Vehicle Description
1973 Chevrolet Chevelle SS - True Big Block Super Sport with Rare
Swivel Bucket Seats This is a very rare and documented 1973
Chevrolet Chevelle SS. The VIN confirms it as a true Super Sport
equipped with a factory 454 big block engine. While the engine
appears original and the previous owner states it is, there is no
visible VIN stamp, indicating the block was likely decked during a
rebuild. While 1973 Chevelles typically do not have factory build
sheets, this car includes an original identification card that was
found inside, further supporting its authenticity and originality.
The car features desirable and rare swivel bucket seats, adding to
its uniqueness and collectability. The paint was redone in its
original color in 2016 and remains presentable, though it does show
minor signs of age including some scratches and bubbles. Under the
hood, the original 454 block has been professionally bored .040
over and upgraded with high-performance internals. The build
includes Keith Black 26cc dome hypereutectic pistons, a forged
crankshaft, mildly worked 049 heads with 2.19 and 1.88 valves, and
a 10.2:1 compression ratio. The valvetrain is fitted with full
roller rockers and a Comp Cams Magnum 292H cam. Additional
performance parts include Hooker Super Competition headers, a
Holley Strip Dominator intake manifold, and a Holley 850 double
pumper carburetor. The engine was built by Topline Energy in 2019
and has been carefully maintained since. It currently runs on
Valvoline VR-1 Racing Oil 10W-30. The power is delivered through a
Turbo 400 transmission with a 10-inch converter and 3200 stall,
installed in 2019. Out back, a 12-bolt rear end houses a Moroso
Brute Strength posi unit with 3.73 Richmond gears and new bearings.
The car rides on Nitto drag radials installed in 2019. Additional
mechanical upgrades include a new gas tank and sending unit (2019),
front-end bushings and a new steering box (2019), complete new
weatherstripping (2019), a full new exhaust system (2021), and new
rally wheels (2021).
