SMALL-BLOCK ENGINES

Small-block and big-block Chevy engines differ primarily in physical size, weight, and bore spacing—with small-blocks offering a lighter, faster-revving setup, and big-blocks usually delivering massive cubic inch displacement and low-end torque, although there are some exceptions to this norm.

A typical small-block engine has a displacement between 262 and 400 cubic inches (about 4.3 to 6.6 liters).

These are popular because they offer a rare mix of compact size, low cost, massive aftermarket support, and bulletproof reliability. They deliver high horsepower out of the box and fit easily into almost any hot rod, classic car, or project vehicle. 

Yes, 350 is considered a small-block. Small-blocks have a narrower distance between cylinder bores and smaller outer dimensions as compared to the geometry of Big-Block.

This can be accomplished through any of the participating Chevrolet Performance Parts Dealers.

Chevrolet Performance validates their crate engines using strict factory-assembly controls, specialized cold-testing, air-leak pressure checks, compression evaluations, and rigorous research-and-development, and dynamometer durability testing for each region that holds possible sales.

A Chevrolet Performance crate engine gives you a brand-new factory type build, zero hidden wear, a solid 50.000-mile warranty, and predictable power. A junkyard pull costs less upfront, but it carries unknown risks, hidden damage and usually requires a full rebuild, if you can still find them in junkyards.

The CPP Small Block Crate engine is offered in multiple build stages to suit a range of performance and installation needs. Customers can select from a partial short block, base engine, deluxe assembly, or complete Turn-Key package. With each successive stage, the engine is supplied with an increasing number of pre-installed components and accessories, simplifying integration and reducing the amount of additional parts and assembly required by the end user.
