In the first model year of the Ford Mustang : The 170 cubic inch inline 6 cylinder is : ( point gap is .024 to .026 inch ) ( ignition timing is 6 * BTDC for the manual transmission and 12 * for the automatic transmission ) Also , the point dwell is 35 to 38 at idle
point gap 1978m ford
That truck should have electronic ignition, no points.
According to www . motorcraft . com ( no spaces ) unless the engine compartment decal shows different The point gap is .027 inch The point dwell is 35 to 40 and The ignition timing is 6 degrees BTDC for 200 cubic inch ( 3.3 liter ) straight 6 cylinder engine
Combustion lag refers to the time between spark(ignition) and the highest combustion pressure in an engine. Ignition timing refers to how many degrees before top dead center(top dead center compression in 4 strokes) the crankshaft rotation is during ignition. These two are connected by timing your ignition on point with combustion lag characteristics to tune ignition timing and gain max volumetric efficiency out of an engine. Timing advances (ignites farther from tdc) as rpm's increase.

After finding top dead center by turning engine over till compression on #1 cylinder and setting distibutor with rotor at #1 cylinder . engine was ready to be turned over . engine started now at this point is it necessary to remove a wire for crank sensor or ignition system to set the timing w a light.

Ignition timing is setting the point at which the sparkplug fires relative to where the piston is in the cylinder. The highest point the piston can go is called top dead center, or TDC. Timing is set for a number of degrees of crankshaft rotation BEFORE TDC; the number of degrees is determined by the factory, and since it's setting the plug to fire before TDC, it's called the "timing advance". If you set the timing to be closer to TDC than the factory setting, you're reducing the advance, or "retarding" the ignition timing. If you set it to be farther from TDC, you're "advancing" the timing. Changing the timing can dramatically change a motor's power and efficiency. The reason you set the timing before TDC is that you want the exploding gas to be compressed by the upward-moving piston and force the piston back down, generating power. If you retarded the ignition so far that the plug fired after TDC, the piston would already be moving down when the gas exploded and you'd waste most of the energy from the explosion.
28-32 degrees
Should be 28-32
base timing should be set through the distributor with a timing light. hook up one terminal of timing light to #1 cylinder's spark plug wire and other terminal to negative battery terminal. point light at crank pulley and adjust timing by un bolting the distributor and turning it slowly until the mark from the timing light on the block correlates to 16 degrees BTDC. any other electronic ignition timing on a custom tuned vehicle should be altered via tuning software and laptop by a competent high performance tuner.
