AN AFFORDABLE SMALL-BLOCK PERFORMER READY TO RUN!
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 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.
Our 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, ready to bolt on.
Chevrolet Performance also offers the SP350/357 Base crate engine, P/N 12677167 as well as the SP350/357
