The tach not moving generally indicates a bad crank position sensor.

I'd double check timing, and I've mentioned this before, make sure you have the cams in the correct place. The exhaust cam is furthest forward in the engine, and it has a notch on then end where in past designs drove the distributor. My machinist swapped these once on me and we wasted a bunch of time trying to figure it out after a rebuild.

Check for fuel, do the plugs seen wet? If you can't hear the pump I'd pull a plug and look. You can also check for spark by setting the di up with plugs in and grounded with a wire.
