Gen X Billet Engine Block

The Modular Motorsports Racing 444800 Gen X is a revolutionary billet engine block engineered for the demands of high-performance Coyote engines. This block is designed for enthusiasts aiming to achieve power outputs between 1800 and 4000 HP while maintaining exceptional reliability. It has been proven in extreme racing conditions, capable of supporting mid-5-second 1/4 mile times and 3.72-second 1/8 mile runs at over 212 mph. Constructed from aerospace/military-grade 7075 Billet Alloy, the Gen X block offers unparalleled strength and durability over traditional cast blocks with sleeves. Key features include gigantic 9/16" cylinder head threads, oversized 1/2" inner and 7/16" outer ARP main studs, and screw-in oil galley plugs with O-rings for a leak-free design. The block incorporates thick, replaceable flanged sleeves for optimal cylinder ring sealing and can be bored up to 3.740". It utilizes an 8-bolt main configuration with two ARP side bolts per side, enhancing stability over the factory one-bolt design. It also retains standard factory provisions for motor mounts, dry sump pump systems, and A/C mounting. The billet alloy construction also allows for repairability in the event of catastrophic failure through welding and re-machining, restoring the block to like-new condition. This engine block is compatible with 5.0L and 5.2L Ford Coyote engines and is available for both short and tall deck configurations.
