An affordable icon 

The 350/290 Base is an economy-minded alternative to rebuilding Gen 0-type 265-400-cubic-inch Small-Block engines. It’s assembled with all-new, premium components, including a brand-new block with four-bolt main caps—a strength-enhancing feature most original and core 350 engines don’t have.

Powerful & durable 

Like all Chevrolet Performance Small-Block crate engines, it’s built with a cast-iron block. It’s got four-bolt main caps and it’s filled with a tough rotating assembly, featuring aluminum pistons delivering an 8.0:1 compression ratio.
