L28et timing verification

So I'm in the middle of a l28et swap into my Late model 260z. The car cranks, gets fuel,spark, but won't. I'm assuming its a timing issues, and would like some verification on a few things.

 

First off is this the 11:25 position of the oil pump rod people on the forums are talking about(using the two distributor bolt holes as a 12 o'clock and 6 o'clock reference)? This IS with the engine at T.D.C compression stroke.SP_A0245.jpg

This is how the rotor inside the distributor sits when fitted to rod position in the picture above. The rotor is facing the front of the motor toward the driver side headlights. Does the positioning look correct?

This is the cap over the distributor. As i am writing this I am kicking my self :twak: , because I am looking at another thread that points out the raised portion on the dizzy cap that indicates the #1 spark plug position. If it is the circular dot on the dizzy cap in the picture below, I may have just solved my problem :lol: Currently i have the #5 cylinder spark plug wire hooked up to the position closest to the raised circular portion.

That doesn't look like 11:25. And the picture above that one helps , but i'm confused as to where I should be measuring the 11:25 from? The two bolt holes or a vertical line like in the first picture?

Forget the "11:25" and make it look like the pictures from the FSM... I could tell from your first pics that your dist. was off. My rotor points much closer to forward at TDC (like the diagram in the FSM).

Thank you, will try. What about the circle part on the dizzy cap? Is that where the #1 spark plug wire needs to be?
