Power your classic truck, SUV, or project vehicle with the ultimate evolution of the small-block Chevy: the 5.7L 350 Vortec V8. As the final and most refined generation of the classic Gen I small-block, the Vortec 350 introduced high-swirl combustion chamber cylinder heads and a factory roller camshaft, delivering superior airflow, better fuel efficiency, and a significant bump in low-end torque compared to older TBI and carbureted versions.
Whether you are replacing a tired motor in a 1996–2002 Chevy/GMC truck (C/K1500, Tahoe, Suburban) or retrofitting a classic muscle car or hot rod with modern reliability, the 350 Vortec provides dependable, bolt-in horsepower.
Every engine is completely remanufactured, precision-machined, and thoroughly pressure-tested to ensure factory-spec tolerances, correct oil pressure, and long-term durability.
