I am going to try to be thorough so I answer your question, number one cylinder is the one on the driver's side of the engine closest to the radiator. The Balancer has timing marks on it that will tell you when number one piston is at the top of it's stroke but each time it comes up it is either on the compression stroke or the exhaust stroke and number four which also will be at the top will be on the opposite stroke of number one. You can findout what stroke it is on by pulling the spark plug on number one and cover the hole with your finger until you feel compression, or remove the driver's side valve cover and watch the valves on number one and make sure they are both closed when the timing marks are lined up and that is where the spark should occur on number one spark plug. I hope that somewhere I got around to answering your question.

Is the keyway on a small block Chevy at 0 degrees?
This is a good question. Yes, the keyway, is accurate. What is not, is the balancer. After 74, the balancer keyway is offset, from the timing mark. Any harmonic balancer you use, look to see where the keyway is, compared to the hash mark on it. Make sure they line up.

Chevy 305 balancer does not line up with timing mark?
Some people mistakenly change the harmonic balancer or the timing cover, without matching it up. Some had a timing mark located at the top center of the timing cover, and some were off to the side (between 1 and 2 o'clock) If you have a mismatched balancer & timing cover, you will not be able to line up the marks. Sometimes the rubber goes bad, and the outer ring of the balancer slips... which would cause the timing mark to move.
