1970 Chevrolet Chevelle SS 454 �€" Cranberry Red, LS5 Big Block,
TH400, 12-Bolt Rear Why This Car Is Special The 1970 Chevrolet
Chevelle SS 454 sits at the top of the muscle car hierarchy, and it
has for more than fifty years. This is not an opinion �€" it is a
market fact backed by auction results, collector demand, and the
simple reality that no other GM A-body of the era was offered with
as much displacement from the factory. The 454 cubic inch big block
was new for 1970, and Chevrolet offered it in two states of tune:
the LS6 at 450 horsepower and the LS5 at 360 horsepower. The LS5
was the more streetable of the two, making it the version most
buyers actually ordered. It was hydraulic-cammed,
emissions-friendly enough for daily use, and still capable of
running the quarter mile in the mid-13-second range in period
testing. The VIN on this car confirms it left the factory as a
genuine Chevelle SS, built at the Kansas City assembly plant in
1970. The body style is the two-door hardtop Sport Coupe, the most
desirable configuration in the SS lineup. This particular car
presents in Cranberry Red over a black vinyl interior �€" a
combination that photographs well but, more importantly, looks
exactly right in person. One important detail worth noting up
front: the engine currently under the cowl induction hood is a GM
LS5 454 unit dated to 1973, not a date-coded 1970 block. This is
disclosed clearly because informed buyers at this level expect it.
The engine is correct in specification to what originally came in
the car �€" same LS5 designation, same Quadrajet carburetion, same
Turbo-Jet 454 air cleaner �€" and it has been installed with
attention to period-correct appearance. Buyers focused strictly on
numbers-matching originality will note this distinction. Buyers
focused on driving a properly sorted, big-block Chevelle SS will
find that this car delivers exactly that. Features List - GM LS5

454 was Chevrolet's entry point into the big block SS lineup in
1970. It used a hydraulic lifter camshaft, a single Rochester
Quadrajet 4-barrel carburetor, and rectangular-port cylinder heads.
Factory-rated output was 360 horsepower and 500 lb-ft of torque,
though many historians and enthusiasts believe those figures were
conservatively published in part due to the insurance climate of
the era. The engine in this car is a GM LS5 454 unit from 1973,
installed with the correct Turbo-Jet 454 air cleaner and
period-appropriate detailing. The engine bay presents well, with
the block painted in the correct Chevrolet orange, chrome valve
covers, and clean wiring throughout. Backing the 454 is the
Turbo-Hydramatic TH400, one of the strongest automatic
transmissions General Motors ever produced. The TH400 was used
across GM's performance lineup for decades, from muscle cars to
trucks, and it is well supported in the rebuild and performance
aftermarket today. Cooling is handled by an aluminum radiator, an
upgrade over the original that improves thermal capacity without
affecting the under-hood appearance in a meaningful way. Out back
sits the GM 12-bolt rear axle, the correct and most desirable un
