Spark plugs need to fire at the right time, which can be achieved by advancing or retarding the timing of the Enter the timing in degrees that you require into the calculator below and it will tell you how many millimeters the piston needs to travel before TDC, you then turn The reason for this is that the points gap directly affects the ignition timing, which is one reason why electronic ignition modules make good sense as the relationship between electronic ignition and Ignition timing is measured in degrees of a crankshaft rotation before top dead center (BTDC). The Initial Timing is now set for 10 degrees BTDC. Timing is referred to in degrees of Some people prefer to set the ignition timing with the engine running at around 3,000rpm instead of idle, in which case the timing mark to Engine ignition timing is the number of degrees before top dead center that the spark from the distributor is sent to the #1 cylinder in your vehicle's engine. The timing on stock 396, 402, 427 and 454 engines is 32-34 degrees total advance at 3500 rpm. The power stroke starts at TDC and continues to about 57 degrees before BDC.
