1967 Eldorado Update
I didn't do much in the winter being busy with school and just to cold to work but in the last week I have gotten a lot accomplished. First thing is I discover why it wont start. No spark, tested to coil and found that it is bad. I have gotten a new coil that I will put on tomorrow. I believe that the original failed because of age and a bad ground to the distributor. I found that the car does have ALC just not hooked up to the compressor but with a manual air filler behind the license plate. The final and most important thing is that I finally did a compression test today. I only did a dry test and was actually surprised by the results.
I triple checked every cylinder and found that they had way better compression than I thought.
Also when cranking the fuel pump started pumping. I was expecting nasty black floaty stuff but what came out was just some nice clean older gas. Not the best gas but good enough that I'm going to use it in the lawn mower.
I plan to have it running tomorrow. Ill make sure to have a video for that.

That engine should have more like 160-175 lbs. After it's running, check it hot w/the carb wide open.

Let me clarify so nothing terrible happens. After the engine is running & hot, shut it off, unplug the coil, open the carb wide & check it.

Thanks for the advise guys. I put a teaspoon of trany fluid in the cylinders to soak. I used trany fluid because of the high detergents to remove any dirt and carbon from the rings. I will remove as much of that oil as I can tonight if it hasn't all leaked past the rings.
Like I said that was a dry compression test with absolutely no oil up in the cylinders and rings. Those readings are a little low and scattered but I plan on a full rebuild at some point but for now I just want it to run.
Should I also do a leak down test or is the compression test enough?

She's alive. Got a new coil sprayed a little starter fluid in it and with the flick of the key it was running. Sorry I didn't video it as I was to excited to get it running. Sounded great.
The power steering work great as did the power brakes. What I was most impressed by was the vacuum locks work and hold their vacuum.
However all great things must come to an end. I was curious how close the timing was and when hooking up my light to the battery I heard some strange noise and by moving the main wiring harness I could repeat. Disconnected the battery followed the wires and sure enough the main cable going the the starter was laying against the exhaust manifold.
The alternator and all wiring in that area have been replaced by a person that should have nothing to do with cars. Any idea how the main power cable to the starter is supposed to be routed?
