I would not turn on the start retard until you have your initial timing set to start the car. And as far as the start retard how does this work does it retard the timing 25 degrees 'Q' from initial timing, or does it put the timing at 25 degrees initial when you start the car? Sorry I have family over today so I cannot hover over the computer.

Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first.
Life was a little easier when I was just a wrench.

I'm not exactly sure how the MSD start retard works but...
To start the car you will have to advance and retard the timing until the motor starts.
Let’s say with the retard the car starts at 12 degrees.
Now that the car stated (above 600 rpm) the MSD will put the timing where it really is (+25 degrees for 'q')which is now 37 degrees initial plus you have the timing curve to content with. Well you don’t have time to set the timing because you have to break in the cam!
No, turn off the start retard.
Now that the motor will turn over, go to your first post and change the subject to
'No start... help' or 'No spark HELP!'

It should not be firing when the valve is opening so if it is pointing at the 6 while the intake is opening you are ok

Good, that's what I thought. I started second guessing myself, and was about to rotate it 180.

You know one thing I did not think of (since the battery is in the trunk) was possibility of voltage lost at the coil. Have everything connected like you were going to start it except the wire going to the coil '+' Hook this up to a voltmeter. Actually it can still be connected since the motor won't start.
What is the voltage when the motor is cranking?
If it drops below 9 volts while actually cranking then there is a good chance there is not enough voltage to power the MSD. I cannot remember the voltage required to power a MSD, but I think it was 8.7 and up?

Going to double check that I don't have the dist in 180 off. Right now, the dist is pointing to #6, and both valves on #1 are closed. Is this correct, or am I 180 off?
If it were me, I would recheck your 180 out theory at #1 not #6. Simply turn the engine by hand with spark plug removed from #1 until you feel air pushing out of the plug hole to verify that you are wired correctly.

Is the air gap in the distributor set properly? I went to fire up my new 440 a few weeks ago0 no spark. It ended up being the air gap was set at .065- 1/16" It should have been .008 max. when I set it correctly it started up immediately.
I sent the distributor to FBO to curve it and they also put in a new pickup coil and did not set the gap properly grrr...
I've thought about that, but haven't checked it yet. I will check it when I get home. Any tips on how to check it? Sitting here thinking about it, I don't see how you could tell what the gap is inside the cap.
