GMP-19301326-MC Pace LS3 430HP Base Muscle Car Swap Engine with Installed Holley Swap Oil Pan.
As delivered, the Pace LS376/430 Muscle Car Engine is configured with popular upgrades and deletions that customers have previously requested.
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. Also available in 480HP & 525HP versions and the Connect & Cruise powertrain packages.
Starting with the '08 Corvette, the world was first introduced to GM's latest small block V8 creation the 6.2-liter LS3. A continuation of the industry leading V8 engines from GM Powertrain, the LS3 kicks out 430 horsepower and 424 lb.-ft. of torque. (In the Corvette, those numbers go to 436 hp and 428 lb.-ft. of torque with the optional dual mode exhaust system.) It's a brute of a small block with 376 ready cubes at your beckon call.
