Make sure your plug wires are on correctly. Maybe the wires are off by one on the cap and that's why you can see spark but not when its the right time to fire that cylinder.
Maybe your Carburetor is gummed up? How long was it sitting before you swapped it on to this motor? Are the bowls filling up? Can you smell fuel?

No backfires, no sputtering, nothing.
Even with the distributor "off" or wired clockwise you'll occasionally get a spark that "hits" on a cylinder.
It's got to be an ignition problem!

1 Did you wire the distributor COUNTER-CLOCKWISE? 2 Are you for sure using a BB distributor? Lining up the dots when doing a timing chain doesn't get it! You really should degree in the cam. My MP .528 Mechanical and Cloyes Tru-roller combo was 8* retarded when installed in the "straight up" position!

When you put the marks on TDC how did you line up the reluctor/magnet & was the rotor under (or very close to) the #1 wire cap terminal. Yes it's gotta be something simple we have missed

Electronic distributor?
What's your reluctor gap?
Should be .008-.011 IIRC with a brass feeler gauge.

hi make it easy ! remove the dist from engine and keep it pluged to the wire harness ! turn on key spin dist shaft to verify you are getting spark ! you should easily hear spark current making a sharp ticking sound . no spark , go back and clean grounds and try agin !

I don't claim to be an expert on neutral safety switches..in fact...I don't really now squat about them. When you turn the engine over, doesn't the neutral safety preclude the plugs from firing? If mine fire in sequence, that would indicate the ability for the motor to ignite the fuel? So, as a dummy..where does the neutral safety switch prevent the ignition system from functioning? Yeah, off topic, but still a good subject to learn from... and I am out of gas in my spare can cuz the kids put it in the four wheelers today
The neutral safety switch prevents the starter from turning over the engine. If the engine turns over the switch is engaged.

So here is where I am. I pulled all wires, put number 1 at TDC on compression stroke. Relaced it all up..primed carb with gas. I get some popping out the exhaust and through carb, some smoke drifting out of carb...but no signs of firing off? Please tell me I did not hose up the timing chain install! I lined up cam and timing mark. Used a standard NAPA brand timing set. I have good spark, plugs are good, wires are good..the shortblock I built had piston, rings, crank..basic shortblock already assembled. What gives? Compression feels strong. I will get a compression tester tomorrow to double check it. This is very frustrating.... gotta be something I am missing here..
I'm guessing you tried moving the distrib around some? sounds like you are getting fire and gas it's just not in "time" yet.

Mopar V8s are not interference motors like the Jap scrap. They won't bend valves if the timing chain is off.
Oh yes they will. Seen lots of eye brows when timing chains went south.

I haven't seen a factory motor do it but yes if you have a built engine it's very possible.

a stock rebuild would not have any interference issues. He needs to get a buddy over and help him out. It's hard to do all that junk by yourself.
