1966 Chevrolet Chevelle SS 396 Convertible �€" Show-Quality Total
Restoration Why This Car Is Special The 1966 Chevrolet Chevelle SS
396 is widely regarded as one of the most complete muscle car
packages Chevrolet ever put together. In its second year of
production, the SS 396 had already found its stride �€" offering
buyers a purpose-built performance package with real factory
credentials rather than a parts-bin special. This particular 1966
Chevelle SS 396 is a convertible, which adds a layer of
desirability that hardtop coupes simply cannot match. Convertibles
represented a small fraction of total Chevelle SS production in
1966, and those built with the L34 396 are rarer still. What makes
this car particularly significant is the engine under the hood. The
L34 was the middle-ground big block in the 1966 SS 396 lineup �€"
rated at 360 horsepower from the factory and sitting between the
base 325-hp L35 and the top-of-the-line 375-hp L78. The L34 used a
hydraulic-lifter camshaft and a Holley four-barrel carburetor on an
aluminum intake manifold. It was a strong, streetable combination
that gave buyers most of the L78's performance with more daily
drivability. This is not a small-block car that someone stuffed a
396 into �€" the VIN confirms it was built from the factory as an
SS 396, assembled at the Kansas City plant in 1966. That matters to
serious collectors. The restoration on this car was no weekend
project. The total investment pushed into six-figure territory, and
it shows in every panel, every seam, and every component
underneath. This is a show winner, and the quality of the work
backs that up. Features List - 396 cubic inch L34 Big Block V8, 360

award winner Mechanical The L34 396 was one of the more capable
engines available in a production American car in 1966. Displacing
396 cubic inches, the engine produced 360 horsepower and 410 lb-ft
of torque through a hydraulic flat-tappet camshaft, 10.25:1
compression, and a 625-cfm Holley four-barrel. The chrome
'Turbo-Jet 396' air cleaner badge is period-correct and visible in
the engine bay photos. The engine bay has been restored to show
standards with correct orange block paint, chrome dress pieces, and
a detailed underside. Backing the L34 is a Turbo-Hydramatic TH400
automatic transmission, which was the strongest automatic gearbox
GM offered in this era. The TH400 was used across GM's performance
and heavy-duty lineup through the late 1960s and well into the
1970s. It is a robust, well-understood unit that holds up well
behind big-block power. You can see the TH400 pan clearly in the
undercarriage photos �€" it is clean and freshly detailed. Out
back, the car runs a GM 12-bolt rear axle, the strongest
passenger-car rear end GM produced in the 1960s. The 12-bolt has a
wider ring gear than the 10-bolt and a stronger pinion support,
which is why it remained the preferred axle for big-block SS cars.
The axle housing and pumpkin have been refinished and are clearly
visible in the undercarriage shots. Power front disc brakes were a
factory option on the 1966 Chevelle SS and represent a meaningful
upgrade over the standard drum setup. Combined with power steering,
this car drives more like a modern vehicle than most period muscle
cars. The undercarriage photos show clean, freshly coated framing
with no rust, no patch panels, and no shortcuts. An Alloyworks
aluminum radiator has been fitted for improved cooling capacity �€"
a smart upgrade on a big-block convertible that may see extended
driving in warm Florida weather. Interior The 1966 Chevelle SS 396
