Description

Stop chasing junkyard Muncies and searching for worn-out four-speed cores. This comprehensive TREMEC Magnum 6-speed conversion package delivers modern supercar-level performance to your 1968-1974 Nova big block build. The Magnum is the aftermarket version of the TR-6060 found in factory muscle cars like the Dodge Challenger, Viper, and Chevrolet Camaro -- delivering the same brute strength and sophisticated engineering in a package designed specifically for classic applications.

With a massive 700 lb-ft torque capacity, the Magnum handles whatever your big block throws at it -- naturally aspirated, supercharged, or turbocharged. The double overdrive design gives you two cruising gears: fifth at 0.80 drops highway RPM significantly, while sixth at 0.63 lets you loaf down the interstate with the engine barely working. Choose between 2.66 or 2.97 first gear ratio sets to optimize acceleration versus highway cruising based on your rear axle ratio and intended use.

Inside, the Magnum delivers the precise, communicative shift feel that enthusiasts demand. Triple cone synchronizers on gears 1-4 and double cone synchros on 5-6 ensure smooth, crisp engagement even under heavy load. The fully reversible TKO-style die-cast aluminum shifter provides short, low-effort throws with positive action. Multiple shifter locations allow optimal positioning within your Nova's console, and dual speedometer pickups let you retain a mechanical speedometer or upgrade to an electronic setup.

This complete package includes every component required for a turnkey installation: transmission, bellhousing, clutch system, flywheel, hydraulics, crossmember, pedal assembly, wiring harnesses, and driveline components. MDL's guided package selection walks you through each choice, ensuring every part works together for your specific Nova and big block combination. Little to no tunnel modifications are typically required, and the shifter location retains that stock look and feel.
