Vehicle Description
11,679 original miles. Matching-numbers. 3 build sheets. Known
ownership history. Please review all the information and more than
130 photos on our website at www.HarwoodMotors.com, which includes
documentation, numbers analysis, and photos of all the relevant
components. The summary is that this 1970 Chevrolet Chevelle SS 454
LS6 hardtop is likely the most authentic unrestored LS6 available
anywhere. It has 11,679 original miles, is 100% numbers-matching,
and is fully documented with THREE build sheets, original
Protect-O-Plate, and a known ownership history from Day One. It has
been freshened but never restored, and wears its original paint,
interior, and trim, and carries its original LS6 engine that has
been freshly rebuilt. It will be very difficult to find a better
LS6 than this. Here are all the relevant details on every single

of the car needed nothing but cleaning. The original
factory-applied code 48 Forest Green paint is almost as new, and,
in fact, we have a letter from owner Randy Becker to the president
of the Chevelle club complaining that he was tired of all the
'experts' telling him that the car HAD to be a repaint because it
was so nice. All the readings on a paint thickness gauge are
between 3 and 5 mils, with nothing over 8 mils, which suggests
factory paint. All evidence points to this being original paint on
this incredible Chevelle. The black vinyl top is also completely
original and in spectacular condition. The chrome and stainless
trim has never been removed and shows almost no wear or signs of
age. The original black bench seat interior was removed and
cleaned, and while it was disassembled they found not one, not two,
but THREE completely intact, legible build sheets. The optional U14
Rally Gauges are all operational and it carries its original 6500
RPM LS6 tach. Everything works except the clock, and the radio
powers up but does not pull in stations which is likely due to a
broken wire from the windshield-mounted antenna (the windshield is
original, and you'd be crazy to replace it to make the radio work).
In the trunk you'll find factory-applied spatter paint, original
trunk mat, and the original spare tire that looks like it has never
been used. The original, matching-numbers 454 cubic inch LS6 V8 was
fully rebuilt last year with machine work and dyno tuning by Badman
Racing Engines. Dyno sheets show a rather stout 463 horsepower and
512 pound of torque, right in line with what a proper LS6 should be
making. This is unquestionably the car's original engine, with a
correct date stamp, suffix code, and partial matching VIN on the
stamping pad. It is most certainly NOT a restamp or a forgery and
the car has been vetted by guys like Chris White and Rick Nelson,
so it has its credentials in order. It starts and runs superbly,
and is surprisingly docile for such a monster of a 1970 powerplant.
Even the mechanical valvetrain is quiet and well-behaved. It's
savagely fast, I'm sure (with only a few hundred test and tune
miles, it's not yet time to hammer on it), but it also just works
like a car should work. Easy starts, nice idle, smooth power, no
fussiness in traffic. Impressive. At the same time, the original,
numbers-matching TH400 3-speed automatic transmission was rebuilt
and Walt's racing torque converter was replaced with a proper unit.
Out back, the 4.56 gears were replaced by original-spec 3.31s on a
Posi, and yes, that's the original rear end housing with correct
date codes. It also carries a Gardner exhaust system with correct
stamping codes, which cost several thousand bucks all by itself.
14-inch SS wheels carry F70-14 Goodyears. Documentation includes
three build sheets, Protect-O-Plate, owner's manual, ownership
history, correspondence, receipts, dyno sheets, an appraisal from
1986 when the car showed 11,124 miles, and more. Please review the
photos and information , because this is an extraordinary find. Few
Chevelles are more correct than this one and thanks to the low
mileage, it remains in exceptional condition. For the enthusiast
who seeks the best, this car will measure up in every way that
matters. You will look for a long time before finding a better LS6
Chevelle than this. Call today! Harwood Motors recommends and
