10W40 will make a difference, hell just throwing in 1qt of 60w into what is currently in there will probably bring it up in about 30 seconds. Since its just rebuilt y9ou may be running large clearances and need a thicker oil, just go thick enough to get good idle pressure though (10psi) and leave it at that, too thick of oil can cause other problems too, especially on a street car that can see short trips where the oil doesn't get hot enough.
