It sounds like you are ready to fire it up. If the timing is close, it should start. What you don't want to do is crank for minutes at a time. The cam lube will be wiped off the lobes before it starts if you crank to long. Once it fires, set the timing where it sounds ok and let it run for the proper time. Once broke in, go back and set all the details. Use plenty of break in lube or use diesel oil. There has been plenty wrote about this so search for it if you all ready haven't. Go to your GM dealer and get a bottle of engine oil suppliment, this stuff really works! Good luck, Joe.
