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.
