By 1970, Strongbow was working for Vincent J. McMahon's World Wide Wrestling Federation and was now known as Chief Jay Strongbow. He feuded with the likes of "The Golden Greek" Spiros Arion, "Handsome" Jimmy Valiant, and "Superstar" Billy Graham, nearly winning the WWWF World Heavyweight Championship. A memorable match against "Iron" Mike McCord featured Strongbow applying his sleeper hold. But Lou Albano, McCord's manager, interfered by smashing a cast on the Chief's forehead. It was alleged that Strongbow had previously jumped Albano in the locker room, breaking his arm. McCord was disqualified, but Strongbow was cut wide open by Albano's blows. Strongbow settled the score in front of a sold out crowd at Madison Square Garden, beating Captain Lou Albano convincingly.
Strongbow picked up a win at Madison Square Garden in the summer of 1970, shortly after he entered the WWWF, pinning top contender Crusher Verdu, who was managed by Lou Albano.
In 1975, he began feuding with Spiros Arion. Arion, a popular and seemingly unbeatable babyface, returned to the WWWF after an absence and teamed with Strongbow. Arion turned on Strongbow, destroying his headdress on Philadelphia television after he had tied Strongbow in the ropes, and rubbed the feathers in his face. Arion was now a heel, and pinned Strongbow in eastern arenas as he went on to challenge champion Bruno Sammartino.
Strongbow won his first WWWF World Tag Team Championship on May 22, 1972 with partner Sonny King. They defeated the team of Baron Mikel Scicluna and King Curtis Iaukea. Strongbow and King held the title for a month before losing it to the team of Mr. Fuji and Professor Toru Tanaka on June 27.
Four and a half years later, on December 7, 1976, Strongbow won his second WWWF World Tag Team Championship, this time with partner Billy White Wolf. The team won the title in a three-team tournament, defeating The Executioners and Nikolai Volkoff and Tor Kamata. Their reign was cut short in August 1977 when the belts were vacated due to White Wolf suffering a neck injury at the hands of Ken Patera's Swinging Full Nelson.
In 1979, he feuded with Greg "The Hammer" Valentine, who broke Strongbow's leg. The two wrestled all over the WWF circuit, including an "Indian Strap match" at Madison Square Garden on July 30, 1979.
In 1982, Strongbow formed a tag team with his on-screen brother, Jules Strongbow. On June 28, the Strongbows won the tag team championship from the team of Mr. Fuji and Mr. Saito in New York City's Madison Square Garden. During the match, special guest referee Ivan Putski counted the winning fall, but did not see Fuji's foot draped over the bottom rope. On the July 13 episode of Championship Wrestling, the Strongbows lost the titles back to Fuji and Saito, but on the October 26 episode of Championship Wrestling, the Strongbows defeated Fuji and Saito for their second WWF Tag Team Championship reign as a team. On the March 8, 1983 episode of Championship Wrestling, the Strongbows lost the titles to the Wild Samoans (Afa and Sika). After failing in regaining the belts, the Strongbows disbanded.
Strongbow retired in 1985, but would still step back into the ring from time to time, most notably for a legends battle royal in East Rutherford, New Jersey in 1987. In retirement, Strongbow became a WWF road agent and worked in the company's front office. He also participated in a 1994 storyline in which he mentored Tatanka. Strongbow was inducted into the WWF Hall of Fame by Tatanka in 1994. Strongbow's last appearance in WWE was a brief appearance on the November 17, 2008 episode of Monday Night Raw when Stephanie McMahon introduced him to the audience in Atlanta.
Strongbow died on April 13, 2012.
