Killshot II 4bbl EFI Gold

The Killshot II 4bbl EFI Gold by ACES Fuel Injection represents a modern advancement in carbureted engine conversion technology, purpose-built for classic car enthusiasts and serious hot rodders looking to upgrade aging fuel delivery systems without sacrificing authenticity. This four-barrel electronic fuel injection solution bridges the gap between vintage aesthetics and contemporary reliability, offering fuel-injected performance in a form factor that respects traditional engine bay layouts. Whether you're restoring a muscle car, drag racing a vintage platform, or building a street rod, the Killshot II provides the precision fuel metering that modern driving demands while maintaining the visual integrity of your original vision.

The Killshot II 4bbl EFI Gold utilizes ACES Fuel Injection's proven electronic fuel management system, delivering accurate fuel atomization and distribution across all four barrels through programmable EFI controls. The gold finish designation indicates premium-grade corrosion resistance and durability, critical for long-term reliability in high-heat engine compartments where traditional carburetors struggle with vapor lock and fuel varnishing. Cold-start capability, load-based fuel mapping, and seamless throttle response eliminate the stumbling, flooding, and mixture inconsistencies inherent to mechanical carburetors, while the integrated ECU compensates automatically for altitude, temperature, and load conditions—something carburetors simply cannot achieve without constant manual jetting adjustments.

This system excels for restoration builders, bracket racers, and street rodders who need plug-and-play fuel injection without fabricating custom intake manifolds or relocating fuel tanks. The compact footprint and traditional four-barrel mounting interface minimize modifications to existing engine bay configurations, making installation accessible to shops already familiar with carburetor replacement procedures. Weighing 14.9 lbs with overall dimensions of 14.3 x 8.7 x 22.4 inches, the Killshot II fits within factory hood clearances on most classic platforms while delivering the fuel economy, cold-start reliability, and consistent performance that modern fuel injection technology provides.
