AFFORDABLE SMALL-BLOCK PERFORMANCE!

If it’s affordable performance you’re looking for to power your project vehicle, Ohio Speed Shops SBC350/380 delivers! With 380 horsepower and a deep reserve of low-rpm torque, it quickly reminds you why the 350 Small Block Chevy has been the industry benchmark for decades.

The OSS 350/380 leverages the strength of a strong rotating assembly, along with upgraded Vortec cast-iron cylinder heads. A roller camshaft optimizes drivability and airflow capability.

It all adds up to a 24-horsepower gain over our 350 HO crate engine – and a great, affordable alternative to rebuilding. Our base crate engine package includes an assembled long block, including the oil pan and balancer. You finish it off your way, with the ignition system, induction system and additional accessories.
