#1 piston must be at TDC / Top Dead Center on the compression stroke.
Because the spark plug must fire when the piston is at top dead centre of a compression stroke. If the plug fires when the piston is at any other position then you get backfiring etc and no start. The correct firing order ensures the plugs fire at the right time.
18436572 The #1 cylinder piston must be up on the compression stroke when the rotor button is pointing to #1 plug wire on the distributer cap. The firing order is counter clockwise around the cap.
== == The firing order for the Chevrolet V-8 is 18436572. To change the firing order you must change the cam shaft. For example the # 1 cylinder firing can be changed with the #6 cylinder firing as long as the camshaft has be made to open and closed the valves at the proper time with each perspective cylinder. That doesn't mean you can simply grind a cam to change any cylinder firing as each piston has to be at TDC at the time when the valves are both closed for compression and consequent firing of the gases. Good luck. try 18436572
on 68-74 340 engines, the #1 firing order starts at drivers side, front of engine is #1 spark plug. Rotor in distributor cap, must point in that direction and piston in that cylinder should be at top of stroke. Align distributor cap wiring #1 where rotor is pointing to. Then follow firing order clockwise at top of cap. Rear of engine 8-7 6-5 4-3 2-1 Front of engine
the firing order is that you must shoot every pakki or Niger that walks past in the street (PS headshots only) rock out with your nob out ;) peace!!
most straight six engines have the firing order 1-5-3-6-2-4 this must be a big vauxhall for the time
The piston crown refers to the top of the piston. A piston can generally be divided into two sections (though the piston is a single piece). The lower part of the piston is called the skirt. The upper part, including the top of the piston that faces the valves and must handle the combustion of the fuel-air mixture, is called the crown. The piston crown must have the mechanical strength to withstand the forces of combistion, and must be made of materials that will withstand the heat of combistion. All this must come in a package that has limited thermal expansion so that the tolerances within the engine are tighter and performance is maximized.
I must assume you are asking about a 460 Ford V8, as you did not list make and model. Firing order of a 460 (7.5L) Ford is 1-5-4-2-6-3-7-8
If there is oil getting to the top of the piston and burning then you have a blown head gasket or the piston rings are worn or broken. Engine must be disassembled.
Yes!
Yes, that is correct.
AnswerThe firing order of the early 351W engine is different from the late 351W engines. The early 351W�s firing order is 1-3-7-2-6-5-4-8, while the smaller Windsor engine�s firing order is 1-5-4-2-6-3-7-8. What makes this interesting is that 289/302 cams are completely interchangeable with 351W cams, providing you match the firing order to the camshaft. If a 289/302 cam is used in a 351W engine, the firing order must be changed to the 302 sequence 1-5-4-2-6-3-7-8 by moving the wires on the distributor cap. The same procedure is used if a 351W cam is used in a 289/302W engine where the firing order in the distributor cap must match the camshaft. Not only is the firing order different on the 302- and 351W engines, but Ford also numbers its cylinders differently than GM engines. On the Ford it is 1,2,3,4 on the passenger side starting at front of engine, and 5,6,7,8 on the drivers side.I don't know who gave that "answer", but they must be Chevy people!! The 351Modified is NOT a WINDSOR engine!! It is derived from the 351CLEVELAND and it and its big brother the 400 share nothing with the little Windsor. The firing order for the 351/400M engines is 1-3-7-2-6-5-4-8. All the blah blah about 289 cams etc. is totally irrelevant to the question!!
