Deck plate Duramax engines are proven winners in both power production and durability. Our 1" deck plates are manufactured in the USA with A36 hot formed steel. A robust steel resistant to warping with a tensile strength as high as 80,000psi. If your looking for the ultimate in Duramax durability, you should be considering a solid block, deck plate engine.
Features:
- Oversized Oil Drain Back Holes
- Improved A36 Billet Material vs Competitors
- Includes ARP Deck Installation Hardware
- Includes Dowel Pins
- Blanchard Ground to 1.010" for Flatness
- Ball Milled Sealing Channels on Oil Holes
Things to consider:
- This plate will require finish machining after installation
- Deck plate engines require the use of cylinder sleeves
- Advanced machining is required to attach these to your deck surface
- A 1" longer custom connecting rod and pushrods will be required
- Intake, Bridge, Up-pipe and Accessory mounting will not longer match OE.
