What is the compression on each cylinder a 5.7 liter motor?

There's no single answer to what the compression ratio is on a 5.7 liter motor. The compression ratio depends entirely on the specific engine design, not just its displacement. Different manufacturers, and even different models from the same manufacturer, will have varying compression ratios for their 5.7L engines.

To find the compression ratio for a *specific* 5.7L engine, you need to consult:

* The owner's manual: This is the best source.

* The engine's specifications: Often found stamped on a tag on the engine itself or in service manuals.

* Online resources: Searching for the specific engine code (e.g., LS1, Hemi 5.7) will often yield specifications, including compression ratio.

Compression ratios typically range from around 8:1 to 12:1 or even higher in some performance engines, but again, it varies greatly.
