The Chevrolet cubic-inch V-8 engine debuted near the end of the muscle car era in At its peak, the was developing horsepower in the Camaro and Chevelle passenger cars. Byhowever, government-mandated smog requirements killed the muscle car as the 's horsepower rating dipped to Although the was no longer a practical powerplant for cars, it remained an option on two- and four-wheel-drive Chevy and GMC trucks, especially the 1-ton models.
Two versions of the optional were available in 1-ton Chevy trucks. The LE8 was the most common from to The L19 TBI, or throttle body injection, powered and later trucks as the second engine option. The TBI had fuel injectors in the middle of the throttle body that increased fuel efficiency, power and durability. Chevy began installing V-8s in its trucks in All s have a 4. The 1-ton trucks were equipped with a horsepower generating foot-pounds of torque.
These s with four-barrel carburetors developed horsepower and foot-pounds of torque. The trailering package came with a Turbo Hydra-matic automatic transmission, heavy-duty battery, power steering and brakes, weight-distributing hitch and trailer wiring harness. This allowed the 1-ton four-wheel-drive trucks to tow up to 4, lbs.
The advantage of these s over the LE8 versions was the electronic fuel injection and additional torque of 15 foot-pounds.
The LE8 version still served GM trucks throughalthough its horsepower rating varied from a low rating of horsepower in up to about in The standard transmission matching the LE8 on to trucks was the four-speed Muncie manual.
The Muncie four-speed manual with overdrive was available on to models. The to half- and three-quarter-ton trucks with the received the TH three-speed automatic. Only the 1-ton and larger and later Chevys got the TH three-speed automatic.

The model size was also part of the name, with indicating half a ton, for three-quarters of a ton and for one ton. Of the three trim levels -- Cheyenne, Scottsdale and Silverado -- the Silverado was the top of the line. The Chevy Silverado had four engine options: horsepower hp 5-liter or 5. Only the and models were equipped with the 7. A compact hp 4.
The C came standard with a four-speed automatic overdrive transmission. Four-wheel-drive diesels came standard with a three-speed automatic overdrive transmission.
Options for other models included three versions of a five-speed manual transmission. The Silverado can be identified by its chrome grille, which does not appear on other trims. Chrome bumpers and chrome mirrors were also a Silverado option.
The truck's interior was either brushed aluminum or wood grain. A head-liner, carpeting and an instrument panel with a full set of gauges were standard. Other options included a tilt steering wheel, power doors and windows, added sound insulation and cruise control. The Silverado could seat up to six people. Front passengers had 40 inches of headroom and nearly 42 inches of legroom. Rear passengers had The truck was designed as either the "fleetside," which had cargo box panels and a box covering the rear wheels, or the "stepside," which featured a narrow cargo box and fenders covering the rear wheels.
Both versions were offered as a regular cab, extended cab or four-door crew cab. Vehicle dimensions ranged from The Silverado had either a 25 or 35 gallon fuel tank.
It had a 16 to 18 mpg rating in the city and a 20 to 25 mpg rating on the highway, for the V-6 and smaller V-8s. The larger V-8s averaged 8 to 17 mpg in the city and 12 to 22 mpg on the highway.The new trucks were designed to meet the needs of the Chevy truck consumer, who wanted a vehicle to transport the family during the week and do light-duty hauling on weekends.
The new trucks are credited with putting Chevrolet back in front of Ford in the manufacturing of trucks that could be driven like an automobile. Chevy trucks have undergone a series of modifications since World War II.
The changes followed the evolution of the American society itself. The "C" stood for two-wheel drive trucks and the "K" for four-wheel drive vehicles. They were equipped with three- or four-speed manual transmissions and engine transmissions, cubic inch V8 or cubic inch V6 engine.
The trucks are equipped with a 6. The trucks are equipped with either a three- or a four-speed automatic transmission and two- or four-wheel drive. The four-wheel drive trucks gets 16 to 17 mpg in the city and 20 to 22 mpg on the highway.

Known for knock-out power and high revving capabilities, the Big Block V8 is respected worldwide as one of the most impressive engines of our era. As early as Chevrolets were on the road, they were developing a reputation as cars with an edge on performance. It was a 90 degree, overhead valve engine. Cadillac probably initiated the horsepower war when it introduced its new V8 in The first generation of Chevy big block engines was an important precursor to the Big Block as we recognize it today.
This was the W Series engine. The design work for an essentially new, second generation big block began inand by February ofChevrolet showed up to Daytona armed with fresh, CID big block power. The Mark III was a blip worth mentioning in that it was merely a design study stemming from the Mark II, but with wider bore centers for which GM was reticent to invest in its tooling.
Rumors swirled and significant redesigns occurred and GM was onto In model yearChevrolet released its new Big Block as most of us know it.
This engine featured an innovative valve layout in the heads that allowed it to be a highly favorable architecture for high-revs, despite the engine's notable torque and larger size. For the model year was released two Big Block variants.
One of them was the CID; a bored.
More significant for this year was the advent of the CID or 7. The engine continued to be produced for the Corvette through and some Chevy cars through The motors did begin to see detuning in the fuel-crunched 70's in addition to tangling emissions controls certainly didn't help the situation. This system continued in use throughoverlapping onto the next generation of Big Block to be released. It should be noted here that carbureted and TBI engines were produced concurrently throughthe former being delivered from GM to various its transportation and industrial buyers, including bus and watercraft companies, making these the last of the GM engines to hang on to carburetion.
In for the model year, GM released significant design changes to create the Gen. V Big Block, reflecting changes in both the engines and GM's naming conventions. Just as they had done for the Small Block inthe Big Block got a one-piece rear main seal. All main caps went exclusively to four-bolts, and the main oil galley location was moved from the oil pan rail up to the camshaft tunnel.
The valvetrain went from adjustable to non-adjustable. The use of TBI continued and because of its permanence, the now-obsolete mechanical fuel pump boss was removed from the block. Also significant was GM's move to aluminum valve covers, away from the classic stamped steel versions. This was no less true of the wonderfully persistent GM Big Blocks. As such, the Big Block was reappointed with Sequential Fuel Injection in and successfully met On Board Diagnostics II standardization and efficiency requirements and was dubbed the " Vortec", a moniker that drew from the popularity of Chevrolet's torquey 4.
Significant mechanical changes were few and included the upgrade to an aluminum front cover with an integral timing tab. Five years after its most recent and significant changes, and four years after the release of the history-changing Generation III GM Small Block V8, the Big Block would now receive its just desserts and be almost entirely redesigned and then outfitted with the same advanced control system as the Gen.
Just as revolutionary was the move to the coils-near-plugs design. The intake manifold on the Vortec is of cast aluminum, but the block and head of this engine are still made of cast iron in an industry that is otherwise moving steadfastly to aluminum alloys.
The compression ratio on this generation of engine was typically 9. Unique to the Vortec over many contemporary engines is its returnless fuel system with anti-reflux valve. Inthe 8. Additionally, the EGR valve was removed due to the advanced burn characteristics provided by the advanced PCM control system.This page is dedicated to the owners of these vehicles equipped with GM's dual point fuel injection model TBI. Many vehicles were also equipped with the 2. Although basically ignored by performance enthusiasts because of their limited performance potential, these systems perform extremely well, requiring very little maintenance of the tbi itself and is very simple in design.
They still suffer from the same mixture distribution problems as a carburetor, because of the wet manifold design, but since the mixture is very closely controlled by the ecm, the calibrated fuel requirements can be adjusted much more rapidly and with greater precision than ever could be achieved by an carburetor. Many are discovering the tbi is a cheaper alternative to the more exotic tuned port, readily available, easy to install, and the same brackets and accessories originally on their vehicles can be maintained.
One note here is that if you plan on using the tbi on your and earlier heads, the two center bolts on each side of the tbi manifold 4 total will have to be machined angle to match the earlier heads. Other than installing a electric fuel pump 15 psi maximumfuel lines and adding the proper harness and computer, the system is very simple to install and maintained.
ECM Applications: This will help you identify the different ecms so you wont get the wrong type for V8 applications. All Chevrolet TBI's use a speed density fuel calibration, using a map sensor, much like the speed density tuned ports. They also use a tps, matcts, and have a idle air control system. They also use a esc module similar to the maf tuned ports and require the proper knock sensor to mate with it. The tbi esc modules are different between the engine sizes and families.
The est distributor module sends the signal to the ecm to synchronizes the injector pulses, alternating the injectors pulses from right to left. There is also two pulses for each injector per engine revolution so the correct mixture is present when the intake valve opens. One thing about tbi, is that if you suspect a faulty injector, you can hook up a timing light and point the beam at the injector and see the spray pattern, and see whether or not it is correct or not.
The same troubleshooting techniques for a no start is the same as for tuned ports. See troubleshooting page. Also the trouble codes are the same.
As you can see from the above diagrams, compared to a carburetor, the tbi is much simpler in design. The injectors are designed to allow possible fuel vapor to rise to the top and dissipate through a channel to the return line, which the pressure is controlled through the regulator.
That way only liquid fuel which is heavier is allowed through the metering point on the injector. The regulator has four screws that hold the pressure spring against a diaphragm much like a tpi regulator.
The same principle of operation applies. There is an adjustment screw inside which is held in place with a large spot of solder. Although it is possible to raise the fuel pressure it is a harder procedure to adjust it because you would have to removed the injector assembly. Be careful in pulling a distributor to use on your TBI engine.
Note the smaller base as compared to the distributor on the right, these larger base distributors were used on some and all TBI equipped engines, such as the Caprice. They use the TBI throttle bodies which are held down with two studs for the air cleaner, and the manifolds are machined for the large base distributor they use. They will not interchange. F-body 5.InGM pushed the performance bar higher with the introduction of the Chevy V8.
Unlike the popular Chevy that was used in a wide variety of automobiles, the was used only in high performance cars like the Chevy Camaro, Corvette and Chevelle. There were 3 different variations of the that came onto the drawing board at GM during the 70s; the LS5, the LS6, and the LS7 which was designed but not produced for the general public most likely due to the massive smog restrictions that started lurking about in the early 70s.
Although the LS7 never made its way into any cars sold to the public, it was sold as a crate engine available through Chevrolet and claimed to produce around horsepower. The production models of the put out the most horsepower with the LS5 claiming horsepower and the LS6 putting out a mighty horsepower. As with many high performance engines during the muscle car wars, there were lots of rumors flying around in regards to actually how much horsepower the engines put out as opposed to what Chevrolet was reporting.
Some say that both the LS5 and LS6 motors were underrated by about 50 bhp. Of course this has never been officially proven but it could be a good argument for discussion. Unfortunately the Chevy was the right engine at the wrong time.
Uncle Sam started to tighten down on emission controls in which affected a lot of the power of the Another big blow for the was the gas crisis of which pretty much sealed the fate for the motor during this period. The last Chevelles of used the but by this point the engines had been toned down to a measly horsepower. The Corvette followed suit by the end of and also bid farewell to this once powerful engine. More good news is that today the is one of the favorites among Chevrolet performance enthusiast which means that there is an ample supply of engine parts available for the that really push the horsepower on these engines easily above the bhp mark.

The reliability and high torque made it an ideal choice for everything from light duty trucks, to SUVs and motorhomes. In its current displacement capacity, the engine debuted in It has since received several refreshes and updates through the years, allowing it to stay competitive and meet the expectations of demanding buyers.
It is also customizable, making it highly tunable for different configurations and vehicles. This 7. Horsepower output varied slightly and was application specific, but typically count on hp to hp, with torque slightly higher, coming in at lb.
The large bore and stroke made the vast majority of power available just off idle, enabling it to be a very capable towing and RV platforms. The motor is normally aspirated, meaning it does not rely on turbos or supercharging, contributing to the excellent low-rpm torque characteristics. It is fuel injected and runs on regular unleaded gas. A popular choice for recreation vehicles, the Chevy found its home in motor-homes, although it was never originally designed for that purpose.
The volume of engines produced, vast parts availability and relatively cheap cost made the transplant extremely attractive. In the engine was typically found in a long list of Chevrolet pickup trucks, Vans and SUVs, including the popular C truck series, as well as the GMC Suburban line of full-size sport utility vehicles.
Many reputable engine builders offer turnkey solutions based on the Chevy for a number of vehicles. Given the volume of engines produced based on this platform, builders offer a comprehensive warranty program. Expect at least a five-year or ,mile warranty.
