340 engine / oil question

Well after all this time, I got the motor out, old oil pan on, motor with new small high torq stater laied in then motor in and wires to starter to short. So, out comes the motor again, old starter back in, motor back in everthing so far so good. All this with a bad back. ( the oil pickup was hitting the bottom of the new pan) now , cold I have 70psi oil pressure hot I have 40psi oil pressure. And I had 10w30 oil in there before and now I have 30w. Now that that's all done, I'm having a hard time getting the timming set. ( I never set timming on a car, so I have to wait till 1 of 2 people I know can help with the timming.) With a built motor, what would the timming be? Anyone? ( so I will know where to start. Again thanks', Thanks' a lot to all who had any input in this. :headbang:
