BluePrint Engines BC408K727 Details

This BluePrint Engines crate engine package delivers 465 horsepower and 494 ft-lbs. of torque with a street-friendly 10:1 compression ratio, combining classic muscle with modern reliability. It features aluminum heads, a performance roller cam, forged pistons, and a durable cast crankshaft, all topped with a Holley 750cfm Classic Carburetor for strong throttle response and proven street performance. Paired with a performance-built 727 transmission and a 10-inch torque converter featuring a 2200–2600 RPM stall, this setup is built for crisp acceleration and drivability. The package includes all the essentials—thermostat and housing, fuel pump and line, spark plugs and wires, starter, distributor, air cleaner, harmonic balancer, timing cover, valve covers, oil pan, and a high-flow water pump. A polished front accessory drive system finishes it off with show-quality style, including a Type II power steering pump with remote reservoir, 140-amp 1-wire alternator, and 7B10 peanut-style A/C compressor, making this a complete, ready-to-run drivetrain solution for any serious street build.
