Does Chevy's Small-Block V8 Have a Future? GM Thinks So

In an age known for its electric vehicles, hybrid drivetrains, clean diesels and alternative fuels, you might not think there's a place in the world for a pushrod V8 with architecture dating back to the 1950s.

GM disagrees though, and is currently making a case for continuing the lineage of one of the world's great engines. GM is soon investing $400 million at its plant in Tonawanda, NY and $235 million at the St. Catherines plant for small-block production.

As die-hard Chevy fans will tell you, the small block has plenty of plus points. It's reliable, strong, and offers great low-down torque which provides not only good-to-staggering performance depending on the variant, but also the potential for impressive economy when driven sedately.

It's also very compact thanks to the pushrod, overhead-valve design, which means it can still be fit under the hood of low-slung sports cars like the Corvette. This is one of the reasons GM is keen to keep the small-block and retain the same architecture, only with updated technology such as gasoline direct-injection.

The design also makes incorporating fuel-saving tech such as cylinder deactivation quite cost-effective, and with the modern aluminum block variants it's also incredibly light weight for its potential output.

The 90-degree small-block was first seen in the 1955 Chevrolet Corvette, making 195 horsepower. The ultimate modern variant is the Eaton supercharged, 638-horsepower and 604 pounds-feet unit fitted to the Corvette ZR1. At some point this year, GM will build its 100 millionth small block.

That's quite a history, and V8 fans the world over will be looking forward to many more variants of the small-block in the future. GM's investment will help create and protect 1,600 jobs and help protect an American icon, too.

  1. Absolutely the SBC has a future. With so many people both in and out of the NMCA drag racing scene running the Small Block Chevy, yes- not to mention all the people who swap the venerable SBC into other vehicles. The SBC is a mainstay of engineering and reliability. It may be over 50 years old, but given the huge advances and updates that have been made since -- they've taken a good thing and brought it to the next level, I mean- it'll do 30mpg with 5.7L of displacement with a 6-speed. I post about these motors daily here: http://www.facebook.com/NMCADigital - Check it out to see what the present holds for the SBC. - Nitro Nick
