Lubowe, the three-time Academy League champion, said his title was sweet. He finished third last year.
He said he used two strong dives at the start, an inward one-and-a-half and a front double pike, to seize control. He finished with 472.95 points, ahead of Bodnar with 421.25.
"It feels great," said Lubowe, who also captured the Santa Margarita Invitational last month. "It hasn't really sunk in yet."
Thorsness was second by a fingernail in the girls' 50 free to Kiersten Shew of La Serna. Shew touched in 24.76 seconds, Thorsness in 24.77. Thorsness' time also was just a fraction off her own school record time of 24.72.
Thorsness was that close to becoming the first CIF swimming champion in an individual event in Costa Mesa High history. The Mustangs' lone event win at CIF finals came in 2005, when Mesa won the 400 free relay. That relay included James Fowler, Evan Spencer, Adam Douglas and Kellie's older brother, Kyle Thorsness.
Kellie Thorsness said she injured her left elbow during preliminaries on Wednesday. She popped it back into place but then she ended Thursday's 50 free championship heat with a left-hand touch, which may have cost her.
"It was kind of a weak touch," said Thorsness, who was still happy overall. "[The 50 free] was a good race. I feel like I did the best I could. I'm just really excited to make top three. My goal was to get top eight … I'm satisfied."
Thorsness, who was sixth in the 100 free after preliminaries, came back to finish a strong third place in the event finals with a 55.07.
Other Costa Mesa swimmers also did well. Senior James Lewis finished fifth in the boys' 200 freestyle in 1:50.29. Lewis was consistent in CIF; he was seeded fifth headed into preliminaries, finished fifth at prelims and was then fifth in the finals.
He then finished ninth in the 500 free in 5:03.35.
