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.

Great product to keep moisture in
Size: M (up to size 9)-Beige
These are so cool. I was skeptical at first. After an at home pedicure I put lotion on and keep these on for about a few hours. The moisture retention, and comfort and fit or absolutely amazing!

These work!
Size: M (up to size 9)-Beige
I’ve had dry cracked feet my whole life. Tried these last night with lotion from Trader Joe’s and literally overnight my feet are the softest they’ve ever been. I put a pair of socks over them and went to sleep with them on. Hard to walk around with all that slippery-ness but worth it! 10/10✨👌

A quality, glitzy little bottle of shine
Color: #07 Golden, Size: 0.17 Ounce (Pack of 1)
Lovely spray shimmer POWDER, really great for just spritzing on. The little bottle is adorable, easy to carry in your bag (has a little safety lid) and great for a little gift. It gives little puffs of glittery powder and it stays nicely, though I almost never perspire.
