New Connect and Cruise Packages

Chevrolet Performance is breaking new ground with the launch of the new Connect-and-Cruise crate powertrain systems. They’re factory-engineered engine-and-transmission combinations that include all the electronic control modules, wiring harnesses and other key components you need with the simplicity of one part number. The CPP engineers matched the engines and transmissions for optimal performance and durability, so you can wring out all the horsepower from them with total confidence. The specially calibrated controllers are designed for retrofit installation in older vehicles, for easier and quicker installation and operation, without the need for third-party tuning.

Pace Pass-Thru Can & Tach lead harness

Derived from customer request Pace Performance delivers the popular LS3 in a new muscle car “swap ready” crate engine. Pace removes the current Chevy production oil pan and installs a low profile LS swap oil pan. Most aftermarket serpentine accessory drive systems include a water pump and balancer so these are also removed. Since the ATI balancers are used in most serp. drive kits Pace indexes and drills the crankshaft for pin/keyway needed for the ATI balancer. Pace then installs the HeatShield Products I-M Shield™ intake manifold heat barrier for consistent intake air temps and the rocker arms get beefed up with HD roller trunions. Also included is HP Tuner’s 6110 code scanner/reader which can be upgraded for custom tuning with purchase of additional software. Also available in 430HP & 525HP versions and the Connect & Cruise powertrain packages.
