What causes the engine to go to TDC?
As the engine is rotated, the piston will force the dowel upward. When the end of the dowel is at its highest point, the engine is at TDC for the #1 cylinder.
Where is the 1 cylinder located at TDC?
It will appear in an opening in the bottom of the clutch housing near the starter. When the groove is centered in the opening the #1 cylinder is at TDC. Personally, I don’t care for this method because if the groove is not centered in the opening, the timing can be off ±1 tooth.
Where does the crankshaft go when setting to TDC?
So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
How to install a distributor and set initial timing?
Leave a little extra room with the spark plug wires to allow freedom of movement in the distributor. For Chevys, be careful to make sure 5 and 7 are installed correctly. If the wires are accidentally switched, the engine will not be happy. Before we try to start the engine, be sure the distributor is connected to switched power.

What makes a 4.3L GM distributor turn over?
With the socket wrench and give that belt a little more tension. Now, when you turn all pulleys and the engine will turn over. spark plug hole on the #1 cylinder. As the engine turns, eventually cylinder. Then, the pressure will suddenly go away, which means the piston has reached TDC.
So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
How to determine TDC after bottom end rebuild?
2) look through the spark plug hole and eyeball it till the proper piston is nearly tdc (you may be off a few degrees but at this point some marking on the crank should be pointing up, typically a dot on the timing cog)
When to set engine to top dead center ( TDC )?
Procedure NOTE When setting the engine to TDC on the compression stroke for cylinder #1, you must realize that the crankshaft rotates twice for every single rotation of the camshaft. So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
When to set the engine to TDC on the exhaust stroke?
