I understand that a new Hemi block is a large purchase. Why would you spend $5500-6000 for an iron block when you can get an aluminum one for $1500 more? Repairable and 150 lbs lighter.
Because it will be street only and I don’t want a block that ‘moves’ around in the cold to hot cycle and please don’t say aluminum won’t grow. Besides it’ll look dumb with cast iron heads.
Paint and headers hide a lot of sin😁
Besides, aluminum requires some extra care, bur it isn't unworkable. Run a bit tighter main bearing clearance, expect .008 to .010 deck hieght growth, and i would go aluminum heads as well if you can budget for it. Now you have a kller hemroid, and about 150 lbs less up front!
