FORGED INTERNALS SUPPORT MORE BOOST!
For builders who want to stretch the performance of a turbocharged or supercharged combination, Chevrolet Performance's LSX376-B15 is the foundation they need! Its durable, all-forged rotating assembly supports up to 15 pounds of boost. Our ratings of 473 hp and 444 lb.-ft. are only an indication fo what the engine is capable of.
Additionally, the engine is topped off with high-flow, LSX-LS3 6-bolt rectangular-port heads to create an affordable foundation for supercharged and turbocharged combinations. We deliver the LSX376-B15 without an intake manifold and other accessories, allowing you to tailor the induction system and other features to suit the forced-induction setup of your choice.
Our horsepower and torque ratings are based on testing with the production-style, normally aspirated fuel injection system. The power you make with a supercharger or turbo will vary.

PRODUCTS ON OUR SITE should be viewed as a Catalog of Genuine GM OEM Auto Parts & Accessories. They are subject to availability and may be discontinued or have a superseded number without us having been updated by the manufacturer.
Some Parts are “On-Hand” or “in-stock” and come from our physical location. Others are sourced from our direct GM suppliers. On occasion, some items become unavailable or are understocked without our knowledge. GM provides us with updates continually, but this is not always reflected immediately on our store site.
We make every effort to communicate with you via email regarding any questions, updates or changes about your order throughout the process. If an item cannot be supplied, you will not be charged or a refund will be applied for that particular part or order as needed.
Shipping prices quoted on your final order may be subject to change based on actual packaging box size + delivery logistics. The dimensions x weight seen on a product page is for the actual part or accessory itself, not necessarily the packaging box used. This can affect the later shipping rate calculations. We make every effort to give you the best rate on your order and will consult with you on changes.
Orders with a VIN number provided are recommended and verified for accuracy.
Any illustration is a simple rendition of the part and where it is located on the vehicle; it is for reference only. Factors such as trim, color, and options are not depicted in the illustrations. Check with us if a part or accessory stock photo shows a color style to make sure what is ordered will be that color.
