Chevrolet Performance SP350/357 Turn-Key Crate Engine

SP350/357 Turn Key Crate Engine

Here it is – the most legendary turn-key engine in hot rodding history. Whether you’re taking on a painstaking restoration of a beloved Chevy pick-up, or looking to light up the tires on your rat rod, and everything in between, the SP350/357 is the ideal engine choice. Chevy Performance’s newest iteration of the small block wonder keeps the time-tested architecture but adds modern improvements for increased reliability and usable power across the rpm range. 

With 357 hp and 407 lb.-ft. of peak torque at just 4,000 rpm, the Karl Kustoms Chevy SP350 turn-key motor features:

• Hydraulic roller camshaft for optimized airflow
• All brand new components – not remanufactured, including the block and four-bolt main caps, as well as a durable nodular iron crankshaft
• The latest small-block dual plane intake manifold technology
• High-quality engine accessories
