More than merely a conversion of the stock LS7 engine to E85 capability, Leno’s alternative-fuel supercar is powered by a custom, 8.2L (500-cubic-inch) all-aluminum small-block V-8 that pumps out approximately 600 horsepower and 585 lb.-ft. of torque.
“The C6RS is the result of an idea we hatched to prove that high-performance cars and alternative fuel technology weren’t diametrically opposed concepts,” said Leno. “I love the idea of having 600 horsepower at my disposal, but using a homegrown alternative to gasoline.”
The engine is built around a custom aluminum cylinder block that was CNC-milled from a single block of billet aluminum. And while the cylinder heads, intake system and dry-sump oiling system are stock LS7 components, the engine - which has larger bore and stroke dimensions than the 7.0L (427-cubic-inch) LS7 - uses a one-off reciprocating assembly, including a forged steel crankshaft, forged rods and forged pistons. Katech Engines, the company that builds engines for the Corvette C6.R racing program, developed the engine.
I wonder what kind of mpg he gets…
I’ll make sure I take pics of it tomorrow at SEMA 
thats pretty cool.
I help design Ethanol plants, always cool when things like this come out.
Thats a CORNey idea aahahahaahhah

8.2L V8? weird.

why is that weird, the is no replacement for displacement

wow, just keep the bad jokes to yourself
Not to impressed with the #'s but it is neat. Gas mileage has got to suck. E85 a/f ratios are a lot richer than reg gas.

Hey, shove it in your CORNhole
I think its a great idea… It seems that if anyone is going to pay for this it would be Jay Lenno, your probably going to need all that displacement to pull that much power and torque out of that energy efficient of a motor.
yummy, i always loved corn…

its not weird…just not normal…thats a big V8…its likesaying …a 3.8L 4cylinder…just sounds weird
its three liters smaller than the merlin block

looks like fun, I wonder how the power curve is… :gotme:

For each mile you drive it the cost of meat, milk and eggs goes up 10 cents.
Yay ethanol!
Leno looks like he would drive a Vette :lol:…sounds like having an alternative to gas isn’t so bad these days
nice ride… but you’d think jay leno being the car guy he is would think a bit smarter than the average politician
E85 Corvette - what a stupid ‘green’ ploy for publicity
So how do they get 500 ci out of a small block? With 4.4" bore centers the typical max bore is 4.155" afaik. With 4.155" you’d need a stroke of 4.6" to get 500 ci. I think you’d need a taller than stock block to pull that off.
