I am not familiar with the new hemi engines.

Does it have 2 or 4 bolt mains, plus side bolts into the mains?



The cast iron blocks have 2 bolt mains plus side bolts. The aluminum blocks will also have additional 4 bolt mains and side bolts on the #2,#3 & #4. The cast iron Hemi engine weighs in around 450 lbs less fluids. The aluminum Hemi block weighs 85 lbs less putting the engine at 365 lbs. You can feasibly get 468 cubes out of the aluminum block Hemi.
