Angry Rebuild screeches to a halt--WTF!!! Free beer!

Quick background. Old 4.6 had a porous block. Swapped to another used, pressure tested block. Same crank (ground a second time, .20/.20), new bearings, timing chain, same old everything else. Built it in the garage, just dropped it and tranny/transfer back into the truck and assembled 90% of it. Went to put on the pulleys and belts and the first thing I noticed is that the BELT TENSIONER CAN'T ALIGN WITH THE CRANKSHAFT PULLEY--it can't come out far enough. That can't be right. Water pump pulley doesn't align with the crankshaft pulley, either. Aren't the timing marks directly under the timing indicator that bolts to the front? Mine isn't--the indicator barely reaches the flat area and doesn't come close to the marks. The Alternator, however, has it's pulley aligned with the crankshaft pulley which leads me believe that the front cover doesn't stick out far enough which doesn't make sense.

The front of the crankshaft is only slightly recessed from the flange on the pulley (enough to cause tension/friction when you put on the crankshaft bolt)--I have a spacer on the crankshaft since I am using a 4.6 crankshaft but old style timing cover (distributor)--but I am reusing the same one.

I have no fucking clue what is going on. Yeah, I am tired, grouchy and pissed, but I still tried to figure this out and am stumped. I'm feeling a bit stressed right now--I know my wife and friends would like to see me more but I really don't function well when my D90 is sick and it is almost wheeling season. Help if you can--I am missing something and the first person to let me know what boneheaded mistake I am making I will send a selection of my absolute favorite IPA Beers to. I'm a hop head, for sure.

The only thing I can think of is that your either your crank key is keeping the spacer from dropping all the way in, thus causing your pulley(balancer) to not tighten all the way. so just to be sure or your oil pump shaft is preventing the distributor drive gear to slip onto the crank all the way.

1 slip distributor/oil pump drive gear on crank (hopeully as mentioned above you did not try to install the oil pump shaft as it may be preventing the drive gear from seating on the crank

2 put in spacer,
3 tighten down balancer

4 install pump gears and pack pack pack that mofo with grease so that it gets the oil pressure up quickly
5 install the distibutor drive gear.

I thought (from dim and distant memory) that the oil pump and distributor ran off of the cam shaft drive?
Either way I'd pull the front cover and check everything with a clear head, something isn't right and trying to force it will end in broken gear.
Try checking the pulley seats correctly on the crank without the front cover on, take some measurements to the pulleys from the front of the block then you can see if the alignment is right.
