1973 Dodge Challenger 340 Rallye Package �€" Broadcast Sheet
Documented, Dark Silver Poly with Black Vinyl Top Why This Car Is
Special The 1973 Dodge Challenger is the end of a short,
significant story. Dodge introduced the Challenger for the 1970
model year as a direct answer to the Ford Mustang and Pontiac
Firebird, built on the Chrysler E-body platform. It was a wide, low
pony car with one of the largest engine option lists in its class.
By 1973, however, emissions regulations, rising insurance costs,
and a market shift toward economy cars had drastically narrowed
what Chrysler was willing to offer. The 340 small block was pulled
from production after 1973, making this the absolute last year a
buyer could walk into a Dodge dealership and order a Challenger
with that engine from the factory. That distinction matters to
collectors, and it is one of the reasons well-optioned 1973
Challengers with documented build histories are increasingly hard
to find. This particular 1973 Dodge Challenger carries the factory
A57 Rallye Package, confirmed by the broadcast sheet RPO codes. The
Rallye Package was Dodge's performance-appearance group for the
Challenger in its later years, bundling together functional and
visual upgrades that separated it from the base hardtop. What makes
this car especially traceable is that the broadcast sheet survives,
giving researchers and buyers a direct record of how this car was
ordered and built at the factory. Build date encoded in the vehicle
records places assembly at October 10, 1972, meaning this is an
early 1973 model year car. The VIN structure confirms it was built
at the Hamtramck, Michigan assembly plant and identifies the 340
four-barrel V8 as the installed engine �€" the 'H' in the fifth
position of the VIN is the Chrysler engine code for the 340
two-barrel or four-barrel small block, consistent with the RPO E55
four-barrel specification listed on the broadcast sheet. The color
combination is Dark Silver Poly (paint code JAS) over a full black
vinyl top, with a black interior. Silver over black is one of the
more purposeful combinations available on the 1973 Dodge Challenger
�€" understated at a distance, precise up close. The car has been
restored rather than left in raw survivor condition, which means
the mechanicals, interior, and exterior all present at a level
appropriate for driving and showing without the anxiety of a
fragile unrestored car. Features List - 340 CID 4-Barrel V8, 275hp

undercarriage Mechanical The 340 cubic inch small block is the
correct engine for this car and one of the better reasons to seek
out a 1973 Dodge Challenger specifically. Chrysler's 340 had a
strong reputation throughout its production run from 1968 to 1973.
It used a high-winding, free-breathing design with a short stroke
relative to its bore, which gave it a character distinct from the
longer-stroke LA engines. In RPO E55 four-barrel configuration for
1973, it was rated at 275 horsepower �€" a number that reflected
the industry's shift to net horsepower ratings that year rather
than gross, so direct co
