The Chevy V8 was first introduced in and was available with four different horsepower options depending on what type of fuel delivery and performance setup was available.

The three initial carbureted models produced from up to horsepower. There was also a fuel injected model that produced horsepower. For the options stayed the same until when the horsepower was increased to bhp for the top end carbureted model known as the L76 and the fuel injected model received a boost of 15 horsepower which put it at bhp known as the L Ina 4 barrel carbureted V8 known as the L79 that produced horsepower was put into production which gave Chevy five different versions of the to use in various automobiles.

Also there were no fuel injection models of the offered in and afterwards. Buy the Chevy was only produced in three different models because of the continuing popularity of the Chevy and the introduction of the new Chevrolet V8. Chevrolet however decided for to expand the lineup of engines back to 5 different models like they had in The only big difference was now the low end came with a 2 barrel carburetor which severely lowered the horsepower for the engine.

American Motors' president, George W. Masonnegotiated a verbal agreement with Packard that the two companies would supply parts for each other when practical. This was a prelude to a possible merger of the two companies at a later date, but that never occurred.

These were supplied with Packard " Ultramatic " automatic transmissions - exclusively. Packard sent AMC some parts bids, but these were rejected as too expensive. George W. Romney ordered his engineering department to develop an in-house V8 as soon as possible.

The engineering department hired David Potter, a former Kaiser Motors engineer, to help develop the engine. Potter had previously worked on a V8 design for Kaiser, and they were able to get the all new V8 into production in less than 18 months. As such, the former quaint story of how AM's first V8 engine design came to be still persists as it echos through the hallways of US automotive history. Moore, Vice President of Automotive Research and Engineering, and through his efforts the project was carried on cooperatively by our Kenosha and Detroit Engineering Departments.

Obviously, such a division in both design and development, required the utmost in teamwork by F. Kishline, Chief Engineer, and his assistants, E. Monson and J. Voigt in Kenosha, and by R. Isbrant, Chief Design Engineer, and W.

Berry, Chief Mechanical Engineer, in Detroit. The bore size on the is cast on the top of the block near the back of the right bank cylinder head and is denoted by a '4'. The and engines do not have the bore size cast into the block. The block features a deep skirt where the casting extends below the crankshaft centerline, forming a very rigid crankcase gallery.The Chevrolet small-block engine is a series of V8 automobile engines used in normal production by the Chevrolet division of General Motors between andusing the same basic engine block.

Engineer Ed Cole is credited with leading the design for this engine. The Generation II engine is largely an improved version of the Generation I, having many interchangeable parts and dimensions.

Later generation engines have only the rod bearings, transmission-to-block bolt pattern and bore spacing in common with the Generation I and II engines. Introduced as a performance engine inthe went on to be employed in both high- and low-output variants across the entire Chevrolet product line.

Over the years, every American General Motors division except Saturn and Geo used it and its descendants in their vehicles.

Finally superseded by the Generation III LS in the and discontinued inthe engine is still made by a GM subsidiary in Mexico as a crate engine for replacement and hot rodding purposes. In all, oversmall-blocks have been built in carbureted and fuel injected forms since as of November 29, The small-block family line was honored as one of the 10 Best Engines of the 20th Century by automotive magazine Ward's AutoWorld.

In February a Wisconsin businessman reported that his Chevrolet C pickup had logged over 1 million miles without any major repairs to its small block V8 engine. Source: The Flint JournalFebruary 17, It quickly gained popularity among stock car racers, nicknamed the " Mighty Mouse ", for the then-popular cartoon character, later abbreviated to "Mouse".

The was adopted by other Chevrolets, replacing the V8s. Installed in everything from station wagons to sports cars, in commercial vehicles, and even in boats and in highly modified form airplanes, it is the most widely used small-block of all time.

Though not offered in GM vehicles sincethe series is still in production at General Motors' Toluca, Mexicoplant under the company's " Mr.

Goodwrench " brand, and is also manufactured as an industrial and marine engine by GM Powertrain under the " Vortec " name. Of the three engines in this family, two of them, the and thehave gone down in automotive history. The first of this family was theintroduced in Cole's design borrowed the valve train design scheduled to be used at the time in the Pontiac V8.

Internal GM rules at that time were that once an automotive division had introduced a technological innovation no other GM division could use it for a period of two years. The stud mounted independent ball rocker arm design patented by Pontiac engineer Clayton Leach was scheduled for introduction in the Pontiac V8. GM forced the Pontiac division to share its valvetrain design in Chevrolet's new V8 inso that in the end both engines were introduced the same year with the same valve train design.

The reason this happened is that Buick division lobbied the corporation to hold back Pontiac's release because it affected Buick's release of the new Buick V A shortcoming of the was its lack of any provision for oil filtration built into the block, instead relying on an add-on filter mounted on the thermostat housing, and that was an "option only". In spite of its novel green sand foundry construction, the '55 block's lack of adequate oil filtration leaves it typically only desirable to period collectors.

The first motors used the stock blocks. However, the overbore to these blocks resulted in thin cylinder walls. Future blocks were recast to accept the 3. This was the third U.My newest Rambler V8 is a '64 2bbl ; the center three main webs are 'windowed'. This means that there are two different block weights. I recently have come to learn from seeing pictures of '57 AMC crankshaft gallery, the early blocks had four machined and tapped mounting bosses on the outer edges of the main web X braces next to the oil pan sealing flange.

This looked to be a provision for mounting an oil sump windage baffle similar to certain mid-fifties Cadillac V8 engines, but with no pic of the baffle itself I cannot verify the speculation. I plan to weigh the 4bbl solid main block whenever the engine shows signs it needs to be rebuilt, which hasn't happened yet I use 9.

Main Bearing Journal Diameter: 2. Speaking of harmonic dampers, evidently there are two types:. For race application, the 'late' style can be lightened by mounting the unit on a lathe and trimming excess iron off the arguably heavy integral cast iron pulley portion of the hub. Doing so will decrease parasitic loss and total weight of the rotating assembly but this mod is not without trade-offs.

Do not lighten the actual inertia ring itself! See excellent article on this topic: click here for link. Don't do this mod without reading and understanding the engineering concepts expressed in the article. NOTE: There are at least two different connecting rod castings; 1 a heavier rod which is visually discerned by it's smaller weight pads -this rod's I-beam section is slightly wider at the big end 2 a lighter rod which is visually discerned by it's larger weight pads -this rod's I-beam section measures slightly more narrow where it tapers out onto the big end.

The semi-grooved aftermarket rod bearings over-extend the duration of the oil spurt feature to spray lubrication onto the sides of the crankcase gallery, where no lubrication or cooling oil is needed. Don't simply take my word for it; read about the precision engineered connecting rod oil spurt feature as described in Society of Automotive Engineer's article named "The New American Motors V8".

At higher rpm levels basically anything above rpm oil sling from the rod journals is already enough to cool and lubricate the undersides of the pistons. One final note about the mis-engineered semi-grooved rod bearings is that they weigh less, which changes the bobweight factor for precision balancing the crankshaft When I unbolted the heads, I found three other stretched bolts -very obvious.

Thread in the bolts prior to assembly to find any that might not screw in easy all the way -run a tap in there to clean it again. I like to wire brush my bolts clean, use compressed air, and put a thin line of engine oil down one side of the threads and a few lubrication 'dots' on the shoulders and washers Pistons; 3 ring conventional, flat tops, no valve notches, cast aluminum alloy, steel inserts.

Compression distance; 1.Despite the economic prosperity of the fifties and the early sixties, there had been a great many who believed that the sustainability of such financial growth was impossible, and that more challenging financial times lay ahead within the United States, and even globally. As much as General Motors tried to keep the new design of the Corvette a secret, the unveiling of the new body style would actually take place a few weeks before the car was officially unveiled to the public.

The reasoning behind delaying its introduction had been as much a financial decision as anything, though critics would actually use the delay as further opportunity to lash out at the car when it did finally arrive. Prototypes of the new car had showed an alarming tendency to lift under acceleration. This item was resolved by cutting vents in the front fenders and by increasing the spring rates.

Additionally, the low roof line restricted both driver and passenger head room. Despite all of these items, the manufacturing challenges and the subsequent delays they caused was not entirely a bad thing. The Federal government had issued the first ever safety and emissions standards, with the implementation of these standards to begin with the model year. In addition to its factory default option, the Corvette offered no less than six optional engines to consumers.

All-in-all, the new Corvette received high marks for its straight-line performance. However, there was still some criticism about how the power transfer to the rear wheels affected the drivability of the car. When it came to handling, the critics noted that while they liked the skidpad and slalom numbers that the new Corvette was producing, they did not like the way the car felt when generating them.

The new Corvette had a harsher ride than its predecessor, a fact that did not go un-noticed by the automotive press. The rear roll center was also lowered, which, when coupled with the suspension tuning, further added to the understeering issue. Elsewhere on the car, changes had been made to further help distribute weight more evenly or to improve on drivability. The Astro Ventilation system routed fresh moving air in through the front cowl, around the interior airspace, and out through grilles located in the rear deck right behind the back window.

For maximum ventilation, the rear window could also be removed. The Corvette sat lower than its predecessor had. It was also longer, wider, and heavier. The overall length of the new Corvette increased from inches to inches, and most of this was the direct result of the greatly increased overhanging nose assembly at the front of the car.

The track width increased at both the front and rear of the car, from Back in the late 60s and early 70s the big block large displacement engines received the most attention. One of Chevrolet's small block V-8 engines flew under the radar, because of its small displacement. However, with a horsepower rating of the Turbo Fire V-8 provides a lot of bang for the buck. Here we'll discuss this mighty motor and provide details about its availability.

We'll also tackle why you should consider power to weight ratio when talking about the heavy Chevy muscle cars of the late 60s. I think I made an error by not including this engine in my top five muscle car engines of all time list.

When creating the list I wanted to focus on engines capable of producing more than 1 HP per cubic inch. This represented the highest ratio of any factory assembly line engine built at that time. When compared to other powerful General Motors engines like the Pontiac Tri-powerthe produced more horsepower and weighed less while doing it. It also didn't need three carburetors to achieve these numbers. GM used the name Turbo Fire on small block V-8's starting in At first the displacement came in at By Chevrolet bored it out to cubic inches.

Popular cars like the Tri-Five Chevrolet Bel Air from through carried these Turbo Fire engines as a step up from the standard equipment six cylinders. This trend of the engine, increasing in size continued until it reached a 4 inch bore in The 5. However, when loaded up with the goodies available at the time, the engines could produce as much as HP. With that said, the most common configuration includes a single four barrel carburetor with an output of HP.

You can see an example of this engine pictured above. The end of the line of the came in Chevrolet kept the 4 inch bore, but increased the stroke to yield a total displacement of cubic inches. This is further explained below. When it comes to making a car faster there are two things you can do.The Chevrolet cubic-inch V8 originated with the small-block family of engines that first appeared in with a cubic inch powerplant.

Following with a cubic inch version that appeared inthe mighty inch small block made its debut in Although the was eventually superseded by the across the entire Chevrolet product line, the intermediate displacement was used in just about every Chevy on the market between andincluding the MalibuImpala, El CaminoChevelleChevy II and Corvette. The engine also had a relatively short 3. Even with the installation of longer aftermarket rods, the design did not need odd-shaped, compromise design pistons that later, longer stroke engines often required.

Inthe was offered in four different power ratings depending on the vehicle it was in. The base models produced through with four-barrel carburetors and a Another version manufactured through featured a four-barrel carburetor and the same compression ratio, but produced horsepower and foot pounds of torque. Although most examples of the were carbureted, some of the early Corvettes came equipped with fuel injection and made more horsepower.

Thanks to Rochester fuel-injection and 1. In andthe Corvettes used the same heads with even larger intake valves 2. The fuel injection, big valves and a 1-to compression ratio allowed the Corvettes to run the quarter mile in just under 15 seconds and zero-to 60 times were recorded at under 6 seconds.

Factory interest and development of the began to slow by when Chevrolet introduced the big-block and Inthe factory dropped the compression ratio of the to a mild 8. The last iteration of the appeared in with a two-barrel carburetor and a 9-to-1 compression ratio that produced horsepower and foot pounds of torque, but by then another Chevrolet small-block had already appeared on the market and had begun stealing what thunder the had left. Prior to the appearance of the larger and ultimately more versatile cubic-inch small-block Chevrolet inthe compact was the most powerful and most efficient small-block engine Chevrolet had ever produced.

That the is still utilized by many classic Chevrolet fans today is testament to its lasting legacy of power and efficiency. We will keep you up to date on the latest accessories and parts in the industry.
