did the original poster even change or remove the timing gears/chain? looks like one could just get #1 cyl at tdc.. and jabb in the distributor..... should be good to go..
Remember, there are two TDC to account for. One where the ignition should spark, the other with the valve open. You must make sure you're at the right TDC to drop in the distributor. Just having the harmonic balancer mark lined up is making a 50/50 guess that you have it right. You must have the balancer mark lined up AND compression to assure you have it right.
