question about octane and CR

[19Yukon97]

hey guys.

Just had a quick question... What would be a good compression ratio for 89 octane? Its for my 383 build, im doing my research to complete the build, and was just wondering what you guys thought about the CR for it, without going with 93 octane.

actually what do you guys think about CR with 91 octane?

Dynamic compression ratio is more important ... head chamber design, chamber size, head material, timing, quench, plugs are all going to effect your ability run lower octane with your setup ...
