Timing help, going nuts

[bigchevytruckdriver2]

Putting the distributor back in my truck and have put it in wrong 3 times. Driving me nuts. The last time I had the wife bump it over with my finger in the number 1 hole until it started to pressurize. Then manually brought it around until the timing mark was on 0* btdc... or so I assumed. When I went to stab the distributor to line it up with the number one contact it definitely wasn't right vacuum advance tight against the firewall and the connection for the battery/ tach connections is pointing at the carb, seemingly about 90* out. Am I missing something, doing something wrong, please help. Not new to this either so that makes it more irritating. I know for sure the mechanical timing is correct as the truck was running before just not to well and the engine is basically new.

sounds like your trying to use the existing plug wiring on the cap..

get to TDC.... you want the rotor to point at #1 cylinder.. if it doesn't drop all the way, you need to turn the oil pump drive with a long flatblade till it drops and points at #1.... turn dizzy to whereever you want the vac and wiring.. than lace the cap with the corrosponding tower as #1 now to where the rotor is pointing...

Like Ryoken said. You are having issues getting the oil pump drive correctly aligned.

Set the engine at TDC #1. Climb up onto the truck look into the distributor drive. Align the dist to point TD 1. Then turn the oil pump drive to about 5 degrees back from what looks aligned. It should drop in then. Be patient. 18436572.
