Compression on a stock 440 engine typically ranges from 8.5:1 to 10.5:1, depending on the specific model and year. Higher compression ratios can improve performance and efficiency but may require premium fuel to prevent engine knocking. Modifications such as aftermarket pistons or cylinder head work can further increase compression, but they also necessitate careful tuning and consideration of fuel quality. Always ensure that any changes maintain engine reliability and longevity.
