360 timing

Well it might run on pump gas...... at 6000plus ft elevation. I run 87 at 900ft at 10.7 static with aluminum Eddys and a Hughes [email protected]. I seem to remember the dynamic was in the mid 8s. Maybe 8.7? I forget.Ran around 185psi when fresh with filefits.
-Yeah for sure a compression test can help determine fuel type.And aluminum heads suck a ton of heat out. I ran a tick over 200 on 93 with flattops and .020 quench, for a while. That motor flew.
