I wasnt aware it was. Aluminum disapates heat better than Iron. It weighs less, etc. etc. THe LS2, LS1, LS6, LS7 are all aluminum there is also an aluminum 5.3. At the time they were introduced, all were in the top of their class.

i would only go Iron for a high boost engine or an EXTREME N/A engine. Only advantage Iron blocks have (in the Gen III/IV world) is they can be rebuilt a couple times were as most of the aluminum blocks can only be bored .010 then need new sleeves. But what are your plans for the engine?
