The Chevy 350 small block is the most produced American V8 engine in history. Introduced in 1967 by boring the 327 to 4.00 inches, the 350 went on to be used in more GM vehicles across more model years than any other engine. From the 1967 Camaro to the 2002 Chevy Express van- 35 years, dozens of applications, and tens of millions of units- the 350 small block is the universal American V8.
Three major evolutionary steps define the 350 for buyers today. In 1987, GM introduced hydraulic roller lifters across the SBC lineup- a significant durability improvement that eliminated flat-tappet cam wear. In 1992, the LT1 reversed the cooling system flow for better performance. In 1996, the Vortec 350 (L31) introduced aluminum cylinder heads with redesigned combustion chambers- these heads are significantly better flowing than any earlier cast iron SBC head and are widely used for performance upgrades on earlier 350 blocks.
For C/K truck, Suburban, Tahoe, Camaro, Corvette, Caprice, and countless other GM vehicle owners, a tested documented 350 small block is the most available and best-supported used American V8 on the market.
The 350 was produced in numerous configurations. Key variants buyers encounter:

The SBC is the most swap-compatible American V8 ever produced. It fits any vehicle that originally used any small block Chevy engine (262, 265, 267, 283, 305, 307, 327) using the same mounts and bellhousing. The 350 also swaps into thousands of custom and kit car applications due to its widespread aftermarket support.
Transmission compatibility: Turbo-Hydramatic 350 (TH350)- most common light-duty pairing | Turbo-Hydramatic 400 (TH400)- heavy-duty | 700R4 / 4L60- overdrive automatic from 1982 | Muncie 4-speed- classic performance | T56 6-speed- LT1 and late Camaro applications.

Used OEM vs Rebuilt vs Aftermarket- Which Is Right for You?
Used OEM is the right choice for a C/K truck, Suburban, Tahoe, or Caprice that needs a reliable verified replacement. Our 350s are compression tested with variant, cam type, and fuel system documented so you know exactly what you are installing.
A remanufactured unit makes sense if you want fresh tolerances with a warranty from a rebuilder. Crate 350s from GM Performance and aftermarket suppliers are widely available for performance builds. Call us to discuss options.
Mileage varies by unit. Where available from the donor vehicle we provide it. Where mileage cannot be confirmed, we disclose this before your order is placed.

Bought an LT1 350 for my Z28. Vaz specifically flagged the cam-driven water pump and told me to replace it at installation — which saved me from a future overheating situation. Compression was solid across all 8. One minor oil seep at the rear main — disclosed before shipping. Car is back on the road.
Needed a TBI 350 for my Silverado. Vaz confirmed the roller cam 1990s block and TBI fuel system before I paid. Compression came back 148 to 156 across all 8 — consistent and strong. Truck started on first crank after install. Best experience I have had buying a used engine online.
