Starting a 572 hemi build. Was wondering what people's opinions are on if the aluminum block is worth the $$ over the iron block?

Car will be naturally aspirated , mostly street car.

Thanks

The differences in the expansion rate of the aluminum block and the steel or iron sleeves makes me not want to run a aluminum block on a N/A motor, race or street, I hate engines that smoke from oil I'm sure now with all the LS3 and up LS Chevy motors out there that have aluminum blocks that you can make a aluminum block motor not smoke from oil consumption But I do know you can make more power and have a longer ring seal life with iron blocks compared to aluminum street blocks It's your choice
