400/800, 1:19 is a nice 600 time for a guy that's been training as a sprinter and only has 48 speed. You'll be highly limited with only 22-low speed, that's barely good enough for a mid-major, but 1:19 could open some doors as a development prospect at a big program. Could probably run sub-1:50 at the right school. Check out Iowa State, Penn State, Texas Tech, Iowa, Texas A&M, Indiana, Clemson, and Florida. Those are the best 400/800 schools right now, one of them might be willing to give you a chance. If not basically any SEC, Big 12, or Big 10 school will have a decent program and many would give you a spot.
Edit: Looks like you're in Indiana. Reach out to the Indiana coach, you might have an easy time transferring credits there and they have a great 800 program.
