The small-block engine is a mechanical representation of shouting “Power to the people!” out loud and today General Motors will say this for the 100th millionth time.
Yes, 56 years after the first V8 small-block engine was produced by Chevrolet, the ever-present powerplant has reached this production milestone. You’ll find this mill in Chevrolet, GMC and Cadillac cars in the US, as well as in Vauxhalls in the UK and Holdens in Australia.
The milestone engine is a mighty 638 hp supercharged LS9, the heart of the Corvette ZR-1, which is hand-built at the GM Performance Build Center in Detroit. This is the fourth generation of the small-block.
How was this figure achieved? Well, GM also counts updated versions of the original first-generation engine (still in production for industrial applications), Chevy crate engines, as well as the 4.3-liter V7 unit in certain Chevrolet and GMC full-size trucks and vans, which is based on the small-block architecture.
