My ‘77 264 B27F isn’t starting after replacing the oil. The back story here is that the car was stored for about 6 years. When I managed to get the engine running, it ran extremely rough and produced a ton of white/blue smoke. I corrected this issue by freeing the fuel distributor piston. Once the piston was free, the engine ran smooth. I drove the car up and down the street, though I noticed the engine had no power. I drained the oil, which was tainted with gasoline. (Gas got into the crankcase when it was running super-rich) I replaced the oil-pan gasket, let the rpv dry overnight and put in 6.5 quarts of Mobil-1 15-W50.

Now the car won’t start. By changing the oil, I assume that changed is the pressure in the crankcase and this is somehow contributing to the issue.

Here’s what I know:
The gasoline is fresh.
I’m getting good compression. (130PSI per cylinder)
I’m getting a spark to each plug. 
The plug wires are on in the correct order.

When I turn it over, and head back to the tailpipe, I see a small amount of smoke slowly wafting out. I’m thinking possibly that the car is running too lean. I note that when I loosen one or more of the fuel line bolts on the fuel distributor, and crank the starter, fuel does not seep out of the line, but if I press slightly on the throttle body, fuel does seep out. This makes me think that fuel is not being delivered to the cylinders when I’m cranking it...

Oh, and it should be noted that I sprayed carb-cleaner into the throttle-body and the engine didn’t react as I expected it would, in that I expected it to try to start. I also loosened the distributor bolt and changed the timing, hoping to make a difference, but no luck...

Could this be a vacuum issue? On most older engines I’ve dealt with, a loose or missing vacuum line wouldn’t prevent the engine from starting. Can a vacuum issue prevent fuel from being delivered?

Thanks for the help!
