Body ID - 1970
1970 was a banner
year for the Intermediate Oldsmobile's. Performance was at its peak
and styling was exciting. F85 was again one 2dr sport coupe for
70. Added to the line up were the Rallye 350, the Indy Pace Car
442, the restyled Cutlass Supreme on the "A Special" framework and
the SX package for the Supreme. 442 now boasted a 445-ci power plant
and horsepower was at an all time high. Many other "W Machine" goodies
were also offered for the model year. Convertibles were now only
offered on the Cutlass Supreme and 442 lines with the 442 version
being nothing more than a Supreme with all the hi performance goodies.
So many hot models
were produced for 70 that is's hard to know where to start. There
was the Rallye 350, the Cutlass Supreme SX, the W31, the 442 W30,
and the Indy Pace Car.
The intro level A
body was the F85 Sport Coupe. The base engine was the Chevy in-line
6 or the 250hp 350CI Rocket V8. There was no wheel well molding
or belt-line trim. The car may have one of two hoods: the one shown
below or the 442/Cutlass S style hood with 2 raised areas having
chrome louvers at the rear. A rocket logo is used between the grills
on the center section with F85 emblems used on the fenders, trunk
lid, and glove box door. Dash should be void of all wood grain trim
and there should be very little flash and design to the seat cover
stitching. All 70 F85's are "post" cars, meaning they
have window frames on both the doors and quarter windows, although
some of the car's posts are body color having no chrome (like shown
below). The grills should be the standard issue Cutlass S, F85 plastic
jobs with a small grid pattern.

The Cutlass S for 1970 carried 2 models. A Sport Coupe (post model) and a Holiday Hardtop.
Cutlass S Sport Coupe
The Cutlass S Sport
Coupe was very similar to the F85 in basic appearance. The S did
receive chrome wheel well moldings, some also had chrome belt line
trim. The S also had a flashier interior and all had the domed hood
described above. Emblems used on the S were a S logo on the hood
center section between the grills, Cutlass scripts on the fenders
with S logos just below them and a Cutlass script on the trunk lid.
These have the small grid pattern grills as well. Most all of these
cars should have chrome surrounding the window frames.
Cutlass S Holiday Hardtop
Same as described above but with out the window frames.
The 442 was based
directly on the Cutlass S platform with the exception of the convertible
which we will talk about shortly. As such it was also available
in the Sport Coupe and Holiday Hardtop. It shared the same interior
as the S as well as the same hood and basic body trim. The emblems
used on these were 3 separate numerals that spelled out 4-4-2. These
were used on the hood center section, both fenders, the trunk lid
and glove box door. There was an optional hood, code W25, that came
as part of a forced air induction package available on almost all
V8 F85 based cars. The hood featured large twin openings at the
front of the hood. (see photos below) Another item almost exclusive
to the 442 is the "notched" rear bumper. This has two
cutouts just below the taillights for the exhaust to exit straight
out. These cars should also have chrome "Trumpets" on
the tips of the exhaust pipes. The W30 received special striping
on the hood and sides, which was also optional on all F85's. The
grills for all 442's were more of a vertical design, having eight
oval shaped openings per side.
The convertible 442's are based directly on the Cutlass Supreme platform. These cars share the same interior and body style as the Supreme's but have all of the usual 442 trim.
The W30 Option,
only offered on the 442, added cold air induction, a special "Ram
Air" hood, a more radical camshaft, red inner fender wells,
special paint and W30 emblems, aluminum intake manifold, heavy duty
cooling, and disc brakes.

The Cutlass Supreme
for 1970 was restyled and given it's own body designation. It now
is considered an "A Special", a platform shared with the
Pontiac Grand Prix and the Chevrolet Monte Carlo. These are what
GM called "Personal Luxury Vehicles". All Oldsmobile convertibles
from 70-72 are based on this body. The 442 convertible is nothing
more than a Supreme outfitted with 442 running gear and markings.
The Supreme marked Oldsmobile's highest trim level for the A body
line-up. Besides the noticeable body differences, these cars used
special grills (although I have seen the standard Cutlass grill
more than once on a Supreme) that are more of a waterfall style
with many vertical lines. There was also a special lower body stainless
trim about 2" tall that encircled both front and rear side
markers and traveled the length of the car. Markings are as follows:
A standard rocket on the front of the hood (much like the F85 piece)
Cutlass scripts on both fenders, and trunk lid, and a Cutlass Supreme
script on the glove box door. Hardtop models will also have a "C/S"
script on each sail panel or C pillar. Most of these cars also have
a Rocket emblem that surrounds the trunk lock.
The interior for
the Supreme was noticeably nicer than It's "S" and 442
siblings. The base bench seat for the Supreme was a split bench
with center arm rest, which from behind is hard to tell if it has
bucket seats or not. It is not uncommon to find a Supreme with bucket
seats and no center console. I have seen several this way, and would
venture a guess that there are many more.
Y79 SX Option
The Y79 SX option,
only available on the Cutlass Supreme, offered some basic 442 items
for the Supreme. It included the 442 suspension with heavier springs,
boxed lower control arms in the rear, front and rear oversized sway
bars, dual exhaust with the notched rear bumper, and special emblems
for the front fenders.
The W32 option required
the Y79 package first and was nothing more than an engine option
for the Cutlass Supreme SX. The W32 engine, however, was no ordinary
option for 70. The W32 was the exact same engine used in base 442
models, so for all intents and purposes a Y79 SX with the W32 was
a 442 in disguise.
