I verified spark at the plugs.
timing. Marks @ 10BTDC #1 compression, reluctor blade lined up w magnet slot, #1 plug wire where the rotor is and if it's off and you dont want to relocate your plug wires, pull the dist & reclock the inter shaft. EDIT Saw that you have new cam/ lifters, I'd definitely take off the rocker arm assys/pushrods/lifters and regoop the lobes/lifter bottoms

How tight was the cam bolt? If it loosened up the valves won't operate. Does the distributor spin when you crank it over?

Cam bolt was torqued to spec. verified valve action prior to bolting everything up. Distributor spins as expected with cap off.... even if I was 180 out, it would backfire like crazy out the carb..been there..done that...and did not enjoy any part of it..

David, check your E-mail.
Here is what I would do: pull #1 spark plug crank engine till you get cylinder pressure check damper timming (should be close to tdc) Make sure dist rotor is pointing at #1 plug wire on cap. (not 180 out) crank engine so timming marks are about 10 degrees BTDC. align the dist trigger with the pickup, this should set initial timing close to 10 BTDC. Put dist cap back on and double check fire order, reminder - Big Blocks are reverse rotation on the dist. check for spark at plug end (are the spark plug wires good?) add priming fuel and try to start engine. If it is really having issues starting/running then pull the drivers side valve cover, crank the engine to TDC of cam overlap and check that both the intake and exhaust are both slightly open to verify cam installation is at least close? if it checks out good, check compression or do a leakdown test. What was the new cam? could it have caused bent pushrods or valves?
On the Neutral saftey switch, it just allow you to crank the engine, so if the starter works, it is fine.
If the engine will fire when cranking, but dies when releasing the key, the ballast resistor is bad.

I might try grounding out the neutral safety switch as a test. Just run a jumper from the starter relay prong to somewhere on the body. I had ther same problem on initial fire up of my Challenger and had a brand new safety switch. Threw me for a loop since my switch and wiring was new... Also, the dizzy may be out 180. Been there, too...

air fuel spark if one is mising you get nothing. The N/S switch is a 3 prong plug that is mounted on the drivers side of the rans. Check it. Then do as above, make sure you have it at TDC, mark where #1 is. DO NOT USE the #1 on the cap. Start your firing order there. Prime the carb, a holley is easy fill it up thru the vent, work the throttle until you see it squirt gas. If yo installed a new T-Chain and gears maybe you are off a tooth or 2. To check for spark pull a plug hold the plug wire and pump the swtich...hahahha no don't do that stick the plug back in the wire and ground it to your engine, then bump it a few times. Dim the lights if you can. I'd check for spark at the coil 1st, pull the coil wire out of the distrib cap just enough to see it, bump it you should see the spark jump into the distrib.
