Chev LSX376-B15 450HP Crate Engine GM Performance # 19417356

Chevrolet Performances engineers started with the tough LS steel Bowtie standard-deck block, added a forged-steel crankshaft, forged rods, and forged pistons, then topped off the short-block assembly with high-flow, rectangular-port LSX-LS3 six-bolt aluminum heads 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. Its perfect as an economical replacement for a late-model performer or a great choice to build a high-boost powerplant for a Pro Touring classic.

Durable Great for aggressive chewers
Color: Blue
Will make one whole room smell like fake bacon, but my dogs love it and it’s super strong and durable. I have a lab mixed with rotty and a full lab so it’s a perfect match.

Durable, Dogs love it
Color: Red
My Frenchie is a crazy chewer and can chew up a nylabone in a day, so I was looking for something that would last longer. So far this is holding up, and is pretty durable. Both my dogs like it a lot, it’s easy for them to grasp, and chewable but still very tough material. I suspect at some point it’ll wear down, but not for a while. The size was just as described / expected. Not too small and not too big

NOT FOR PLAYING CATCH.
Color: Blue
This toy is quite heavy, making it good for a chew toy or for fetch, but not for catch. It could very easily injure your dog as it damned near did mine.
