I wonder if you connected the wires that feed the distributor? There is the harness and the 4 wires on the drivers side for power to the coil.

pull the coil, and make sure "button" that transfers the spark from the coil to the rotor is sitting UNDER the rubber insulating disk.
many people mistakenly install the insulator first, then drop the button in on top of it..
this creates a gap between the button, and the rotor.

make certain the button goes into the cap first, then the insulator disk goes over the button, with the spring going through it.

you would be amazed at how many times i`ve seen these installed improperly...

Haha ha ! Big Lee
I just did the same on my vette.
Thing is I overhauled the engine , put everything right , down to the last wire and vacuum line . started up good . Decided to change cap , rotor and coil , which was strangely behaving , wires too. You know , to make it safe , and it did not really slide . Lack of power . It was the center contact and ignition timing .
BTW , you have to turn off ECU when setting the timing That I learned too

You might want to watch out for the ignition module. Those things like to fail when a new coil is installed. I always replace the coil and module as a set.
