Chevy 5.3 Firing Order (Cylinder Numbers With Diagrams) [1]
There’s so much you need to know about the Chevy 5.3 firing order! What is the purpose of a firing order? Why is a firing order important? How do you determine a firing order?. For anyone who may be confused about the 5.3 ls firing order, this post is for you
In short, The firing order on a 5.3 ls engine is 1-8-7-2-6-5-4-3. This means, the spark plug at number one cylinder (1) fires first, then number eight (8), and so on.
The number one spark plug fires first, followed by the remaining spark plugs in their respective order. It is best to always check the owner’s manual for your vehicle to find out the specific firing order.
Chevy Firing Order [2]
The firing order of an engine is the sequence the spark plugs fire. On engines with a distributor, the firing order is determined by the routing of the spark plug wires from the distributor cap to the spark plugs in each cylinder
Depending on which way the distributor rotates (clockwise or counter-clockwise), the next plug wire in the cap would go to the next spark plug in the firing sequence for that engine.. On most Chevrolet engines the #1 cylinder is the first cylinder at the front of the engine on the driver side (left side) of a rear-wheel drive car or truck
The cylinders are numbered in a staggered sequence going from side-to-side, starting with the #1 cylinder going towards the back of the engine (see illustrations below). So on a V6 or V8 engine, one bank of cylinders would all be odd numbered (all the left cylinders on a rear-wheel drive V6 or V8 engine, or all of the front cylinders on a transverse mounted V6), and the ones on the opposite side would be all even numbered cylinders.
Firing order [3]
This article needs additional citations for verification. The firing order of an internal combustion engine is the sequence of ignition for the cylinders.
In a diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder. Four-stroke engines must also time the valve openings relative to the firing order, as the valves do not open and close on every stroke.
The numbering system for cylinders is generally based on the cylinder numbers increasing from the front to the rear of an engine (See engine orientation below).[1] However, there are differences between manufacturers in how this is applied; some commonly used systems are as listed below.. Cylinders numbered from front (#1 cylinder) to rear.

Is the driver side the odd bank and the passenger side the even bank?. And does the numbering start from back or front of engine.
Looked in the factory service manual and cold not find a thing on this. So, I would guess from this the drivers side would be odd bank, or would that make to much sense? Hopefully this helps!

This article needs additional citations for verification. |Predecessor||Chevrolet small-block engine (first and second generation)|
First introduced in 1997, the family is a continuation of the earlier Chevrolet small-block engine (first- and second-generations), of which over 100 million have been produced altogether,[5] and is also considered to be one of the most popular V8 engines ever.[6][7][8][9] Spanning three generations, a new, sixth generation is expected to enter production soon.[10][11] Various small-block V8s were and still are available as crate engines.[12][13]. The “LS” nomenclature originally came from the first engine of the Gen III engines, the LS1, which was fitted in the Chevrolet Corvette (C5).[14] The Regular Production Option (RPO) code of the engine, LS, has since been used to generally refer to all Gen III and Gen IV engines,[15] however, Gen V engines are generally referred to as “LT” small-blocks.[16][17] This can sometimes be misleading, as not all engine RPO codes in the three generations begin with LT or LS.[18] LS and LT engines have powered every single generation of the Corvette since the C5, with the exception of the Z06 variant of the eighth generation Corvette, which is powered by an unrelated small-block engine, the Chevrolet Gemini small-block engine.[19] Various other General Motors automobiles have been powered by LS- and LT-based engines, including trucks such as the Chevrolet Silverado, sports cars such as the Holden Commodore and SUVs such as the Cadillac Escalade.[1]
The brainchild of Chevrolet chief engineer Ed Cole, first generation of the Chevrolet small-block engine were first unveiled in the 1955 Chevrolet Corvette and Chevrolet Bel Air, both powered by the 265 cu in (4,343 cc) “Turbo-Fire”. The 265 Turbo-Fire distinguished itself from other engines of the era such as Cadillac’s 331 series of the late 1940s and early 1950s by reducing the size and weight of various components within the engine; a compact engine block combined with a light valvetrain gave the Turbo-Fire a 40 lb (18 kg) weight reduction compared to the inline-sixes that initially powered the first generation of the Corvette, alongside a significant horsepower increase of 25%
