The BLUEPRINT ENGINES 426 Gen-III Hemi crate engine is a fuel-injected, dyno-tested powerplant built for Chrysler and Mopar enthusiasts who want modern drivability with classic displacement. Rated at 610 horsepower and 525 ft-lbs of torque, this 426 hemi crate engine arrives deluxe dressed and ready to drop into a Gen III Hemi compatible chassis. It runs a street-friendly 10.48:1 compression ratio, so it lives comfortably on pump gas while still pulling hard. For builders restoring a muscle car or finishing a pro-touring project, this is a complete, balanced long block that takes the guesswork out of a high-output Hemi swap.
The foundation is a new BGE Hellcat/Apache cast iron block with a 4-bolt main, 4.090-inch bore, and one-piece rear main seal. Inside sits a forged steel crank with a 4.050-inch stroke, forged pistons, and 6.125-inch connecting rods, internally balanced to within 2 grams. Gen Three Hemi Apache aluminum cylinder heads use 73cc chambers with 2.140-inch intake and 1.650-inch exhaust valves. A hydraulic roller cam delivers 0.610-inch intake and 0.611-inch exhaust lift on a 113-degree lobe separation angle. Fuel delivery runs through a Holley Terminator ECU with wiring harness for tuning control. The package includes a black pulley kit, water pump, type II power steering pump, 140-amp alternator, A/C compressor, harmonic balancer, valve covers, timing cover, spark plugs, and coils.
This crate engine suits Mopar restomods, B-body and E-body restorations, and custom builds that need a turnkey Hemi without sourcing parts piece by piece. It ships with a muscle car style mid-sump swap oil pan and holds 6 quarts with the production pan. Each unit is dyno tested before it leaves the shop and carries a fully transferable 30-month, 50,000-mile parts and labor warranty. Manufactured and machined in the USA. Pair it with the right oiling system components and spare oil filters, or browse our full engines and components selection to complete your build.
It is rated at 610 horsepower and 525 ft-lbs of torque per manufacturer specifications. Each engine is dyno tested before shipment, so the numbers reflect verified output rather than estimates. The 10.48:1 compression ratio keeps it pump-gas friendly for street use.
It is fuel injected and managed by a Holley Terminator ECU controller kit with a complete wiring harness. That setup gives you modern cold-start behavior, tuning control, and drivability that a carbureted Hemi cannot match out of the box.
The engine ships deluxe dressed with a black pulley kit, water pump, type II power steering pump with remote reservoir, 140-amp alternator, 7B10 A/C compressor, harmonic balancer, timing cover, valve covers, spark plugs, coils, and a mid-sump swap oil pan.
BLUEPRINT ENGINES backs it with a 30-month, 50,000-mile parts and labor warranty that is fully transferable. The engine is manufactured and machined in the USA. Some third-party listings show a shorter term, but the manufacturer figure is the authoritative one.
It is built as a drop-in ready crate engine for Chrysler and Mopar Gen III Hemi compatible applications. The mid-sump swap oil pan is designed for muscle car chassis clearance, making it well suited to B-body and E-body restorations and custom builds.
