On my 360 before I put my oil pan on there are four maincap bolts that have threaded holes in the end of them,is it for a tray and do I need it?

Yes, the four threaded main cap bolts are for a windage tray. As far as need, you'll have to decide that depending on what kind of RPM's you'll be turning. Oh, and a 273/318/340 windage tray won't fit a 360 either.
