Answers :

Remove #1 spark plug put papper towel to cover hole only. You can cover it with your finger also. Turn the motor by bumping the motor over .When you fill presure or papper pop out.That is the compressing stork.Then look at timing mark on crank and turn to zero.You are at TDC.Put crank and cam marks lines on grear together with chain on.This will start the car then you will need to time it 4 to 6 advance with timing light.
I used to have one of these...there are 2 top dead centre positions you have to watch for. Top Dead Centre "Compression" and Top Dead Centre "Exhaust".

With the distributor cap on, you will know where number 1 is on the distributer, remove the distributor cap and then turn the motor using the crank...keep turning until you see the rotor pointing to number 1. If the number 1 piston is at TDC then you are good to go with it being at TDC Compression- rotor at 1.
If your rotor is at number 1 but your number 1 piston is down then you need to remove the distributor from the rotor 180 degrees then slide the distributor back into the block carefully...remembering to be careful because your oil pump is run by a shaft which snaps onto the bottom of the distributor.
