You still have not said if you actually have spark at the plug. This should be first step.

73 Grandé H Code. Headman long tube headers, T-5 Transmission, 3.70 Traclok, Lowered 1" all around, Aussie 2v heads w/ 2.19 intake, 1.71 exhaust, screw in studs, full roller cam 608/612 lift 280/281 duration LSA 112, Quick Fuel 750 CFM double pumper, AirGap intake.

You can get a remote starter at any auto parts store. Generally about $15. I honestly can't imagine not having one when doing diagnostics. 

IMO, this is a decent flowchart for diagnosing a no-start condition.

Well, um, now it's first on the list.  Wanted to eliminate all the overlooked possibilities first, such as discovering that messed up rotor.

And one of those inline spark checking tools. Good for for finding a weak plug or wire, too.

You mention Pertronix in this post.  I lost a ton of time with mine passing all the 12v tests and my car not running.

Start with the trusty old point breaker system.  I finally did that and mine runs great.  I could not get the Pertronix to even start after a while due to all the variation in the timing on the mount plate.  I put the point breaker plate back in with new points and condensor and it has not missed a start or a beat while running.

Pertronix was returned for refund.( look at my post on Countdown to Start day.)

This is why you should run a new, dedicated 12V power source to the pertronix. I do this. Never a problem. Installed lots of them. My racecar has had the same pertronix in for 17 years. Never touched it.

Use Hemikiller's flowchart, it's a good one. Start at the top and work your way through it. Do not assume that one of the items is good and you can skip it, that will be the one that is causing the problem. Do not skip any steps, even though you are certain it is good.

Unless you are an accomplished mechanic, with all the necessary diagnostic tools and experience, never add goodies like an electronic ignition or fuel injection before the first startup and all of the initial bugs are worked out. Start it with the original points and a good carburetor, get it running good, then add goodies one at a time.

I prime the carburetor by adding a couple of ounces of gas into the fuel bowls, through the vent tubes, before the first startup. That way if it doesn't start I don't have to wonder if it's a fuel delivery problem. Like David said, pouring gas into the carburetor while cranking it is a recipe for disaster. Do you watch any of the car build shows on TV? Half of the time the engine doesn't start on first try.
