SP350/357 Turn-Key 350ci, 357HP / 407TQ Engine

Chevrolet Performance's line of Street Performance engines offers great power at a great value - and the latest is the SP350/357. It leverages the strength of a strong rotating assembly secured in a brand-new block with four-bolt mains, and matches it with modern valvetrain technology to support great high-rpm capability.

Economical Vortec iron cylinder heads deliver excellent airflow, while the latest intake manifold technology and a new hydraulic roller camshaft optimize airflow to push 357 horsepower and more than 400 lb.-ft. of torque! Better still, the engine is built with a durable rotating assembly set in a brand-new block with four-bolt mains. That's a feature you won't find on most rebuildable cores.

This SP350/357 Turn-Key package comes complete with the distributor, carburetor and balancer installed. The starter, fuel pump, air conditioning pump, alternator, front-end accessory drive kit and more are also included, but not installed for shipment purposes.
