And I have to ask again... Why would you NOT use block fill??? Such cheap insurance to keep those thin walls from moving around all it can possibly do is add performance and longevity to the engine.

I use block fill on anything that is going to the track for the performance improvements it brings to the engine by keeping the cylinders stable.... the fact that it helps keep the engine together is just a bonus....
