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.*



Specifications:

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

Oil System Features: Block is set up for OE style internal oil pump.

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.



Now Fully Manufactured in the USA!

That 4.185 bore with a 4” arm comes in at 440”

Not saying I would run that much stroke w stock deck ht but that’s gonna excite some people : )

What is the OD of the steel sleeve? Site says 4.185 max bore. According to who? Same people that can’t determine what to torque the arp mains too? Lol. Different builders have different opinions of what minimal wall thickness is.

Liking the undersized mains myself but that also might mean that there will be used blocks available in the future that are f*****up. How many shops do you trust to align bore these days?

What I don't get is why haven't more manufacturer's been going to a girdle over main caps? They seem to be much stronger. That's how the F20c engine in the S2000 is from factory and those engine are extremely strong. So much so that there are boosted stock crank and blocks making upwards of 2000 hp, on a 4 cylinder.

Manufacturing/production cost and space I’d assume. Not sure manufacturers are trying to make their factory capable care capable of withstanding 2000 hp lol. Plus, the power is spread out on 8 cyl. Pressure per cylinder/piston is a lot greater in a 4cyl depending on power output, may be why a girdle is used there over main caps

Yeah, I guess that makes sense then.

Don’t those Honda blocks come with the pan rail at the centerline of the crankshaft? Every generation of Mopar Hemi block is skirted and the mains are cross bolted. Granted this block is aluminum not iron but until someone builds one and proves there is a need for a girdle (caps moving) I wouldn’t worry about that

Not sure what you mean by pan rail. There is a 3 inch (I believe that's about the size) tall girdle and across each crank bearing section is a cross beam. The girdle is a one piece item the size of the bottom of the block and then the oil pan bolts to it. Below is an image of it.

 

[SickToo]

The pan rail is just what builders call the surface that the oil pan bolts to. It’s usually the lowest part of the block. Engines that have the pan rail at the center line of the crankshaft (like a Chevy v-8 (350 or 454) or a small block Mopar LA motor 272-360) have the main caps hanging down into the oil pan unsupported. Skirted blocks have the pan rail down below the main caps which makes it possible to cross drill the caps (Mopar did this on all generations of their hemi) for additional support. No need for a girdle

[Unholy707]

How can I get sponsored for this? Can be at the track every day/weekend 365 days a year

 

[Unholy707]

At this point it’s a street legal drag car, will gladly take saw to car and gut it like a fish for sponsorship

 

[Leopapio]

Shoot if thats the case ill send you guys my hellrango for aslong as you need it, itll be "research and development" onlything i ask in return is i get atleast a 1200awhp Hellrango back..... oh perferably with beefed up powertrain dont want to snap anything shuttling the kids to school a 1/4 at a time 😇

Worlds fastest Hellrango anyone?

 

[HighHorseman]

Hate to break it to you guys, but even sponsored racers mostly pay for their parts

You know how the saying goes beggars cant be choosers lol

Shoot I'd be happy with you guys sponsoring me by putting me 1st in line lol
