In , Buick redesigned the crankshaft to a “split-pin” configuration to create an “even-firing” version. Electronic throttle control is added to all versions, as is returnless fuel injection. One quick idea was tried by Buick engineers — taking an old Fireball V6 picked up at a junkyard and installing it into a Buick Apollo. It was also the standard powerplant in the front-drive Riviera and Olds Toronado from to HP was rated at for engines Gen2 supercharger with a 2. The turbocharged Buick Regal Grand National GNX was called America’s quickest automobile, and the model continues to be collected and appreciated today.

This engine has the cylinders numbered on the left-hand bank front bank for FWD applications and on the right-hand bank, the number 1 cylinder being the furthest from the flywheel end. Dubbed the Fireball V6, it became the standard engine in the Buick Special. It was known as the Dauntless V6 and vuic a much heavier flywheel than the Buick version to damp vibrations resulting from the engine’s firing pattern.
It is also by far the most popular of the family buicc its power, smoothness, fuel efficiency, and reliability, although the stroke for the 3. Unlike thehowever, it used a batch-fire injection system rather than sequential injection, as evidenced by the lack of a cam position sensor.

In initial form, it had a bore and stroke of 3. It is effectively a lower-deck version buix thewith a smaller bore and stroke of 3. A turbocharged version was introduced as the pace car at the Indianapolisand a production turbo arrived in Buick engines Jeep engines V6 engines.
The L36 made its debut in This required that the piston connecting rods be shortened 1 in Introduced init was a lower deck version of guic 3. Final drive ratios are reduced in most applications, for better fuel economy and for improved use of the engine’s torque in the low RPM range.

It shared the same bore size as its larger sibling, but featured a smaller stroke of 2. However, AMC’s cost per unit was deemed as too high. The LC2 engine has a bore x stroke of 3. These engines should 3800 be confused as being the same, and are unique engine designs.
The engine in this configuration became known to have “off-center bore spacing”. The turbocharged Buick Regal Grand National GNX was called America’s quickest automobile, and the model continues to be collected and appreciated today. The energy crisis a decade later prompted the company to buy the design back from American Motors AMCwho had by that point bought Kaiser-Jeepand the descendants of the early continue to be the most-common GM V6 as it developed into a very durable and reliable design.
The new intake manifold greatly improved airflow. Also note that Series III engines are the base for any produced for the year and up. The muscle car era had taken hold, and GM no longer felt the need to produce a V6, considered in North America an unusual engine configuration at the time. The huic could spread to the nearby guic spark plug wire retainers on the valve cover and then to the rest of the engine compartment.
Since the cylinders center-lines were no longer centralized over the crank pin bearing journals, the connecting rods were re-designed with the big-ends offset from the piston pin ends by 1. The firing order is Eaton M62 or M90 some versions.

The L27 has a two piece, upper plenum intake and lower intake, the LN3 is all one piece. From Wikipedia, the free encyclopedia. This was the first naturally aspirated GM V-6 to feature a 4-barrel carburetor. InGM began to market the as the 3. Init received sequential fuel injection SFI and it was initially produced in two forms, the LG2 with flat lifters tappetsand the LG3 with a roller camshaft and lifters.
As with the L67, premium fuel 91 octane or higher is required, but the PCM can compensate for lower octane fuel at the cost of buiv. To date, over 25 million have been produced.
Electronic throttle control is added to all versions, as is returnless fuel injection.
