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.

A Genuine Game-Changer for Manufacturing Management
Color: Matte Black, Clear Lenses, Size: Standard
A Genuine Game-Changer for Manufacturing Management These glasses have been nothing short of life-altering for my career. As a production manager overseeing a manufacturing facility, documenting Standard Operating Procedures (SOPs) has always been a significant hurdle. My primary goal in purchasing these was to record high-quality POV video of processes, which I can then feed into AI tools to generate written SOPs. This isn’t just a win for my productivity; it’s a win for my crew, as it finally provides them with the clear documentation they need to succeed, relieving me of the stress that comes with inconsistent training materials. **Design & Comfort** I initially opted for the larger frame, but the height was a bit much aesthetically for my face. The standard size, however, is excellent. I have a history of headaches from standard eyewear after long days, but these remain comfortable for extended wear. They are impressively discreet—I had multiple people compliment them on day one without ever realizing they were smart glasses. They are convincing enough to pass as normal eyewear to the untrained eye. **Performance & Battery** * **Video & Audio:** The video quality is surprisingly clear, and the microphone performance is exceptional. I’ve taken several calls while wearing them, and the recipients couldn’t tell the difference between these and my phone’s handset. The audio is solid—provided you keep your expectations realistic regarding the low end. The bass is sufficient for daily listening. * **Battery:** This is the one area that requires adjustment. You’ll get about 30+ minutes of continuous recording, which drains the battery quickly. However, the charging speed via the included case is remarkably fast, which helps mitigate the downtime. **The "Unexpected" Features** While I bought these for SOP documentation, the note-taking and translator features have been revelations. On the production floor, I’m constantly pulled in four different directions. When I need to track material requests or quick process changes on the fly, these allow me to capture information immediately so nothing slips through the cracks. It has turned a single-use tool into an all-day essential. **Verdict** I am currently investigating sourcing safety-rated lenses to integrate these into my daily shop-floor workflow. While the frames themselves aren't officially safety-rated, for office-based procedures and light floor work, they have already become a staple of my daily routine. Between the hands-free note-taking, clear communication, and the efficiency they bring to training, these are an incredible value for anyone in a management or technical role. **Pros:** * Excellent microphone and video clarity. * Inconspicuous, stylish design. * Invaluable for hands-free documentation and note-taking. * Fast-charging case. **Cons:** * Battery life is limited during heavy recording sessions. * Frame is not officially rated for high-impact industrial safety environments.

She loves them!!
Color: Matte Black, Clear Lenses, Size: Standard
Bought these for my daughter that is a content creator.. she does cooking and food reviews.. She absolutely loves these glasses!!!! They aloud her to free up her hands and not have to worry about holding her phone or using a tripod as much.. the video and picture quality is great.. I've heard her both listen to music and talk on the phone with them. They also look great on her. She is going to add her prescription lenses to them.. These meta gen 2 glasses are pricey ($322 plus tax on sale).. But if you creat content even at the regular price its a no brainer..
