Help With my crate 427 Engine Won't Start

I got the usual from the Ford performance dept… “never seen that problem in 20 years” I at least got a set of gaskets from them because it’s still under warranty.

At first, I thought the engine oil dye I used may have caused the oil color change but after letting some oil test samples set on my counter for a week, I can see some water separation at the top.

After taking my utmost time in changing out the gaskets and adjusting the rocker lash, and re assembling I cannot get this thing to start, it does the typical backfire and flame through the carburetor (timing was not off 180). I quadrupole checked TDC and alignment on #1 cylinder with the rotor cap, plugs are wet, and all valves are opening and closing, plus checked for spark, everything good.

I talked to an engine builder buddy from work and we both are now thinking it might be the Progression electronic distributor/ignition as a possible cause. I talked to them, but they don’t feel its their problem, but I can send it back for them to check.

This just doesn’t make sense. I dressed the engine up from the crate long block and it started right up, and I ran it many times for about 2 months. I was so impressed it would start with 2 pumps within 1 crank, better than fuel injection, so I thought.

Wires were installed as a unit with the cap when assembling so it’s not a wire mix up problem. I’m thinking of sending the ignition/dist. back to see if they can check it, and possibly installing a mechanical type for trouble shooting or eliminating this variable.
Not sure what else to try.

This is the first clue. Electronic curves are calculated after a reference angle. Each spark event is a "retard", because of the module calculation, but it appears as an advance curve.
The reference angle is typically 50-70 degrees BTDC.
Are you sure you are following your distributor alignment procedure correctly?
