Engine management is handled by a Holley Terminator ECU controller kit and wiring harness, providing precise control over fuel injection and ignition. Key components like spark plugs, coils, timing cover, valve covers, harmonic balancer, and a muscle car-style mid-sump oil pan make this engine swap-ready. The polished front accessory drive system includes a high-flow water pump, Type II power steering pump with remote reservoir, 140-amp 1-wire alternator, and a 7B10 peanut-style A/C compressor, blending function and show-quality looks. With the strength and overdrive capability of the 4L80E transmission, this package is ideal for high-powered street machines demanding modern reliability and supercharged performance.
