Pontiac 6.0L (364 cu in) firing order — diagram & guide
Mastering power dynamics with the Pontiac 6.0L firing order.
Before the end of its life cycle as a brand, Pontiac left us with some all-time classic sportscars. Some of their most iconic models were powered by the 6.0-liter V8 and if you happen to own one of these, now is the time to start paying extra attention to maintenance.
If your Pontiac gives out the signs of misfires or spark plug replacements needed, this guide on the Pontiac 6.0L (364 cu in) firing order will help you solve those. We’ll give you a tour through the engine’s firing order along with the cylinder configuration to help you keep the common issues at bay.
Pontiac 6.0L firing order
Before we get into the details, the most important thing is that the Pontiac 6.0L firing order is 1-8-7-2-6-5-4-3. There are two base 6.0-liter engines used in Pontiac cars – the L76 small-block V8 and the LS2 engine. Luckily, both these engines used the same configuration with a matching firing order.
You still need to figure out the cylinder positions though since knowing the firing order itself won’t do much. Once you get to know the cylinder layout as well, that’s where the real drill starts with the engine’s maintenance so we’ll guide you through that as well.

As for the cylinder arrangement of both the LS2 and the L76 engine, things are once again the same. Both engines were GM’s creations based on the same base engine block and cylinder layout, so that makes it easier as you can’t go wrong with either one of them.
The first cylinder of the 6.0L engine is on the driver’s side along with cylinders 3, 5, and 7. On the other hand, cylinders 2, 4, 6, and 8 are on the passenger’s side, looking front to back.
Pontiac 6.0L vehicle applications
One final thing we need to do before we wrap up this guide is to give you a list of all the Pontiac models that were equipped with 6.0-liter engines. So, here’s what it looks like:
- Pontiac GTO
- Pontiac G8
- Pontiac G9
It’s worth pointing out that the GTO model is equipped with the LS2 engine, but regardless of that, the firing order is the same for all of those.
Our take
Ultimately, the Pontiac 6.0-liter engine should now run smoothly in your car after applying the firing order to check up on the cylinders. We hope you’ll find this guide to be helpful on that path, and make sure to pay attention to the cylinder numbering scheme before you do anything with the firing order.
