BluePrint Engines BPC4085CTCKB Details

This BluePrint Engines crate engine is a complete, turn-key powerplant producing 465 horsepower and 494 ft-lbs. of torque with a street-friendly 10:1 compression ratio, perfect for classic car restorations or high-performance street builds. It features aluminum heads, a smooth-operating roller cam, forged pistons, and a cast crankshaft for long-lasting reliability and power. Fuel is delivered through a Holley 750cfm Classic Carburetor, supported by a fuel pump, fuel line, spark plugs, and plug wires, while cooling is handled by a drive-side inlet water pump, thermostat, and thermostat housing. The engine comes fully dressed with a harmonic balancer, timing cover, valve covers, air cleaner, distributor, and oil pan, making installation easy. Completing the package is a black front accessory drive system, which includes a water pump, Type II power steering pump with remote reservoir, 140-amp 1-wire alternator, and a 7B10 peanut-style A/C compressor—blending show-car looks with street-driven reliability.
