The 6-foot-2, 315-pound Moala said he doesn't have an offer from the Cardinals but is wanting to visit and is "very intrigued."
"We're working out a visit and they said they would see how things go," he said. "I didn't know much about them until recently but I know they have a new staff and they are going into the ACC. So there's a lot of new stuff with them."
Moala originally signed with Arizona State, picking the Sun Devils over Miami, Fla., out of Serra High School in Gardena, Calif. He attended school at Arizona State but was dismissed from the team for a violation of team rules.
In 2012, Moala finished third at Cerritos in tackles with 49 and had 7.5 sacks and then had 55 tackles and four sacks as a sophomore. He has two years to play two years at his next school.
"It's humbling," he said. "Getting a second chance is something I look at as special. It would be a great experience because I know Louisville is a program on the rise."
Moala is also looking at Oregon State, Hawaii and Kansas State among others.
