Terry,
I would not recommend running the car while it's up in the air. My 392 is running an fairly aggressive roller cam and this car shakes way too much to trust it to jack stands.
Since this dye you are adding to the
oil will take a little time to circulate, why not just pre-arrange with a local shop to drive the car there on a Saturday morning and have them put it up on their lift? Bring an extension and plug in the black light. I'm sure the mechanics will dig looking under a "real" car for a change anyway!
Good luck!
