New G3 Hemi Block...

Stock Gen III blocks are good for 800-900 horsepower.

Not sure about aftermarket.

This is what modern muscle xtreme told me when I sent them an email regarding block durability, BGE stands for Big gas engine(part number for the truck shortblock is 68226133AA ) which comes in the 2014-2019 RAM 2500 6.4 Trucks, the hellcats and the 392 scat packs from 2018 onward. just rip the pistons and rods and throw new ones, a cam and she's absolutely ready for some good eating. the heads on the G3 Hemi are so good they don't even need to be touched, hell Mopar uses the stock rockers and rocker shafts that come in the 6.4 for the hellcat and elephant. the Gen 3 aftermarket is huge now so it is definitely a cheaper engine to build than the LA. CNC motorsports and HHP have a lot of internals and stroker kits ($2,313.95 for a stroker kit that will punch out a 5.7L to 6.4L) for nice prices that will do more horsepower than any of us need so as much as I love my current 5.9 If i ever get the itch for more power it will be with a G3 hemi
