The Heart of the Beast: Hemi V-8 Power

Few engines command the respect that the 426 CI Hemi V-8 does. Under the hood of this Challenger lies a modern marvel built by the Block Shop. This powerhouse is constructed around a Mopar Performance Siamese block, ensuring a sturdy foundation for serious power. It truly is a modern take on a legendary motor.

Fueling this beast is a Mod Man intake system topped with twin Edelbrock carburetors and custom linkage. This setup ensures the 426 Hemi breathes efficiently at all engine speeds. The engine wears steel chrome valve covers, adding a touch of classic polish to the modern machinery.

For flawless combustion, the engine relies on an MSD pro billet distributor and a 6AL ignition system. The ignition features a Tight Curve set, which is crucial for optimal timing and power delivery. Champion 71 spark plugs complete the reliable, high-performance spark setup.

A Modern Shift: The 5-Speed Manual

Perhaps the most significant performance upgrade is the Tremec 5-speed manual transmission. This modern unit replaces the original gearbox, drastically improving the driving experience. Paired with a classic Pistol Grip shifter, it allows the driver better control over the engine’s considerable torque curve. Furthermore, this upgrade enhances highway cruising, which is always a welcome feature.

Power is reliably sent to the pavement through an 8 3/4 inch rear end. This driveline setup is robust enough to handle the engine’s output. The addition of air conditioning is another thoughtful, modern amenity that makes this vintage coupe a pleasure to drive in any climate.
