First released as an up-level trim option during the 1965 model year run on Impala 4-door hardtops, the Caprice model was the most luxurious Chevrolet offered. For 1966, Caprice became a full-fledged series and was extended to 2 and 3-seat station wagon models plus as a 2-door “Custom Coupe,” which featured a brand-new and distinctive formal roofline.

The 1966 Chevrolet Caprice Custom Coupe had a look all its own and set the standard for years to come with its squared-off roof design for 2-door hardtop models. “Caprice—elegant the Chevrolet way” was how this new these top-of-the-line vehicles were promoted.

427

Two different 427s offered during the 1966 model year run, the L36 plus a L72 425-hp version that featured a stronger four-bolt main block, stronger connecting rods and caps, special camshaft with solid lifters, higher compression (11.0:1 as compared to 10.25:1 for the L36) and an aluminum intake manifold with Holley 4-bbl. carburetor. While the L72 made more 35 more horsepower, torque rating was the same for both engines: 460 lbs.-ft.

“L36” 427-cid V8
This car came with the “L36” 427-cid V8, equipped with hydraulic valve lifters, 10.25:1 pistons and features a Quadrajet 4-bbl carburetor, which has small primary barrels and extra large secondary barrels. This configuration developed 390-horsepower @ 5200 rpm with 460 lbs/ft of torque at 3600rpm.      
“L36” 427-cid V8
The Air Injection Reactor smog system was required for this application being a California car, and the heart of the system is this V-belt driven air pump. AIR was designed to deliver air to the exhaust ports in sufficient quantity to support oxidation of hydrocarbon and carbon monoxide emissions.
All the original AIR smog equipment was still intact on the car when purchased, and simply cleaned up and resprayed during the under hood detailing. Many 427-cid engines from this era were later modified with aftermarket exhaust headers, with these stock exhaust manifolds and emissions components tossed in the trash, however this car was never altered.    
transistor ignition system
$73.75 was the cost for the “K66” Delcotronic full-transistor ignition system upgrade. Others included a magnetic-pulse distributor, special coil, resistor and pulse amplifier. The system provided a better spark at high rpms and eliminated periodic maintenance, no points and condenser. The amplifier was mounted between the grille and radiator for cooling purposes. 
“MM” code Aztec Bronze.
Wide, ribbed body sill moldings and twin pinstripes are Caprice only items for 1966. Paint is “MM” code Aztec Bronze.   
Vinyl top
The all-new “limousine look” roof shape on the 1966 Caprice coupe was adorned with fleur-de-lis emblems and added an elegant appearance. Vinyl tops were optional at $79.00 and the roof cover fabrics came in two colors: black and beige.
“simulated magnesium wheel”
The factory referred to these wheel covers as being of “simulated magnesium wheel” design and came in 13-inch diameter (Corvair) and 14-inch sizes. These upgraded covers were factory-equipped N96 option code on this car.
Caprice
The twin simulated exhaust ports below rear window and chrome accents on the wrap around taillights are tell-tail signs from the rear view to distinguish between a Caprice and the lower status full sized Chevrolets. 
The addition of bright horizontal ribs were exclusive to Caprice models, car came with rear bumper guards for $9.50.
Luggage compartment has 28.7 total cubic feet of volume, the tubing on upper RH side is vent tube for fuel tank.  
Chevrolet frames
A torque-box design perimeter frame was used, with full-length side rails laterally joined by four welded-in cross members plus a bolt-in transmission support. Material thickness on 1966 full-size Chevrolet frames with 33-percentthicker gauge on the rails, said to be improved to fight corrosion.
While the armrests and door carpeting has been replaced, these are the original door panels as delivered from the factory back in 1966. Everywhere you look this car is immaculately detailed! 
Strato-bucket seat

When a Caprice Custom Coupe was ordered with Strato-bucket seat option for $200.15, it came with center console, special instrumentation, and lower instrument panel padding. Interiors of Caprice coupe and sedan models were inlaid with the rich look, simulated, of hand-rubbed walnut on doors, instrument panel, glove compartment and horn ring, with other higher-quality appointments, including color-keyed tufted pattern cloth and padded vinyl upholstery and thick, deep-twist carpeting.       

gauges

“The location of the instruments included with the buckets and console isn’t likely to bring raves from purists,” said Motor Trend Magazine’s tester. “Located vertically between dash and console, they’re not in the driver’s line of sight. But they have the saving graces of being complete, legible and well lighted, as well as being most tastefully laid out.” In reality, where else could have all these gauges been located? The instrument panel was already pretty well filled up, the factory had to put them somewhere!  

AM/FM pushbutton stereo radio
All-transistorized deluxe AM/FM pushbutton stereo radio, U69 for $133.80 is an eleven-transistor unit with nine diodes and provisions for optional Stereo Multiplex equipment. This radio uses a 31-inch antenna for optimum performance. 
Stereo Multiplex system
“For your listening pleasure” was the tagline on the U79 for $133.80, optional Stereo Multiplex system and included was separate volume, tone, F/R fader controls, twelve transistors and six diodes combined with multiple speakers, with balance on both stereo and monaural. An indicator light circuit signifies when the FM station is broadcasting a multiplex signal.  
 tilt and telescopic steering wheel

Available at extra cost of $79.00 the tilt and telescopic steering wheel provided greater driver comfort, easier entry and exit. Each adjustment can be made independently and performed while driving. Tilting is accomplished with a lever located below the turn signal control. There are two “up” positions and three “down” positions, in 6-degree increments from the normal driving setting. The locking ring below the horn button permits telescoping, with any desired in-out position possible within an approximate 3-inch range. Combined, the tilt and telescoping feature allows the wheel to be moved some 5-inches horizontally and 6.5-inches vertically.  

 tilt and telescopic steering wheel
With the beautiful condition of the interior, sitting behind the steering wheel in this classic Caprice reminds one of a brand new automobile. Great efforts have been put into every detail of the car, including a re-chromed dash bezel.  
1966 427 Caprice Custom Coupe

When the original owner left his prized brand-new to his nephew, who apparently wasn’t too keen on keeping the car for himself but rather drove to the Swap Meet where he offered it up for sale. The car had 81K on the odometer and was in great “survivor” condition, and as a one owner car it could be a fantastic restoration project.
