SBC Distributor install and Timing

OK, Im having and old guy moment. I did the TDC #1 and installed the distributor pointing at #1 but I cant advance the distributor base enough to get the timing correct. I'm sure I'm off 1 tooth but does the rotor need to go back (counter clock wise) or forward (clock wise) 1 tooth?

The important thing is for your rotor to be pointing to your number one plug. You probably are off a tooth but in theory you could put it anywhere that the rotor pointed to a contact in the cap as long as you wired number one cylinder from there.

I just read an article that states the rotor should be pointing at the 6:30 position for the old style (Non HEI) distributor. This is the first time Ive reinstalled a points distributor, Ive always used HEI's.

Is the article correct?

The rotor needs to point at the #1 plug wire....no matter where it is, forget the 6:30 location. Get the #1 piston up to TDC on the compression stroke with the timing mark "near" 0 on the tab. Then with the distributor pulled up off of the oil pump drive rotate it either way till the rotor is pointing at #1 plug wire. You'll probably half to stick a long screw driver down into the hole and move the oil pump drive around a little so your dist. fits down over it, this may take a few stabs. You should then be close enough to fire it and reset the timing.

the rotor turns clock wise,turn it more to advance it.Its amazing how many cars Ive seen in the last year that still use points.
BTW,if the distributor doesnt drop down and you know you are in the correct place,just place your hand on the dist, body and have someone just bump the starter,it will drop when ready

After years of messing with and fighting oil pump shafts that moved when I pulled a Chevy distributor, I finally got smart years ago. I drop my oil pump priming tool into the hole and just turn it until it lines up and drop the distributor in.
All the hanging over the fender, or laying across the engine fighting and cussing with a long screwdriver is a pain, and the priming tool at under $20 is something everyone should have in their toolbox for Chevys. I cut a notch in the top of my tool with a file that lines up with the oil pump shaft, so I can look at the top and see which way the shaft is sitting when adjusting it.

That idea is no good at all. What about the glee you feel when you get it in on the first 3 tries. You have taken all the excitement out of laying across the fender, banging you head on the hood hinge trying to install a distributor that is on the wrong end of the engine. Surely no one will take this suggestion.
