Chevrolet has released a deluge of information about the 2014 Corvette’s fifth-generation small block V8 - the LT1. Despite displacing the same 6.2 liters as the outgoing LS3 mill, the LT1 is 99.9 percent new and packed with significantly more power and technology than its predecessor.

The new small block churns out 450 horsepower at 6000 rpm and 450 lb-ft of torque at 4000 rpm, improvements of 20 ponies and 26 lb-ft over the LS3. Chevrolet says that output is enough to empower the C7 Corvette to sprint from zero-to-60 mph in under 4.0 seconds, and with over 400 lb-ft of twist on tap between 2,000 and 4,000 rpm, the LT1 also provides plenty of mid-range output.

Though it retains the tried-and-true pushrod configuration, the LT1 features direct-injection, variable valve timing and a fairly high 11.5:1 compression ratio. A dry sump oil system will be an optional extra in place of a standard wet sump unit.

Also part of the LT1 package is a cylinder deactivation system that saves fuel by effectively turning the 6.2-liter V8 into a 3.1-liter V4. Chevrolet says the system will help the LT1 better the less-powerful LS3's 26-mpg highway rating.


Wonder when someone will slap one in a GTM

Wow. I was expecting those type of numbers out of a 5 point something liter motor. Up until now, I swore everyone was talking about a noticeably downsized V8.

I have had an order in for the heads for quite some time with my engine builder, but I may have to go with an entirely new engine. :(

Word is up to a 15% increase in fuel mileage. That is important to endurance racers. I was really looking to mate the DI heads on an LSX bottom end and attempt to get around 1000HP out of it. I already have the only aftermarket DFI computer that I know of to control it. I have very much been awaiting this release of the production of the 2013-2014 Vette DI V8. We shall see.

I thought it was to be a smaller displacement also. Well based on this, the speculation around the new Silverado motor can be put to bed. I would really like to see a twin turbo V6 go in one of them. Guess well just have to wait for the C8
