Default compression ratio
Group,

Does anyone know appx compression ratio of a L48 if you install 64cc chamber heads, and make no changes to the stock pistons? Original heads for 1977 L48 are 77cc chamber, and I think yield 8.5:1 Thanks for the help. Chris

64cc will add more punch to OE L48 ... but CR will be much closer to 9:1.
