Genuine OEM MOPAR Bare Block Cast Iron.
OEM replacement and factory orange color.
This was original equipment on 2012-2017 Jeep Grand Cherokees and 2015-2017 Challenger & Charger SRT Hellcat models with a 4.090" Bore. In 2018 They switched to the BGE Blocks found in the 2014 and newer RAM HD Trucks which is linked below.
When this Hellcat Bare Block is unavailable from MOPAR, we recommend using the Mopar Big Gas 6.4L VVT Bare Engine Block as a great alternative. It is the same casting as the Hellcat block. The only notable differences between this Hellcat block and the BGE (aka 392 Truck Block) is the exterior color (normally black on the BGE block, orange on the Hellcat version) and the bores on the BGE have not been torque plate honed. For most customer applications this does not affect their builds in any way since most engine shops can easily paint a block and engine shops are torque plate honing the cylinders again. The benefit of torque plate honing is that in theory it results in engines that produce slightly more horsepower.
