bonds as right-back after the latter had switched to midfield. He made his league debut in October 1970 against Blackpool.
McDowell joined Norwich City in August 1979 for around £90,000, making his debut in a 4-2 win at Everton on 18 August 1979. He made 45 appearances for the club, scoring one goal. He joined the staff at Norwich in August 1981, coaching the reserve team, but left in May 1982 to become assistant manager at Bristol Rovers.
