STEP RIGHT UP and see the AMAZING Z06 engine assemble itself in virtual reality!!! AND see the Monster-Motor LS9 built in just 2-minutes and 13-seconds!!!

To see the BIG version, click the above image.

If you’ve been following us here at CorvetteReport.com you will have noticed that WE LIKE ENGINES here. Being a muscle car, sports car, and drag racing historian, I’m well versed on the great engines of the past. It took a long time for aluminum to work its way into American performance engines. All the way back in 1957 Zora Arkus-Duntov was proposing an all-aluminum engine for the Corvette. It just seemed like an excruciatingly slow process. We got aluminum intake manifolds, water pumps, bell housings, and transmission cases by the early ‘60s, aluminum heads from ‘67 to ‘69, and one minimal attempt at an all-aluminum big-block in ‘69 with the 427 ZL-1. While the ZL-1 was available as a separate purchase for a long time, we had to wait until ‘97 for the arrival of the all-aluminum LS1. Since then, we have been treated to the LS6, LS2, LS7, LS3, and the 638-HP monster LS9.

Machined steel is cool, but there’s something unique about machined aluminum. The LS7 animation is quirky-cool. Not only does the engine float in a blue sky, the crankshaft and entire assembly is animated as the parts come together on their own, the entire engine horizontally rotates. It’s very cool.

The second video is a speeded up assembly of a real LS9 engine at the GM Performance Build Center, in Wixom, Michigan. The new Corvette Engine Build Experience option lets ZR1 and Z06 buyers watch and help build their own engine. How cool is that?! The video is kind of an “over the shoulder” view of the experience – but, REALLY FAST! Continue reading “Vette Videos: Virtual LS7 Engine Build & High-Speed ZR1 Build” →

Engine History Made! 100,000,000 Small-Block Chevy Engines, and Counting!

Chevrolet announces the 100-millionth Small-Block Chevy engine to be built and installed in a ’12 Corvette in Fall 2011

Former chief of Chevrolet engineering and president of General Motors, Ed Cole.

This week Chevrolet announced that the 100-millionth Small-block Chevy engine will be built sometime in Fall 2011 and will most likely be installed in a 2012 Corvette! So three cheers to Chevrolet.

Hip, hip, HOORAY!
Hip, hip, HOORAY!
Hip, hip, HOORAY!

Although the small-block Chevy engine was designed to be an efficient passenger car engine, the design’s simplicity and durability has been providing Chevy fans with some of the fiercest engines ever. SBCs have powered just about every kind of race car from Indy and Le Mans, to drag strips and dirt tracks all over America.

Which SBC will be the magic 100 millionth engine has not yet been announced. It could be the mighty 430-horsepower LS3 engine used as the base engine for the Corvette, or possibly the most powerful production engine ever built in Detroit history, the 638-horsepower supercharged LS9 that powers the C6 ZR1 Corvette rocket ship. I’m sure that Chevrolet will make a BIG media splash about this car.

Enjoy our Small-Block Chevy engine gallery.

The man credited with designing and developing the SBC was former General Motors president, Ed Cole. As a youngster Cole liked to tinker with radio sets and was briefly a field rep for a tractor manufacturer before enrolling in the General Motors Institute where he got his degree in engineering. In 1949, along with GM’s Harry Barr, Cole developed the acclaimed 1949 Cadillac OHV V8 engine. By 1952 Cole was promoted to chief of engineering for Chevrolet. His first major project was the design and development of the replacement for Chevrolet’s tired, old, Stovebolt-Six engine. The finished engine was essentially a simplified, smaller version of the Cadillac OHV engine he’s helped design in ‘49.

When nested between the front fenders of the new ‘55 Chevy, the 265-cubic-inch, 162-horsepower engine looked, well, tiny. It probably only took a few weeks for hot rodders to realize that there was a ton of red meat in the little lightweight engine. The new small-block Chevy quickly developed the nick name “Mouse Motor.” Within a few years, the new SBC completely changed hot rodding and racing. It was, “good-bye Flathead Ford” and “Hello Small-Block Chevy.” Continue reading “Engine History Made! 100,000,000 Small-Block Chevy Engines, and Counting!” →

The Art of the C4 ZR-1 LT-5 Corvette Engine

Corvette Engines as Art Objects


Too bad this wasn’t a 283 Fuelie!

Everything has a beginning, right. For me, it goes back to 1965 when my Dad bought me “The Visible V8” model kit. What a wonderful way for young boys to understand the basic operational principals of an internal combustion engine. If you carefully put the parts together and didn’t get glue in places you shouldn’t and wired everything right, your got to see the pistons go up and down, rocker arms actuate, the fan spin, the camshaft rotate, AND the red grain-of-wheat lightbulb spark plugs light up at top-dead-center. Of course, it sounded all “WHEEEEEE” Because the battery-opperated starter motor was driving everything. “Sorry kids! No VROOM! VROOM!”


LT-5 art prints available HERE.

But, it was a lot of fun and started my lifelong passion for engines. But engines didn’t become “art” for my until I got into drag racing and those wonderful supercharged hemi engines. And the first Corvette engine that wowed me was the 1967 L71 427/435 big-block. While 3-deuces Continue reading “The Art of the C4 ZR-1 LT-5 Corvette Engine” →

Corvette Odd-Ball: SHOCKING! Naked C1 Fuelie Corvette!

An Expose-look under the pretty fiberglass of a C1 Fuelie Corvette!

Now here’s something you don’t see every day. A C1 Corvette without a body and interior. Just the engine, drive train, suspension, wheels, tires, and the steering wheel. And not just any C1 Corvette, a Fuelie Corvette!

Up front I must apologize because when I was at the April 2011 Strictly Corvettes and American Muscle Cars Show at the Atlantic City Convention Center, I was also a vendor and had little time to get away from my booth. So I kind of zoomed through and took pictures of what looked interesting. The chassis-only display really caught my eye. You just don’t see this every day. I did the same thing with Kevin McKay’s drivable 1969 427 L-88 drivable chassis-only, Corvette. (see links below) Continue reading “Corvette Odd-Ball: SHOCKING! Naked C1 Fuelie Corvette!” →

427 ZL-1 John Greenwood & A NHRA Top Fuel Record Holder Chevy Top Fueler!

Aluminum engines are so common today that no one even notices. But back in the ‘50s and ‘60s, aluminum engine components were considered trick hardware. All-aluminum high-performance engines were only found in exotic European cars. Having learned his engineering and racing craft in Europe, Zora Arkus Duntov first proposed an all-aluminum engine as part of the 1957 Q-Corvette proposal. Also included in the proposal was an aluminum transaxle. This was actually part of a larger plan called the Q-Chevrolets for 1960. Chevrolet chief engineer, Ed Cole, envisioned the entire line of Chevrolet cars equipped with the transmission mated to the rear axle as a way of vastly improving the interior space of every Chevy.

The plan was eventually scrapped for cost reasons, but Duntov was definitely keyed in on the idea of adding aluminum engine and drive train components into his Corvettes as a way to lighten the car. Through the ‘60s, aluminum parts slowly crept into the Corvette. But it wasn’t until the introduction of the ‘67 L-88 that the automotive press and fans really took notice of the lightweight hardware.

 


One of Duntov’s favorite playgrounds – the GM test track!

But when Zora and his team unleashed the all-aluminum ZL-1, jaws dropped and eyes popped! The thought of a solid-lifter, 12.5:1 compression, big carb 427 that weighed as much as a small-block was just OUT’A SIGHT! FAR-OUT! GROOVY, MAN!

Hot Rod Magazine splashed the all-aluminum ZL-1 on the cover and caught a lot of heat for spinning the fan on an engine that was obviously not running or attached to anything. The yellow headers or ANY headers for that matter were NOT part of the ZL-1 package. Unfortunately for fans of lightweight Corvettes, the ZL-1 was for all intent and purposes a teaser option. Yes, the ZL-1 was an official option costing $4,718, PLUS $1,032 for the L-88, on top of the $4,781 base price of the ‘69 Vette. Only three ZL-1’s were “officially” built and all are accounted for. However, there may have been 10 or so ZL-1 Corvettes built as demo cars. CARS Magazine editor, Marty Schorr was one of the fortunate few that got to drive a ZL-1 ‘69 Corvette and it was NOT one of the three surviving ZL-1 Corvettes.

Fortunately, for racers, such as John Greenwood, ZL-1 engines could be purchased as crate engines. While Greenwood wasn’t the only Corvette racer to use a ZL-1, his stars and stripes, BF Goodrich-sponsored Corvette became a legend. One ZL-1 engine even made its way into Jim Butcher’s Top Fuel dragster and actually held the NHRA elapsed-time national record for a few week in 1973. The all-aluminum ZL-1 gave Butcher a 500-pound advantage over the cast iron Hemi dragsters of the day!

It’s too bad that it would take 28-years before a production Corvette would finally be powered by an all-aluminum engine. The LS1 engine powered the ‘01 C5-R Corvette to Corvette’s first big class win at le Mans. Today’s all-aluminum, 638-horsepower LS9 engine is the most powerful production car engine ever produced in Detroit’s history and is ONLY available in a Corvette!

Would a Fuelie ZL-1 work for ya? YIKES!!!

NHRA Gatornationals – Hemi fans COULD NOT BELIEVE that Jim Bucher’s little Chevy Top Fueler set the NHRA Top Fuel ET National Record with a 6.09 ET! Too bad the car didn’t dip into the 5’s!

The POWER of the Corvette

Published on by Scott

From the Blue-Flame Six to the Mighty LS9,

a Salute to Corvette Engines

Check out the SLIDE SHOW at the bottom of this post!!!

If you are new to the Corvette hobby, it’s hard to realize that 57 years ago the car began as a 150-HP beauty queen, made from a new and exotic material called “fiberglass,” available in any color, so long as it was white. As soon as Duntov could get his “magic hands” on the first small-block Chevy, the party began. Dual quads showed up right away and before we knew it, in ‘57 we had a fuel-injected Corvette. Take that! European exotics! F.I. is common today, but back then, wow, that was American-style autoexotic.

Corvette engines all have a story – small-blocks, big-blocks, the new LS series engines. Continue reading “The POWER of the Corvette” →

Kevin Mackay’s Drivable, See-Thru, ’69 L-88 Corvette

Published on by Scott

Drivable Corvette Art

I consider Kevin Mackay to be a “Corvette artist.” Some of us use paint, markers, pen & ink, etc. You know, “artsey” stuff. Some artists work in other mediums – such as metal and fiberglass. Kevin Mackay’s “Corvette Repair” doesn’t just perform world-class restoration work on classic C1, C2, and C3 Corvette race cars and regular Corvettes, Kevin is also a mechanical, educational artist.

It’s always a pleasure to see Kevin at the shows. Last weekend we were vendors at the Strictly Corvettes and American Muscle Cars Show in Atlantic City. When you love Vettes, what’s there to not like about a Corvette show? We saw lots of smiles and had many interesting conversations. Kevin Mackay was on hand for the third year in a row with a delightful stable of customer cars, as well as several of his beauties.

1965 396 L78 Corvette – The First Big-Block Corvette

Published on by Scott

The Latest Installment in VETTE Magazine’s “Illustrated Corvette Series” by K. Scott Teeters

Were it not for NASCAR Chevys trailing behind nearly everyone in the early ’60s, there may never have been a big-block Corvette. Fuelie Corvettes were doing very sell in SCCA sports car racing, but the NASCAR Chevys where in trouble. While GM was officially not racing in the late ’50s and early ’60s, Duntov and a few other Chevy engineers kept select Chevy racers supplied heavy-duty specialty parts for field testing. Engineers tried to help with the Z11 Impala option that made a 427 out of the 409 truck motor. The car performed well as a drag racer, but wasn’t a competitive stock car racer.

In the Summer of ’62, Chevy engineer Dick Keinath was tasked to design the next generation big-block Chevy engine. Since the 348/409 was called the Mark I, the new engine was named, Mark II. The new block was based on the thick bottom end design of the 348/409 for low end strength, and new free-breathing heads. Continue reading “1965 396 L78 Corvette – The First Big-Block Corvette” →

Stunning Die-Cast Corvette Engine Models

Corvette Engines As Miniature Automotive “Art”

Note the quarter on the display base for scale.

Modern high-performance engines are just amazing machines. A quick look at the most powerful production engine to ever come out of Detroit is the supercharged LS9 ZR1 Corvette engine. This 376-cubic-inch engine has a Net horsepower rating of 638-HP. Measured in the old “gross” power rating system and the number would be easily be in the low 700-HP range. The ZR1 and it’s little brother the 505-HP Z06 can easily smoke ANYTHING from the old glory days of the stump puller muscle car era and get double the gas mileage to boot!

But this isn’t about numbers, it’s about aesthetics. Take the plastic or carbon fiber covers off on any LS-powered Corvette and you’re greeting with a maze of complicated hardware. I guess I’m “old school,” but I enjoy looking at old, pre-smog control device muscle car and racing engines. The simplicity of those old mills was oftentimes “art.” Continue reading “Stunning Die-Cast Corvette Engine Models” →

1957 Fuel-Injected Corvette: Detroit’s First Fuelie

Published on by Scott

An American Auto Exotic – ‘50s Style!

1957 Fuel-Injected Corvette – An American Classic

Today, fuel-injection is no big deal. But lets roll back the clock at least 60 years. The first successful mechanical application of gasoline F-I was in the V-12 engines used in the WW II Messerschmitt Bf 109 airplane. After the war, Mercedes-Benz used direct-injection in their W. 196 Grand Prix racer, the 300 SLR racing car, and 300 SL sports car. Mercedes-Benz used a “timed direct-port injection” that was very efficient, but complex and expensive.

In the early ‘50s, the world of sports cars was pioneered by European car makers. Fortunately for us, one of the most powerful and influential designers in Detroit had the sports car bug. GM’s Harley Earl envisioned an American sports car and most of us are familiar with the beauty queen turned street brawler Corvette story. As fate would have it, Chevrolet chief engineer, Ed Cole hired another key player, a man with sports car engineering and racing experience – Zora Arkus-Duntov. Fortunately, GM had an engineer that understood the complexities of F-I, one John Dolza from the Rochester Division.

Corvette Oddball: Did Chevy Ever Build a Drag Racing Corvette?

Published on by Scott2 Comments

Dateline: 8.10.2010
Answer: Not for actual drag racing competition. (now THAT would have been interesting) But they did build a dragster Vette, just to show off a little.

69 Corvette Engineering Study
69 454 ZL-1 Corvette Drag Racing Engineering Study

(SPECIAL TREAT AT THE BOTTOM OF THIS POST!)

The introduction of the four wheel, independent suspension in the ’63 Sting Ray was a major breakthrough for road racers, but left drag racers with tons of rear suspension broken parts. Let’s face it, the production independent rear suspension was never designed for those brutal drag racing starts. Corvette engines, small and big-blocks have never had a problem producing lots of power. Too much power for the Corvette’s rear suspension.

Although there were a few successful drag racing Corvettes that included Bo Laws, Astoria-Chas, and Bernie Agman, most drag racers used the solid-axle Camaros, Novas, and C1 Corvettes.

At the ’70 press introduction in the Summer of ’69, Chevrolet had a specially prepared ’69 Corvette engineering design study set up for drag racing.  Actually, it was the same car used the previous year to show off the ’69 ZL-1 engine. Duntov and his crew wanted to show off the awesome power potential of an even bigger ZL-1.

Chevrolet’s Hib Hufstader and Tom Langdon built the flaming orange, drag race prepared Corvette with a 454 cubic-inch version of the all-aluminum ZL-1 with a modified Turbo Hydra-Matic automatic, open 180-degree headers, and racing slicks for the press to “play with.”The menacing-looking Monaco Orange ZL1 was a press darling. Duntov enjoyed keeping the automotive press happy. Continue reading “Corvette Oddball: Did Chevy Ever Build a Drag Racing Corvette?” →
