Having replaced the stock cam in my LO5 with an LT1 cam, I was curious about the difference between the LT1 cam and the police version LO5. I looked both up, and the difference is about .003 on the intake and .005 on the exhaust, with the LT1 cam being slightly taller. They are so close, that they should both have almost equal performance. The chip and injectors from the police version of the LO5 should be suitable for either cam. I do not know if the chip would work correctly with a larger TBI, and headers. The larger police Y pipe would work well with the LT1 cam as well. You could even smooth out the stock TBI to get a little better flow.
