BUDGET PERFORMER BLENDS BEST OF LS ENGINE FAMILY

Chevrolet Performance engineers have developed the LS364/450 as a value-driven foundation for hot rod builders and enthusiasts looking to give their earlier LS-powered vehicles a high-performance shot in the arm.

Starting with a strong, economical iron cylinder block and durable rotating assembly, the LS 6.0L features the high-lift LS6 camshaft and the deep-breathing LS3 aluminum cylinder heads. Its a strong combination with exceptional horsepower and a broad torque band. It is also fuel injection-capable, using production-based components offered in this catalog.

The LS364/450 is designed with the early-style 24X crankshaft and 1X camshaft sensors, enabling easier retro-fit installation in early LS-powered vehicles, including 19982002 Camaros, C5 Corvettes, 19992006 full-size trucks and SUVs, and other LS vehicles.

We offer the LS364/450 exclusively as a long-block assembly, without the induction system, ignition system or front-end accessory drive system, allowing builders to transfer components from their early LS-powered vehicle or complete a custom build with the components of their choice. An intake manifold that matches the LS3/L92-style rectangular intake ports is required.

No matter which vehicle you drop the LS364/450 into, its combination of horsepower and value will push your project vehicle to the next level of performance!

Great tennis shoes!!
Size: 4.5 Big Kid, Color: Black/Orange
The best shoes my son had this past year. He loves them and has worn them continuously, not only for running and training, but also for daily use. He really likes them and says they are very comfortable.

Size up
Size: 2 Big Kid, Color: Black/Pink
My daughter loves them. However they run a size small so we had to size up. She is anywhere from a 13-1 and we had to get a 2 in these. Overall great show and quality. She also just learned how to tie her shoe (7yo) and they are easy for her to tie. Style is great for running and sports too. Overall great value for the money.

These shoes make a great first impression, but beware of the stingy toe box.
Size: 13.5 Wide Big Kid, Color: Black/Orange
These shoes make a good first impression. They look sharp and appear to be well-made for running shoes. They also get bonus points for having actual laces instead of the common velco/fake laces combo. However, my son struggled to get them on at first due to limited room in the toe box. He has wide feet as well as high arches and the shoes were very snug across the top of his foot initially. Once he got them on, we determined that they were both wide enough (which is a rarity in itself) and the right size – just tight across the top. I actually had to remove the insoles to get them on his feet at first. After a few minutes I tried again with the insoles and he wore them around the house for a few hours, at which point the upper material had relaxed and/or the footbed had started to take on the shape of his foot, in effect creating more wiggle room. By then he didn't want to take them off, so they must have gotten more comfortable after that brief break-in period. If they were still too tight I'm sure he would have complained. I'll update the review if the shoes wear out prematurely or there is anything else noteworthy to report.
