What Eddy said - and:

1) Since you've been moving the gear teeth around, before you do anything else, set the engine to TDC compression stroke and correctly align the distributor rotor.

2) Ground the distributor plug pin and set base timing to 5-7* BTDC..... no more, no less. 5* is plenty. You won't magically make any more power with >7* on a 3.0L and you may damage your engine.
