Hiperformer offers an extensive selection of high quality remanufactured Chevy 350 engines. Our 350 V8 motor built to improve your vehicle or boat performance. We have been building the GM Chevy 350 long blocks for almost forty years and still going strong. See what previous Chevy 350 buyers had to say about the quality of our engines, the warranty and the customer support. All our Chevy 350 long blocks come with cylinder heads attached and valve train installed. Keep your old valve cover, timing belt cover, intake manifold and oil pan. You will need to install them on the new Chevy 350 engine.

We offer 7-years or 100,000 miles warranty on all the GM passenger cars and light trucks.

We can custom build the Chevy 350 engine to meet your power and performance requirements. To learn more about our GM 350 specification, customization and warranty, visit the FAQ page.For ease of use, we have listed our catalog of Chevy 350/5.7L V8 engines in two groups, marine and automobile.
