Aluminum is light, easily repairable if windowed, and you can resleeve if you hurt a cylinder. The ONLY downside is the cost.

Cast iron is heavy, it's a boat anchor if you window it, sure you CAN sleeve it, but not like an aluminum block.

In my opinion, if you have the money...there is only one way to go. That's why I have a KB block in my cuda. CHIP



I agree. There may be some here chime in about thermo/power loss. That's all BS. There may be some cylinder movement that can slightly affect ring seal but it's minimal compared to the advantages aluminum has over iron.
