Are you sure it's in gear? Are the pistons moving, or is the rear wheel easy to turn by hand?

I assume (and hope) you do not have the pushrods in at this time.
It is always a good idea to have the timing cover installed before you go rotating the engine.
Not all the screws in but rather put the cover on the dowels and attach with 2 screws.
The timing cover is afterall the outer support for the cams.
So at this point I do not know what to say but I have a question for you: Did you time the oil pump breather tower?
That needs to be done when you have removed the pump.

What gear do you have it in?
In first you are going to have a really hard time turning it.
Put it in fourth gear.

(1) Will the wheel rotate backward?
(2) Put it in neutral and see if the wheel now spins freely. If it does, then something in the engine is jammed.
If it does not rotate in neutral then look at the sprockets where the chain goes and see if there is not a nut or bolt causing the binding.

Spins free in neutral, the tire will go backwards but is tough, no jams
