The super charger "trumps" the entire deal. You will have to take out some compression to effectively manage any boost, how much depends on the final boost the engine will see at peak load?
You can make PLENTY of power on low octane fuel without one, and still have a engine that is relatively "mild" at a glance, and conservative drivetrain parts.
This is one of the best attributes of running a Pontiac engine right to start with.
You can get-er done with less of everything, and still have a dead solid reliable set up that will provide many years of enjoyment without a lot of wrench turning on it.
My engine uses a 76cc version of the KRE heads, right at 11 to 1 compression, and easily manages 87-89 octane fuel with zero issues.
Since many folks think that I operate "outside the box", these engines run fine down around 10 to 10.5 to 1 compression, just giving up a slight amount of power and rougher idle quality.
In any case, what you want to do is easy, choose the cam wisely, and keep the quench distance tight, zero decked block, etc......Cliff
