Timing and Firing Orders

If your doing static timing ( #1 piston tdc compression stroke) then the rotor should be pointing at the #1 piston which is driver's side front. also to know that its close it should also be pointing at the coil. if it doesn't line up correctly then remove distributor and with a long handled flat tipped screw driver look into the distributor hole and turn the oil pump rod to line it close to the same direction as the rotors position.

Wow! That was probably the guy who wanted $38 to tell me a plug gap! There is a little more to it than that. If you have a small block that was built by Chevy, then you have one of those rare ones that the crankshaft turns twice, to once, of the camshaft. And, if your starting from scratch, a new motor, say, then you wont have anything to go by. Ok. Here it is, Ready? when number 1 piston is just before TDC, (top dead center), (number 1 cylinder is driver side, front,) the timing could be 180 degrees off. Since 1, and 6 oppose each other, look at the intake, and exhaust valves on number 6. The exh. should be just closing, and the intake will be just opening. This, my friend is called "overlap". 6 will have completed its exhaust stroke, and starting it's intake stroke, when 1 is firing. As far as where the rotor is pointing, is not important, as long as you make that number 1 cylinder. Then follow it with 8436572. Mystery solved. Drivers side from front is odd, ie.1 3 5 7, from front, and pass side from front, is 2 4 6 8. You can make number 1 anywhere you want, as long as the rotor is pointing to it @ TDC, while 6 is on overlap. Another trick, turn the dist. a touch counter clockwise from 1. With points, you want to reverse the dist until they are open. This will put a touch of advance into the timing making it easier to start. Remember, fire out of the carb, is too much advanced, turn the dist clockwise. Backfire out the exhaust, is too much retard, so turn it counter clockwise a touch. I like to move the dist. while someone is spinning the motor over. And do not make an idiot out of yourself, by using a screwdriver to turn the oil pump drive. Simply pit the dist in as far as you can, just counter clockwise of the number 1 post on cap. Have someone lightly tap starter over, while you hold dist down. As the cam comes around, it will turn the gear, (don't hold the rotor, hold the aluminum body), and the dist. will fall right into place. Remember when you decide where no. 1 will be, make sure you have enough room to adjust timing. The vacuum advance may hit intake runners. Also, you are better to set timing @ total, rather than initial. Initial makes it run, however, total is where the motor runs most of the time. Happy motoring.

1-2-3-4-5-6

The same as all other small block Chevy V8 engines 1-8-4-3-6-5-7-2

Rotor turns clockwise.

The firing order is 1-4-3-2. From looking at the motor, cylinder 1 is right rear, cylinder 2 is right front, cylinder 3 is left rear, and cylinder 4 is left front.

Check Lowes and Home Depot they normally carry the adaptors

The vehicle computer commands the ignition coil to fire the spark to the plug at a specific time. The crankshaft pulley has a mark located at tdc (top dead center) position of cylinder #1 only , so you must use the cyl. #1 plug wire in order to accurately view the mark on the crankshaft pulley and the block.

You should change spark plug wires because with time they'll become frail, the rubber will get hard and crack, creating a place for the current to escape leading to misfires, loss of power and other annoying problems.

if on a 98 f 150 v8 5.4 , if you put the 1st link on mark in stead of in center of 2 marks and the sproket looks at 12 and or 11 will it be out of timming

straight down from the front of the air filter. There are 2 coils mounted to the ignition control module. the firing order starting from the bottom of the coil packs is 1-4-2-3. Plug 1 is on the passanger side of the car.

1 - 3 - 7 - 2 - 6 - 5 - 4 - 8

The distributor rotor turns COUNTERCLOCKWISE

The marked # 1 position on the distributor cap faces to the rear and slightly towards the drivers side

The engine cylinders / spark plug locations are numbered :

4 - 8

3 - 7

2 - 6

if you mean the ingintion timing marks, they are on the crankshaft pully. Use a rag and some cleaner to see them clearly.

According to my Chilton book :

The distributor rotor turns CLOCKWISE

The firing order is ( 1 - 2 - 3 - 4 - 5 - 6 )

The engine cylinder locations are numbered :

5 - 6

3 - 4

1 - 2

And according to the picture , the # 1 position on the distributor cap faces towards the FRONT

You cannot adjust it and it is set by the computer in the car, it can vary by altitude, speed and accelleration.

There are two possible firing orders 1,2,4,3 and 1,3,4,2.
