Chevy's LS motors are nigh-on legendary at this point. Compact and versatile despite their meaty power and torque, they're the perfect small-block engine to throw in just about any chassis if you want to turn it into a roaring muscle machine.

There are no less than 13 LS donks in the catalog to choose from at this point, but the new LS427/570 is the biggest and baddest of them all. Developed and enhanced from the 505-horsepower LS7 engine, the new motor is a whopping 427 ci (7-liter) cast aluminum V8, naturally aspirated and tuned to produce 570 hp and 540 lb-ft (732 Nm) of torque, with a snarling 7,000-rpm redline.

That is of course before the crazed tuners of the world start hitting this thing with turbos and blowers; with the appropriate pistons, rods and forced induction this block will surely be capable of more than a thousand horses.

Chevy has made the new king LS motor easier to install, by using a new wet sump oil system – the LS7's dry sump required tuners to fit their own oil tank and lines. The 14-inch, 68-tooth flywheel is straight off the Camaro Z/28 and ready for a manual gearbox.

This is not, Chevy says, intended as a street engine. It's not emissions-legal for road use, and it's recommended as a race motor, as much as that's likely to stop anyone.

I used to be impressed by this kind of thing, until Tesla...

I'm with Guz (but was always a Ford man as a mechanic). I'm much more impressed with electric torque and a silent vehicle.

I agree with Guz too, but don't know whether to be happy or sad. Tesla has kind of ruined it for me. When can we buy a Tesla crate motor/battery package?

While I am sure that electric cars are the future, I have to wonder why my 6,2 liter 540hp Corvette gets almost as good highway mpg as my 2.5 liter 178hp Camry which weighs the same. Something just doesn't seem right. It seems like ICE engines could still be dramatically improved. I remember back in the 1960s when someone came out with a Freon powered motor that was attached in parallel with the gas engine. The Freon engine used the waste engine and exhaust heat to deliver more power and efficiency out of every gallon of fossil fuel. I read an article a couple years ago that claimed that if there was one electric car on every city block, the electric demand would outstrip the total current grid capacity. I don't know where they got their numbers but I do know that a hot summer day can result in brown outs just from increased air conditioning use. Throw in a few million electric powered cars and trucks and see how many more windmills and solar panels it will take.
