No hurry for me. I actually have a 89 model year 360 LA TBI engine sitting here right now and all the Magnum serpentine parts. I was thinking I may be able to mock it up for you but would need to know if your thermostat housing location is the same as mine. The only thing in your swap that I can think of that would not be perfect would be the bypass hose, but that does work it just ends up a little crooked.
