Ah, I'll bet that's your problem. You see, cam timing actually determines when each cylinder is at the firing position (TDC ignition) and it's possible that you've set the timing correctly, but one revolution away from where it used to be. That is, when cylinder 1 used to be at TDC ignition, now cylinder 4 is. So, to correct this you need to remove the distributor and put it back in rotated 180 degrees.

Do this:

1. Pull the valve covers for the left bank.

2. Rotate the engine to the Z1 mark and check to see if both rockers on cylinder 1 have clearance (valves not being depressed at all). If not, turn the engine over one full revolution to Z1 again. Now both rockers should have clearance.

3. Pull the distributor cap off and look at the rotor. If the tip of the rotor isn't pointing towards the electrode for cylinder 1 (I think there's a rough timing mark on the distributor body, too), then you need to remove the distributor, rotate it until it does, and reinstall it.

4. At that point, you should have things close enough for the engine to run. Then you need to set the ignition timing properly with a timing light.

I know this is frustrating for you, but you really need a basic understanding of a four-stroke internal combustion engine to tackle this kind of project, and it's obvious you don't have that. While I think books like 101 Projects and the like are a great resource, they do some owners disservice by encouraging them to tackle work they really aren't ready to do themselves. You've only owned this car for a couple of months and already you're trying to rebuild the engine, and in a very shortcut kind of way.

Good luck.
