Give my way a try before you get drastic.  Take a look at the 
procedure given here:

http://www.custompistols.com/cars/articles/ignition_timing.htm

Note this part:

So, the first step in any static timing operation is to set the 
engine to the required number of degrees before top dead center on 
the compression stroke. At this time, both the intake and exhaust 
valves should be closed and the rocker arms loose. (Removing the 
rocker arm cover and watching the intake valve, the second valve from 
the front open and close as you rotate the engine over either by 
using a 1 5/16" wrench or socket on the crankshaft pulley or pushing 
the car with the engine in gear is not a bad idea the first time you 
do this to make sure you are actually on the compression stroke. If 
you push the car, take it out of gear and set the handbrake before 
proceeding to ensure the engine can not move off the proper timing 
mark.) The brass tip of the rotor should be pointing towards the 
number one terminal of the distributor cap at this point. If it is 
pointing towards the number four cylinder nipple, your timing is "180 
out" or you are on the exhaust stroke of number one cylinder, not the 
compression stroke.
