1969 Chevrolet Chevelle vs 1987 Buick GNX in Generation Gap showdown

Generation Gap generally tries to adhere to a theme for each episode, and for the final video from the Lingenfelter collection, the series might have its best idea yet - limited-production muscle cars from General Motors.
On one side you get a 1969 Chevrolet Chevelle COPO, and it's an absolute sleeper. Other than the SS wheels, this classic coupe looks practically bone stock, at least until the engine fires up. Under the hood is a 427-cubic-inch (7.0-liter) V8 making a claimed 425 horsepower and 460 pound-feet of torque. This was the sole year for the COPO package on the Chevelle, and Chevy only made about 323 of them.
The Chevelle's challenger is almost as rare and arguably just as cool. The 1987 Buick Grand National GNX looks just as mean today as when new. It eschews a traditional muscular V8 in favor of a 3.8-liter turbo V6 making a claimed 276 hp and 360 lb-ft, although that number is supposedly a bit underrated. Also, just 547 examples of the GNX version were ever built making it quite a collector's item too.

GM recalls nearly 24,000 Buick Regals for brake issue

Buick is recalling 2018-2020 model year Regals to address a software defect in the braking system that would result in a loss of power assist under certain circumstances, making the brakes difficult to operate and potentially leading to a crash. In total, 23,734 models are covered by the campaign. "In the event of a partial or full loss of vacuum-brake assist, the vehicle’s hydraulic-brake boost is designed to supply supplemental pressure to the vehicleÂ’s brake system. A software error in the electronic brake control module (EBCM) may fail to activate the hydraulic-brake boost under these conditions," GM said in its defect report to NHTSA. "If the vehicleÂ’s vacuum-power brake assist partially or fully fails, braking events may require additional stopping distance, depending on the brake pedal force applied by the driver. Increased stopping distances could increase the risk of a crash." GM says that a warning indicator will illuminate in the dash if the system completely fails, and drivers may notice an increase in brake pedal resistance. Failure will not render the brakes inoperable, but they will require more force to operate. GM has begun notifying dealers of the defect; owners should be notified starting in August.   Related video: Recalls Buick GM Safety Hatchback Wagon Sedan

Question of the Day: Best recipient for supercharged GM V6?

The good old Buick V6 engine was built from 1961 through 2008 (including a decade of production by Kaiser-Jeep) and went into way too many General Motors vehicles to list here. In 1991, the supercharged version of the 3800 was introduced, with a Roots-style Eaton blower on top, and now you can find these engines in just about every junkyard in North America. The 3800 shares a bellhousing pattern with the also-made-by-the-zillions GM 60° V6 engine, which means that it will install (with varying levels of sledgehammer clearancing and/or axle mix-and-matching) into plenty of GM vehicles that never received the 3800 from the factory. That means one thing: engine swaps! An excellent example of this is the 1992 Chevrolet Lumina APV "Dustbuster" minivan, which is a fully caged high-performance road-racing machine that features a supercharged 3800 and 5-speed manual transmission under its long, vacuum-cleaner-snout-like hood. The RaceVan, in Springfield Monorail livery, will compete this weekend at the Michigan 24 Hours of LeMons race with Autobloggers Mike Austin, David Gluckman, and Alex Kierstein at the wheel. My personal choice for supercharged 3800 power, though, has to be the Cadillac Cimarron, preferably the not-so-sought-after Cimarron d'Oro Edition. Some bashing and welding and cutting and pasting and this lightweight Cavalier sibling could have well over double its original horsepower. So, what's your blown 3800 engine-swap choice?
