Attention: TDR Forum Junkies 
My company has off the Friday before memorial day every year, so I used a couple hours out of that to do the timing advance on my VE. Jimmy, I know you were one of more than a few asking about it. Went pretty easy. I'd suggest dropping your vacuum pump/hydraulic pump assembly so you can get at that bottom bolt. It'll drive you crazy in a hurry to get at that guy. Even with a torch bent wrench, you can only turn it so far. If you torch bend a gear wrench, that would probably work, too. Me, I didnt wanna mess around so I dropped the vacuum pump. Pull the harness out of your oil pressure sender beforehand or you'll snap the thing off.
Don't forget the small screw in the bracket on the back of the pump. 10mm.
Once everything is loose, I found the best way to turn it was to stick the end of a prybar behind the max throttle screw and push (gently) against the pump top.
2 hours max if you got your head on straight.
Lastly, remember that even if you can get at the top screw (toward the motor) to loosen it, once you turn the pump you lose an awful lot of space in there, so have some way of getting at the thing at that point to tighten it back down.

. Even when I break out the dial indicator and have to find true TDC, it takes less than an hour. And that includes removing the fuel filter. I dont have a torch, but I got a Crapsman 1/2 crowsfoot.
