New 3G Hemi 460HP Engine with 4L60E 4-Speed Auto Transmission Combo Package
Pace Performance is breaking new ground with the launch of the new Connect-and-Cruise 3G Hemi And automatic Trans Package. For years, Dodge, Plymouth, Chrysler and all Mopar enthusiasts have struggled with little manufacturer support to take one of these amazing late model Hemi engines, and install them into their classic Mopar muscle car. Let Alone put a reliable automatic overdrive transmission behind it without tacked on vacuum and toggle switches! Our Pace Performance engine techs have taken the newest design Eagle Hemi, and added numerous longevity and HP producing revisions to offer you this 460 horsepower power plant. You read that right! Almost 100 horsepower more than a 5.7 Challenger! There’s no complicated tuning or wiring here! This is our complete turnkey package that features all sensors, harness, ECM, and even our famous Pace Prime and Prep Package. To make this a true connect and cruise package, we added a Holley Dominator ECU, a 4 speed auto, electronic transmission that is specifically built for this power level, and provided you with the crossmember, hardware, and even the bolts to fit one of these combo's into your Mopar Muslce Car!
