BREAKING NEWS: We have started. Redid all my injector wiring, even though it mostly looked fine, I think a few of my crimps were bad on the signal side, causing them not to fire. Did an extra nice job, and all was well. Still wouldn't start. Decided to rotate back to TDC. Turns out, the last time I set to TDC, I thought my dizzy rotor was 180 off, so I rotated the shaft 180. It was correct where it was the first time, so I actually made it 180 degrees off. Just moved my plugs and it started right up.
Can't work on it however, as my oil pump gasket gave out, I think I overtightened the pump. Of course something else happens and I can't tune it today. Oh well, at least it starts now. Will take this as an opportunity to turn my shaft to the correct orientation when the gasket arrives tomorrow.
Thanks for the help NewZed, you were right, exhaust stroke, not compression. Will post in my build thread over in the L6 forum when I get the timing dialed in tomorrow. Excited to hear the turbo.
