Here's the full spec sheet:
This G3PP aluminum block is designed for use in builds up to 1,800 BHP. Not only is this G3PP block stronger than the factory Hellcat, "BGE" and Demon/RedEye engine block, it also offers huge weight savings, too. This G3PP block is 100lbs lighter than the OEM 6.2L cast iron block.*
Block Applications: The G3PP aluminum blocks are designed to be a direct replacement for the Hellcat and 6.4L Gen3 VVT HEMI applications. This block will also fit other 5.7L and 6.1L applications but will possibly need additional parts due to deck height and front cover/camshaft differences.
Block Material: Aluminum 357T6 aluminum alloy
Block Weight: Pending
Deck Height: Standard 6.2L Hellcat Deck Height. Sleeves are zero decked.
Deck Thickness: .600 minimum.
Cam Bearings: Cam tunnel is finish machined, bearings not included.
Note: When installing, BE SURE the oil hole in the bearings aligns with the oil feed hole.
Main Bearings: Main bore is left undersized, to be fitted by engine builder
Main Caps: Includes billet main caps. Center 3 main caps are 6-Bolt billet. Front and rear main caps are 4-bolt billet.
Main Studs: ARP 244-5400 Included. Torque specs on main studs are not the same as iron blocks: XXX ft. lbs. inner & XXX ft. lbs. outer with oil. (TBD)
Lifter Bores: Standard location. Lifter bore size is standard Gen3 HEMI diameter 0.842”.
Cylinder Bores: 4.050” standard semi-finished bore. Cylinder bores are of a siamese design. Max Bore of this engine is 4.185".
Sleeves: Sleeves are a replaceable, centrifugal cast ductile steel pressed in with a .001” to -.002” fit. Sleeves do not protrude into the water and are considered to be a DRY sleeve.
Freeze Plugs: None required

Filtration: Standard Integral mount for spin on filter.
Oil Pan: Accepts OEM style Oil Pans and windage trays. As with any Gen3 HEMI it may be necessary to hand fit the oil pan gasket to ensure stroker crankshaft clearance.
Cylinder Head Bolt Holes: Head bolt holes are designed for the factory 11mm size. If using studs (see G3PP Offerings) must use aluminum block style studs to prevent damage to your block.
Camshaft Tunnel: Made for 6.2/6.4L OEM VVT Camshaft Specs
Motor Mounts: Drilled and tapped for side mounts in OEM locations.
Bell Housing Pattern: Stock
Timing Cover: Accepts Hellcat, 6.4L and VVT 5.7L timing covers.
