I know it's both exciting and frustrating to have a new car and not have it run. First thing you do is get a wiring diagram. Gotta know where everything goes in order to fix it, especially if it has been messed up. Start with the points, condenser, and rotor, spark plug wires and distributor cap and spark plugs. This gives a good way to know it isn't simply worn out parts and should run the best once the timing is set. Check all the wiring according to the wiring diagram and double check the wire going into the distributor housing itself, if it grounds in any way, it is not going to fire. Once the new parts and wiring is checked and verified, turn the key on and pull the points open and closed to see if there is spark. Use a screwdriver and look and listen for a spark. If you have spark there, she should fire as long as the firing order is correct and the timing is set, which you can not running check by rotating the engine by hand until the timing marks line up, then check the distributor that it had just fired to the number one or number six sparkplug wire (which is the sparkplug for 180 degrees opposite).  If this is all lined up, she will fire, adjust timing after that.
 
Welcome to the forum, we will get you going if you are good with following suggestions.

the cap and rotor look good and was replaced at one time befor it sat along with the plug wires.  what i was also woundering is there a way to go to electronic ignition on this 277 engine?  Thanks

NAPA should be able to get one I'd think, there was one on rt 3 just w
of Plattsburgh and one in Champlain iirc.  You should be able to
put a Pertronix unit in your dizzy, a good move.

Get spark from the coil first, then spark from the distributor to a plug wire, which will help narrow down the problem area. Rockauto.com has your ignition parts in stock, but better hurry, $2.50 for points is cheap, the other set is like $4.75, check them out, they are pretty reliable for things like this.

IMO it's nice to patronize a local store, if they can provide what's
needed, over an internet store, particularly if you want the small
local guy to stay in business. Most NAPA stores have high quality parts
and service, in my experience. Rock Auto could care about getting your
business. To use them to save $2 is fine, but when the local guy is no longer there you may miss him.

I have had a couple times that Rockauto was able to get a part to me the local places couldn't. When he said he couldn't find anything, Rockauto is the place I will go. You are right though, NAPA can usually get things for you.

I am sure the Pertronics should work, but for now and at this time, you should ensure you have power to the distributor and if everything there works, the swap would be much easier. Would hate for you to swap the Pertronics but find out something else is wrong to start with, putting you right where you are right now, only frustrated all that much more because she won't spark.
 
Go get yourself a used small block 318/273/360 distributor and do a little checking here. Measure from the underside of the lip that stops at the block to the gear and I bet it is the same length. Essentially the 277, being an A block, which was a predecessor to the LA block, if not mistaken, used the same distributor dimensions. It may be cast iron or something like that, but it should be the same distributor. It is a simple check.

Hey Mike, for used stuff, you know all about Rustic Auto Parts right? I used to love that place, lots of old cars in there!



I'm 99% sure the early A 277 dizzy will interchange with an LA one if you need one.

A Pertronix should work great, you'll get about double the spark. I put
one in an MG and will do so in the 354 Poly in my upcoming 58 Windsor.

I ordered a set of points at plattsburgh motor service today. but still going to try and go electronic. also i think the wiring is messed up  going to the coil/dist/resistor. So i need to fig that out

Then start with a wiring diagram, should be able to find something online for free to start with, then get yourself a factory shop manual, remakes are running $35-50, they are their weight in gold, and the cover everything under the sun, chrome clips, body panels, interior, electrical, everything.
 
Do you have an LA distributor laying around to verify they are the same dimensions? Agree with the 99percent same, but make sure it is wired as necessary, something we can help with.

i got a wiring diagram but it shows  12v hot to + side of coil black wire from - side of coil to resistor then to the distributor. Does that sound right? I know alot off ppl run a hot jump wire from battery to + side of coil to see if they have swith problems.   I found the PERTRONIX IGNITOR ELECTRONIC IGNITION 1383 i called summit racing and they said it will work. so im going to order one new off ebay for $68.  so after i get it i wont have to run the resistor/condensor?

You keep the resistor,toss the condensor.
The resistor still works to filter out noise going to the radio,etc.

The capictor was for ignition noise on the old AM radios.  Those were the old steel core wires.   The invention of resistor wires did away with all that.

im going to reinstall my points gap them at? i think 17 then wire the black wire from the dist to the - side of coil then run a 12v wire from battery to a toggal switch then to a resistor then to the + side of coil. when i turn it over im going to have a friend turn on the switch.  Just so i can tell if im getting fire.

What is wrong with the factory wiring that you have to go around it?
