What is the firing order for the bronco 2 1986and where is number 1 on the distributor and which piston is number 1 on the block

with the distributor at the rear of the block and looking at the front of the engine then pistons 1-3-5-7 are on your right hand with no 1 being the front piston. on your left will be 2-4-6-8 with no2 being the front piston. from the front and looking down on top of the distributor cap no 1 HT lead will be positioned at the 11 oclock position ( 12 oclock will be dead in line to the front of the engine). The rotor turns in an anti-clock wise direction Looking from the top . The firing order is 18436572 when installing the distributor ensure that the no1 piston is at TDC compression stroke

Firing Order: 1-8-4-3-6-5-7-2. You should be able to find the order listed on the intake, just below the front of the carb.

Piston Numbering From Radiator To The Firewall:
Driverside: 1,3,5,7 (1 is closest to the radiator)
Passenger: 2,4,6,8 (2 is closest to the radiator)

Trace your #1 piston spark plug wire from the engine to the distributor. Firing order on the distributor is clockwise from #1.

This method is good for the firing order on all chevy small block v8 engines from 265 cubic inches to 400 cubic inches. This would include 265, 283, 305, 327, 350, 400 cu. in. chevy small block v8 engines.

Let's cover some safety concerns first. If you try to troubleshoot a mixed up firing order with the engine running, you could be in for a serious shock,.. literally. You can do it, with certain precautions, but you really don't need to check the firing order with the engine running. You definitely don't want to try checking the firing order if you are wearing any kind of pacemaker or sensitive electromechanical prosthesis. The voltage coming out of the ignition coil is in the thousands. Common sense dictates that you wouldn't stick a knife in an electrical outlet, so you wouldn't want to take chances with being shocked by the electrical discharge from your classic chevy's ignition coil either. See the diagram:




The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.

On classic chevy small block engines that use ignition breaker points instead of electronic ignitions, the number one cylinder is the one immediately clockwise of the small metal sash cover on the distributor cap. The firing order starts here. There is no sash cover on the distributor cap for GM HEI electronic ignitions, and the firing order is the same, but starting at the 5:30 position.
The firing order makes sense if you know how the cylinders are numbered. The number one cylinder is the front most on the drivers side and 2 being the front most on the passenger side. From front to back, the cylinders are odd numbered on the drivers side, and even numbered on the passenger side.

firing order piston number (1-2-4-3) clockwise at distributor
at the engine from right 1st piston =piston number one
the engine from right second piston =piston number two
the engine from right 3rd =piston number three
the engine from right 4 =piston number four
