    Iron block only downfall is the weight of iron. BUT iron does not heat up like aluminum. If your planning on major power, or just straight up reliability, go iron. If you want to shave 100 pounds off the nose of your car, then go aluminum. They do have some really , really strong aluminum blocks out right now. Ether way, horsepower is made.

    Personally, I would only go iron if I wanted to make a crazy amount of power.

    There are FI LS2 blocks in the 1000 rwhp range and up. I think Mike and Steve were making somewhere around 1300 if I remember correctly, but that was pushing the limits pretty far.
