350 Chevy Crate Motor

A 350 cubic inch small block Chevy crate motor rated at approximately 450 horsepower, assembled as a turnkey roller engine with a roller camshaft and an A/C-ready accessory drive for a street and strip build.

What it is built for

This engine is aimed at builders who want a plug-and-play small block rather than a bare block to assemble themselves. The internals include a forged crankshaft and forged rods with performance pistons, paired with aluminum high-flow cylinder heads, a roller cam, and a performance intake, with either an EFI or carbureted fuel setup available.

What to check before ordering

Verify your mounts, driveline, and cooling system have the capacity for an SBC-based build before buying, since fitment is not universal across every classic or custom Chevy chassis. The listed power range runs from roughly 1,500 to 6,500 rpm, with a 2,000 stall converter recommended for drivability, and the engine is described as streetable with enough vacuum signal for accessories. Short-block, long-block, and full turnkey configurations are available, and transmission packages such as the TH350, 700R4, or 4L60E can be paired with it.
