Chevrolet Performance 19370163 - LS364/450 Longblock Crate Engine


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. It’s a strong combination with exceptional horsepower and a broad torque band. It is also fuel injection-capable, using production-based components offered from Chevrolet Performance.

Horsepower 452HP @ 5600RPM
Torque 441FT/LBS @ 4800RPM
Compression Ratio 10.3:1
