NO, it is absolutely not easier to do the whole motor.I been calling shops about doing my timing set, and can't really find anyone who will do it, they come off with, I could put a used motor in cheaper, or with the cost of that, you could buy a Jasper or PowerTrain with warranty. So I ask the room is it that much easier to do a whole motor than the timing setup?

If you have something else to drive and are at all mechanically inclined, do it yourself.
