I’d say the big reasons to go aluminum over iron are:
you could shave a couple 10ths off of your 1/4 time.
Second reason would he weight transference. The third would be because you just want it to look trick and the last would be because you’ve got several thousand dollars extra you really want to splurge on an aluminum block.

If i had an unlimited budget, I’d probably go aluminum myself. For most folks I think that the few thousand dollars you can save on an iron block would be better spent into other upgrades.
