Expert tuners advice on timing advance vs octane/compression
5.3L motor 862 heads 210/218 .584/.584 116+4Lsa
For 9.5 compression with 87 octane what is a typical degree advance range?
with 93?
Getting my 862s milled .03 putting my compression around 10.1
Im curious as to how much timing I could run with 87 octane compared to 93 octane with 10.1 compression

I run 27/28 degrees of timing, alternating between 87 and 89 octane. Sometimes I get kr at low rpms, but never wot. I'm running the stock 9.5 compression ratio. I've got a buddy with a tbss that runs 22-24 degrees on 93 octane with 10.9 compression ratio, stock everything.
