Factory specifications for a 5.0L Chevy typically ranged from 8.5:1 to 9.5:1, but this could change with different camshafts, cylinder heads, and other modifications. High-performance builds can have significantly higher compression ratios.
To find the *actual* compression ratio for a specific 5.0L Chevy engine, you would need to:
* Consult the engine's specifications: If you have the engine's casting numbers, you might be able to find the factory specs online or in a repair manual.
* Perform a compression test: This is the most reliable way to determine the compression ratio, although it only gives you a snapshot of the current condition, not the designed ratio.
Without more information about the specific engine, providing a precise compression ratio is impossible.
