RIDING LARGE

Who Says Big Means Slow? The 425hp 427 Bel Air Was Anything But

Eyes wide open, with faces up against the glass, kids on a passing school bus wondered what it could be. Amazed by the size of this land yacht, some must have wondered what it was like to pilot such a gas-guzzler, while a few couldn’t help but smile at the resounding roar of the mighty L72 427 underneath it all.

From behind the wheel, Adam Presley’s driving experience is much different from that of onlookers, especially what these youngsters might have perceived, as this relatively light behemoth is only slightly longer in wheelbase than a Chevelle. While weighing well short of 2 tons, the two-door moves right along, too, easily torching the tires through first gear and into second at will. It’s about that time that the cacophony beneath the hood drowns out the exhaust note, and within 13 seconds, a quarter mile has slipped by.

For the kids among us who aren’t sure, this is one of a handful of remaining ’69 Chevrolet Bel Airs fitted with the big-block 427 pumping out 425 hp. While fewer than 550 of these cars were built originally, and even fewer with the Muncie M21 four-speed, it’s lucky any of these cars survived their original purpose—drag racing. But luckily there are still a few around, and fortunately, Presley was able to restore this one for Danny Mullis, a quiet enthusiast who prefers giving credit to the people who brought this car together, rather than to himself for having the interest to build the car and extend this bygone era that helped mold Chevy’s performance heritage.

Ironically, Mullis initially didn’t even like the car, but as time passed and the patina returned to this mighty Bel Air, he began to better appreciate its rare and unique appeal. Everyone loves hardtops and convertible Impalas, but when it comes to rare, this is a super sleeper if there ever was one. The combination was potent and had them covered on several levels, not the least of which was class-winning performance. Without the burden of air conditioning, a radio and speakers, power steering and other accessories that added to the car’s total weight, this car is able to apply its power with surprising effectiveness.

The interior is almost Spartan in its simplicity. The black carpet and the black vinyl covering the huge bench seats are about the only deluxe items; rubber mats were standard, although, as it turned out, they weighed more than carpet. Remove the radio and other amenities and there’s no question of the intent here—what you have is a “stripper” Bel Air racecar.

Not just any 427, the L79 was the big dog of its day, fitted with a forged crank, special rods with 7/16-inch bolts, high-compression pistons and a mechanical lifter camshaft. The bottom side of the cylinder heads feature 2.19-inch intake and 1.88-inch exhaust valves, while on top, an aluminum high-rise intake manifold disperses a mixture supplied by Holley’s 780cfm 3310. Other features, such as the deep-groove pulleys and high-volume oil pump, ensure this monster stays in check, even as the motor nears its scary limits. To get a good handle on the heavy-duty Muncie gearbox, a Saginaw shifter rises from the floor just ahead of another rare aspect of this Bel Air, a bench seat wide enough to fit a school bus. Still, the thought of going through the gears with five other passengers onboard is not what this car was about, however intimidating that might be for the hangers-on, as this Chevy will cover the quarter mile fully loaded almost as rapidly as it will go the distance with a driver only. Again, don’t let the size of this old “post” car fool you—this is rapid transit by any measure.

The chassis retains all of its original hardware save for the original rubber bushings, which have been replaced with heavier-duty versions to maintain better suspension geometry and to smooth the ride. Even though drum brakes have been retained all around, these happen to be power-assisted and will actually pull this car down from speed with great ease, as long as it’s not raining. It’s also interesting to note that the same rear sway bar that is used under some ’69 Chevelles is tucked under the back of this Bel Air. The 12-bolt rear axle supports 3.73 gearing with Positraction, which, considering the limits of the relatively narrow F70-15 Firestone Wide Oval tires, begs for more traction.

Aside from the sizable seating arrangements and a brace of seat belts, everything about the interior is austere, as it was intended from the start to serve function and reduce cost, even though the optional 427 engine priced this car much higher than other big cars in the Chevy lineup back then. The audio system was reduced to a radio-delete panel, and there’s little in the way of flashy trim or detailing. Of course, there’s a post separating the doors from the rear side windows, and while this was certainly less appealing to most back then, it is just what racing enthusiasts looked for in the day. What’s different today is that cars that were less favored, and therefore limited in production, are far more treasured models today.

Unlike cars built to win show trophies, the original look of the engine compartment was retained. While you can’t tell from the outside, the internals enable the 427 to scream to redline. A forged crank and rods, big valve heads and a capable intake system were specifically chosen to make 425 factory horsepower. Truth is, it made much more.

Fortunately, this ’69 Bel Air 427 is as good as new, and surprisingly in these times of trailer queens and tow vehicles, it is driven on a regular basis, but not by the owner. Instead, Mullis prefers to get the builder behind the wheel. Needless to say, this is a great opportunity for Presley, as he’s spent a great deal of time returning this car to its original state, and then some. He expressed his thanks for this rare and much-appreciated opportunity by saying, “Even though it belongs to Mullis, I get to drive it and clean it without having to lay out the considerable cash for an amazing ride like this.” Not bad for a car that continues to attract some very impressive bids.

While it’s highly unlikely the kids on that bus knew what they were looking at, this big Bel Air does have a way of bringing out the kid in us, and that goes double for anyone with a love of cars that were different. While it may use up more space with its far larger footprint, and it certainly is made of more steel than two modern hybrids and is capable of burning more fuel than five or six of them over a given distance, this stripped-down, high-performance Chevy reminds us of another time when the government and the gas companies were less interested in manipulating our lives. And, while we’ll never see the likes of this car again, those that remain are part of the wonderment of it all and help drive the love affair we all share for yesterday’s performance Chevy, and with no flash at all— just a big car with brute power.
