A 289 Ford small-block V8 in a 1965 Ford Mustang. The 289 cu in (4.7 L) V8 was introduced in April 1963, carrying the Challenger name over from the 260 [3] and replacing it as the base V8 for full-sized Fords. Bore was expanded to 4.00 in (101.6 mm), becoming the standard for most small block Ford engines. Stroke remained at 2.87 inches.
As expected, the actual design of the crank shaft also affects the firing order. These numberings are IRRELEVANT without a list of the numbering pattern of the cylinders For example, the GM LS1 example has the exact same firing pattern as all Ford V8s (post 1988), the only thing that differs, is the cylinder numbering.
For this inline-4 engine, 1-3-4-2 could be a valid firing order. The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. In a diesel engine, the firing order corresponds to ...
Thus talking about a big versus small block Ford is something of a misnomer as there were actually three different block sizes from 1958 through 1976. Buick had only one block size, the Nailhead (4.75"), until the introduction of its small block in 1961 (4.24"). This engine was used on other makes, in particular Oldsmobile and Pontiac.
Many people call almost all small block Ford engines, following the Y block series, "Windsor" engines. This is incorrect however. The one and only "Windsor" engine is the 351W engine. The reason for this is all of the other small block ford engines were built in the Cleveland pland, while the 351W was built in the Windsor plant.
Note: this is commonly called the Ford Small-block V8 pattern, though it is used in some "big block"-sized V8's as well as some V6's and I6's. 200 I6 1978-1983 only, partial (4 of 6 bolts) pattern. 250 I6 (except Australian 250/4.1) 255 V8; 289 V8 - (made after August 3, 1964) - had 6 bolts holding bellhousing to block; 302 Cleveland (Australia)

A big bang engine has an unconventional firing order designed so that some of the power strokes occur simultaneously or in close succession. This is achieved by changing the ignition timing, changing or re-timing the camshaft, and sometimes in combination with a change in crankpin angle. The goal is to change the power delivery characteristics ...
