nobody cares about what you are running
well besides me. sleeved engines are a much different breed. I would say it depends on the application. imo anyway to add strength to a block or dampn harmonics, the better. I would believe some strength is lost in thermo properties in a empty block. Cylinder heads I am on the fence about filling them. on my engines or heads they are not filled, unless it is for a sponsorship and my arm gets twisted hard enough.
