First introduced for the 1967 model year, the Pontiac Firebird shared the F-body platform with the closely related Camaro that Chevrolet released the same year. Like the Camaro, the Pontiac Firebird's first generation spanned three years, the 1967 to 1969 models.

The 1967 Firebird rightfully gets a great deal of attention because it is the inaugural edition of the model. The 1969 Firebird receives a tremendous amount of fanfare because this was the year that Pontiac introduced the soon-to-be legendary Trans Am.

With all of that first-gen excitement, there's often little left over for that 1968 Firebird for sale at the middle of the vehicle generation. Not only does the 1968 compete with the other Firebirds for attention, it is also competing with the Camaros and Mustangs available those years.

Pontiac offered the 1968 Firebird for sale as either a convertible or a hardtop coupe, and both styles had five engine choices available to them. The standard engine that Pontiac included with the Firebird was the Standard Firebird OHC 230, a 230-cubic-inch one-barrel V6 motor that generated 175 horsepower.

The Firebird Sprint is a 230-cubic-inch four-barrel overhead-cam V6 that produces 215 horsepower. The Firebird 326 is a two-barrel V8 that offers 250 horsepower while the Firebird H.O. (High Output) 326 is a four-barrel V8 that hammers out 285 horsepower. The high performance option that Pontiac offered with the 1968 Firebird for sale was the Firebird 400, a four-barrel V8 that generates 325 horsepower, and was available with the Ram Air option.

The Firebird 400 Ram Air was 400-cubic-inch V8 motor that achieved 335 horsepower at 5300 rpm. This included a beefy valvetrain for 6000-rpm operation, a longer-duration cam, and a larger overlap. Pontiac recalibrated the Quadrajet carburetor to increase fuel flow. In addition, they made the twin hood scoops functional, and used them to duct air directly into the air cleaner. Mid-model-year, Pontiac replaced the 400 Ram Air with the 400 Ram Air II, which boosted horsepower to 340.

The 1968 Firebird for sale received a few updates to the initial '67 body. These changes include front turn lights with a wraparound style, removal of the passenger and driver side vent windows, Pontiac V-crest rear marker lights were added, and the Rally I rims were dropped as an option. Structurally, Pontiac replaced the single-leaf rear springs with multi-leaf units except on 6-cylinder models. In addition, they improved the suspension system with straddle-mounted shock absorbers, and a tire upgrade to Firestone F70 Wide Ovals on V8 models.

Pontiac made changes to the interior as well. These alterations included a larger, padded instrument panel, conical lenses and block lettering on the instrument panel, sun visors, flow-through ventilation system, lower dash adjustable round air outlets, and windshield pillar moldings. Creature comfort and safety additions included crushable armrests, lower door panel carpeting, push-button buckles, and an anti-theft ignition key warning buzzer. Other additions included stronger door hinges made of stamped steel, a larger fuse block that included eleven fuses, and a new bulkhead electrical connector.

A 1968 Firebird for sale today isn't exactly inexpensive, but it is relative to the other options of this period. If an enthusiast can find one that needs moderate to substantial work, it's a great jumping on point at approximately $5,000. Restored '68 Firebirds can range anywhere from $10,000 to $50,000, but are generally found at approximately $20,000.

Chevrolet Impala Ss to Debut in Bristol

The Chevrolet Impala SS has made its debut at the NASCAR Nextel Cup Series. And of course with its launching is the unveiling of the GM Racing’s all-new R07 small-block V-8 racing engine which provides a glimpse to the new direction in technology that America’s most popular racing series is heading.

One of the most powerful element in GM Racing’s toolbox is what the automaker calls as the CFD or the Computational Fluid Dynamics which is a mathematical simulation of the airflow around a vehicle. This new CFD technology is influencing the design of both racing and production automobiles. CFD also played an important role in GM Racing’s analysis and development of a racing version of the Impala SS which is considered as the new generation NASCAR race car that will make its debut in a competition that will be held in Bristol, Tennessee scheduled on March 25, 2007.

According to Kevin Bayless, GM Racing oval track chassis/aero program manager, “The best way to describe CFD is a wind tunnel in a computer. CFD is a simulation that predicts the aerodynamic forces acting on a vehicle using computational methods rather than physical measurements. CFD allows engineers and racing teams to evaluate the effects of aerodynamic changes quickly on a computer screen rather than in a conventional wind tunnel.”

The CFD technology was first developed for aerospace and defense usage however it migrated to the civilian sector as supercomputers which became available to manipulate complex programs. “The CFD software requires a supercomputer because the number of calculations is immense. Foe example, our aerodynamic models typically have more than 10 million discrete data points that are used to calculate the force. It really is rocket science,” explained Bayless.

"The computing time required to run CFD programs is a limitation even with a supercomputer," Bayless noted. "A team can run through more tests in a day in a wind tunnel than can be done with CFD. At this point in its development, CFD supplements the testing that's done in wind tunnels and on race tracks. We share the information that GM Racing obtains through CFD with the Chevy teams. Given the level of competition in NASCAR today, it's vital for every team.”

Although the price that is involved in this type of technology is high but the benefits of CFD are worth it. The highly advanced software makes it possible to see the invisible movement of air over the vehicle’s body.

Bayless said, "CFD allows us to visualize the flow to understand what the air is doing and where the aerodynamic forces are being generated. That's simply not possible with a model or a full-size vehicle in a wind tunnel. CFD also allows us to test aerodynamics without a physical model, which can be helpful in the early stages of a design. We can analyze and compare various alternatives before actually building a prototype vehicle."

Aside from the Impala SS becoming the new NASCAR race car of today it will be Chevrolet’s high-profile entry in Nextel Cup competition. The CFD played an important role boosting the identity of Chevy’s new on-track representative.

"Although the Car of Tomorrow is highly regulated, it's not a spec race car. As a manufacturer, Chevrolet was able to define many of the details that separate the Impala SS from our competitors' cars. The headlights, grille, portions of the hood, and the tail were areas where GM Racing was able to incorporate Impala SS styling cues and brand identity. These areas are now fixed as part of the NASCAR Impala SS package," added Bayless.

The Impala SS is entirely different from the Monte Carlo SS in terms of aerodynamics but also similar in some ways like both are equipped with quality GM auto parts like the high quality GM spark plug wires which are responsible for converting fuel into energy that powers the vehicle. For the Impala SS GM engineers have employed CFD to better understand the effects of the new body shape, front splitter, and adjustable rear wing on aerodynamic performance. "NASCAR specifications require the Impala SS to be wider and taller than the Monte Carlo SS that it is replacing, so its frontal area is larger and its aerodynamic drag is approximately 10 percent greater. Initially the Impala SS will have about 15 percent less downforce than the Monte Carlo SS, which has been highly refined over the years. The change from a spoiler to an adjustable rear wing appears to reduce turbulence in the wake of the car, so when two cars are running nose-to-tail, the less turbulent air behind the first car should alleviate some of the aerodynamic push experienced by the trailing car," explained further by Bayless.

It is also important to note that although the CFD is a powerful engineering tool it is not designed to replace the conventional wind tunnels and track testing.

What the SOLUTION about the oveartheat for 400sm chevy?

I have a small bock 400cu and i have this problem about the overheat.
With 2 electro-fan(flex-a-lite flx150, adjustable from 180°f to 240°f),the block stay in a good heat(89° c),but the 2 fanS don't stop to run and after the battery DIE IN 2HOURS.
With 1 DERALE fan transmission
With 1 Derale cooler oil
What you subject to do for stop the 2 fan when in was in the good heat
And what you subject to do about the overheat.
Sorry for my english , i speak french and tnaks for all your subject you give me

not knowing how you have these electric coolant fans wired in will make this tough. you should have a coolant temp sensor that acts as a ground source for the fans. as the coolant in the engine cools down, the coolant temp sensor should eliminate the ground from the fans and shut them down. really look at how you have this wired in.

Mustang adds muscle
The 2011 Mustang is bulked up on the outside and under the hood, giving it a ride that is more powerful but less easy-going than last year’s model. It is available at Cam Clark Ford in the Northshore Auto Mall.
