Hey Chris do you think this would clear 87 octane?
.038 quench
50 Ivca
9:1 static
7.9:1 dynamic
That's half the quench area of stock with only .5 more dynamic compression

I can't really answer that. However, it is lower than what I run on midgrade so it may cut it. There are just so many variables that its hard to determine what will run on what octane.
