Pro-Flo 4 EFI Kit SBM 318-360 625 HP

The Pro-Flo 4 EFI Kit for SBM 318-360 from Edelbrock represents a complete, bolt-on fuel injection conversion system designed for small-block Mopar enthusiasts seeking modern engine management without sacrificing mechanical simplicity. This sequential multi-port injection solution transforms carbureted 318 and 360 cubic-inch engines into electronically controlled powerplants capable of delivering a consistent 625 horsepower. Whether you're restoring a classic Dodge muscle car, upgrading a street rod, or building a performance cruiser, this kit eliminates the tuning variability and vapor lock issues inherent to carburetion while maintaining the classic aesthetic of your build.

The system employs sequential fuel delivery through eight individual 35 lb/hr injectors, ensuring precise metering at each cylinder for superior cold-start response, idle quality, and throttle transition. Its 1000 CFM airflow capacity accommodates aggressive cam profiles and high-rpm operation, while the aluminum construction keeps overall weight minimal—critical for maintaining your vehicle's balance and handling. The square-bore mounting design integrates cleanly with most small-block Mopar intake manifolds, and the natural aluminum finish blends with period-correct engine bay aesthetics. Sequential injection timing follows your engine's firing order, delivering fuel only during the intake stroke, which maximizes combustion efficiency and reduces emissions compared to batch-fired or bank-to-bank systems.

Installation is straightforward for experienced builders with basic fuel system knowledge; the kit includes all necessary injectors, rails, and plenum components fitted specifically for 318 and 360 displacement variants. Compatibility extends across decades of small-block Mopar applications, from first-generation A-bodies to modern restomod platforms. Tuning is handled by a stand-alone ECU engineered for Mopar-specific parameters, allowing you to dial in idle quality, fuel maps, and ignition timing without proprietary scan tools. This Edelbrock system is ideal for builders prioritizing reliability, driveability, and performance without the complexity of carb-to-EFI adapters or aftermarket standalone systems.
