Vehicle Description
This is believed to be the only 315 HP high performance 4 speed Jet
Star 88 built in 1964. It was ordered from the factory nearing the
end of the 1964 production year for the sole purpose of placing a
special order for the new 1965 Jet Star 88 only UG code high
performance 315 HP engine that was not available in 1964. The
highest hp in 1964 was the TG code 290 hp engine. This increase of
25 hp was the goal of this special order. CHEVY CALLED THESE COPO
ORDERS. This is a 1 of a kind car and this is the only known and
documented example. This beauty has just 35,254 actual miles. It
has been confirmed by the General Motors Heritage Center as having
come from the factory with the new 1965 only 315 hp UG code high
performance engine before it was available to the general public
for the 1965 model year. Olds only offered 4 speeds in the full
sized cars for 3 years 1964-65-66. Extensive research including the
original 1964 and 65 Olds factory options lists and dealer
brochures. The original Olds factory engine identification charts
obtained from the General Motors Historical Archives and many more
references shows there were no 1964 UG code 315 HP cars made. This
is an extremely rare highly documented car.
