This is a little over kill, but it will be accurate.
Go to your parts store and buy timing tape for your balancer.
Now borrow a piston stop from someone or buy one.
Pull a spark plug and insert piston stop. Pull the piston stop back as far as you can and still make contact with the piston. You have now found top dead center. This may take several times of rocking back and forth on the crank and screwing the stop in and out. Get it to the farthest point out that you can turn the motor and have it touch the stop
Now place the timing tape on the balancer, lining 0 on the timing tab up with 0 on the timing tape.
Now you can use your timing lite to its complete effectiveness.
If its a typical sbc...34 degrees total timing should be a good starting point.
