did you filp the distrib and give it a try?
this happened to me, thought everything was correct but I was one cylinder (or more) off....make sure the spark is happening at TDC on #1 compression.....and check distributor rotation <---ME duh

Take out #1 plug (dr front) & bump starter relay till you feel compression building on your thumb then w a 1&1/4" socket/short extension/breaker bar continue to turn it CW by hand till the marks are at 10BTDC. Turn dist housing till the magnet is dead even with the nearest tooth that puts the rotor under or very near under the cap terminal with #1 plug wire on it. Check that the wires are routed correctly CCW from that point (1)-8-4-3-6-5-7-2. With hundreds of dollars in a new build after all that cranking I would definitely spend the minor amt of time /expense to pull the intake & regoop the lobes/lifter bottoms. Removing and replacing the rocker arm assy's will not change the valve lash (solids). Read "breakin secrets" at www.mototuneusa.com (5 minute read). High zinc oil/no thermostat/fan in front of rad/several helpers to check for leaks/add trans fluid/time dist when it fires (36 w vac adv plugged & hit 36 then plug hose in)/charged battery. Any probs cut it clean/immediately then fix the prob & restart. Ahead of time I would plug in a spare dist & twirl it by hand to confirm you have spark. 4 or 5 squirts of the AP into carb/ choke activated if needed depending on ambient temp. #1 want it to start ASAP as soon as you start cranking

seperate the 2 wire pull apart connector for the dist pickup and key on, Morse Code tap the male end of the eng half of the harness to ground & see if the center coil secondary wire (dist end) held 1/4" from a ground sparks & if so take off the yellow "sol" wire from the starter relay to disable the starter and have a helper hold the ign key to start & you repeat the test. If getting fire on both tests then all is good in the 'hood in ign1 (run) and ign2 (crank) except this bypassed & did not test the dist pickup so if good on the 2 Morse Code tests but no fire when cranking with the ign key, if you have a spare dizzy plug it in & twirl the shaft end by hand same deal key on/sec wire 1/4" from ground & if it now sparks in both ign1 and ign2 then the dist in the eng has a pickup prob (gap .008" w brass feeler gauge). If on the very 1st test it only fires in ign1 or in ign2 then the dist/pickup is very likely good (do quick check the gap tho) and there's a prob in the ballast or the wiring and if it did not fire at all in the 1st test there's a prob in one of the components (ECU/ECU ground/coil/ballast/ign key/dist)or one of their supporting circuits' wiring.

with the key on i have 6V at the coil, if i unplug the ecu it has 12v at the coil with the key on. is that normal?
swap the ballast/ 6v isn't enough. what's the reading on the coil side of the ballast?

You might also double check that the rotor is pointing to the number one wire at TDC.
I couldn't figure mine out about a month ago either as I had good spark, fuel and no fire.
The intermediate shaft was one lousy tooth off and it wouldn't even kick after cranking multiple times. I figured it would've at least popped off a cylinder once in a while!

I recently fired up a rebuilt 440-6 on a test stand. Make sure the battery-starter connection is solid with a good ground. I had an issue with that. As others said, if you've done a lot of cranking, pull the intake and lube the cam. Check the intake runners, see if there is gas residue. May want to pull the timing chain cover and recheck cam/crank alignment. Be extra careful with the valley pan install. I had an intake leak that played havoc with startup and tuning. Re-verify CCW firing order.

Ha dthat happen to me.Seems I had a bad set of new plugs.Only 3 were firing.I pulled a used set from another 440 I had and it fired up.That and check compression on at least a few cylinders.That way you know what it has .Rocky
