Killshot EFI 4bbl w/Fuel Delivery Kit Blk

The Killshot EFI 4bbl w/Fuel Delivery Kit Blk by ACES FUEL INJECTION represents a complete modern fuel system solution for classic and custom vehicles transitioning from carbureted to electronic fuel injection. Designed for builders and enthusiasts who demand reliable, street-proven performance without compromising original aesthetics, this 4-barrel EFI system eliminates the tuning headaches of traditional carburetors while delivering consistent fuel metering across all engine loads. The included fuel delivery kit streamlines installation, making this an ideal choice for restorations, engine swaps, and performance builds where precision fuel control matters.

This carburetor-replacement assembly integrates electronic fuel injection technology into a compact, four-barrel form factor that bolts directly to standard 4-barrel intake manifolds. The bundled fuel delivery kit includes the pump, filter, and pressure regulation components necessary for plug-and-play installation, eliminating multiple sourcing trips. The black powder-coat finish resists corrosion while maintaining a clean appearance under the hood, and at 26.65 lbs, the system's weight distribution supports both small-block and mid-sized engine applications. ACES engineered this platform to maintain cold-start reliability, precise idle control, and seamless acceleration across ambient temperatures—critical factors that separated early EFI conversions from modern standards.

Hot rod builders, muscle car restorers, and truck enthusiasts benefit most from this system, particularly those retrofitting vintage vehicles with modern driveability. The Killshot EFI 4bbl works seamlessly with both carburetor-style intake manifolds and aftermarket EFI-specific manifolds, provided they accept 4-barrel mounting plates. Installation requires basic mechanical skill and a compatible engine control module (ECM) or standalone EFI controller; consulting wiring diagrams specific to your donor engine ensures optimal tuning. This kit delivers the horsepower consistency and fuel economy gains modern drivers expect while preserving the classic look enthusiasts demand.
