OK, it's possible that the balancer has spun and giving you false ignition timing readings. Now that you know the valve timing is correct, remove the cam sprocket cover on the driver side, turn the engine to align the mark on the cam sprocket with the mark on the rear cam cover. Look at the crankshaft balancer timing mark.... if it's not on zero you have a spun balancer hub and it should be replaced.

As for the ignition wires, did you notice that the cap is marked? As you look at the engine from the front, the 3 wires on the towers to the passenger side go to cylinders 1-3-5 and the 3 on the driver side go to cylinders 2-4-6.... like this:

Frank, Nice to meet you,

Once I got her back together I did exactly as you suggested and checked TDC vs Cam sprocket alignment. She's right there at zero.

Now about the spark plug wires, I learned that lesson first thing when we got the engine back together after the rebuild. I set the distributor just like I do on my jeeps, rotor facing #1 tower. Boy that stumped me for a few minutes what with her coughing and bucking and all. After fiddleing with it for a while I turned the cap upside down and found that the japs played a trick and didn't put the contacts under the towers. Had a good laugh about that with my son! <img src="/forums/images/graemlins/lol.gif" alt="" /> Once we got her corrected she fired up and ran. I do like how they keep the wires running straight tho.

Do you know what vacuum and fuel pressure yours runs at? Also if you have ever checked your stall speed? The fsm says 2100 - 2400 rpm ( I'm a long way from that @ 1600)

By the way, That sure is a purty engine <img src="/forums/images/graemlins/cheers.gif" alt="" />
