Furthermore, due to their robust design they could handle more abuse than other engines at the time meaning they could last longer too! Ultimately, these things combined have allowed GM's Gen III LS Series to become an iconic part of automotive history; one which is sure to remain there for years to come.

How do I know what LS engine I have?

Not only is it important to know what type of LS engine you have, but also the year and model. To determine this, the easiest way is to look up the Vehicle Identification Number (VIN) located on your vehicle's dashboard or registration papers. The 8th digit in the VIN will tell you which RPO code was used when manufacturing your car. From there, you can identify your engine make and model. For example, if you are looking at an engine with a VIN that reads: 1G1YY32PXY5123456; the 8th digit would be a "P", signifying that it is an LS1-based engine from 2000-2002. If it were an "8" instead of a "P", then it would signal that this is an LS3-based engine from 2008 onwards. Knowing exactly what kind of LS engine powers your vehicle helps ensure a smoother ride for years to come as well as giving insight into its potential capabilities for modifications and enhancements down the line.
