When a 440 grabs one's ear and says hello, it simply
can't be ignored. Up at the other end of those two pipes protruding from
under the rear bumper are some serious cubic inches and pistons like
buckets squeezing chunks of air and distilled petroleum product into
little wedge-shaped bits and spitting them out to tumble down and around
and out the back and go wuggawuggawugga. And that's just at idle.
Subtle it ain't. It goes with the territory, one
might suppose. The 440 Super-Commando V-8 in question is bolted to
the unit body of a 1970 Plymouth GTX painted a violent LimeLight green
that glows like Chernobyl at midnight. A visual impact equal to
trumpets simultaneously playing E-flat and D, it can't be missed.
The Plymouth Division made 7,748 GTX's in 1970, and probably not very
many of them were wrapped in this, um, striking hue.
It's
an unrestored original owned for the past twelve years by Jerry and
Donna Clymer of Scotrun, Pennsylvania. Unmodified it is but for
larger fuel lines (better to feed you with, my dear) installed by a
previous owner for the optional carburetors. Ah, carburetors.
Remember them? Quaint devices for sucking droplets of gasoline
into a moving airstream? The 440 cubic inch V-8 has three, with
two throats per, a $119 package that thumped output to 390 bhp, up from
375 bhp for the "base" 4bbl single-carb 440. With different
jetting, each carb front to rear had its own part number. The
front and rear were also vacuum operated, the front and rear flopping
throttles open when intake manifold vacuum dropped under hard
acceleration. Not just a new manifold and carbs, the 440 Six
Barrel engine also included a new crankshaft, camshaft, tappets, timing
chain, connecting rods, pistons and rings, valves and rocker arms.
Even under wide-open no-load dyno testing, the valves would bend before
the engine would blow.
The 440/six was a more affordable engine option for the
GTX than the "Street Hemi," which made 426 peak horsepower on the
dynamometer but, in the GTX, cost $711, almost six months rent in 1970
dollars. With two four barrel carbs, a more radical cam and
hemispherical combustion chambers, the Hemi was also less drivable than
the 440 and lacked the bigger engine's bottom end punch.
The GTX was the top of the Plymouth "intermediate"
lineup, which had Belvedere on the bottom, with Satellite and Sport
Satellite above that. The fabled Road Runner was a bare-bones
go-fast-for-cheap Belvedere, while the GTX was a "gentleman's hot rod"
Satellite. Aimed at the more mature and wealthier over-25 age
group, the GTX sported deluxe trim and was available only as a 2-door
hardtop. Yes, kids, that means there was no B-pillar and yes, the
rear windows rolled up. Chrysler's 3-speed Torqueflite was
standard, the 4-speed manual optional. Plymouth's trick hood
scoop, offered on Road Runner and GTX, was the Air Grabber hood scoop.
Flip a switch under the dash and a trap door in the hood rose to admit
cool air directly to the air cleaner. It was good, said Plymouth,
for about .1 second in the quarter mile. It was better for
intimidating the guy in the next lane at the stoplight grand prix. The
door had the "GTX" logo positioned "upside-down" so that when open the
logo was right side up from the passenger compartment.
To slide behind the wheel is to remember another era of
automobile. The steering wheel is big, close, skinny and hard.
The lap belt seems woefully inadequate. The bucket seats lack
lateral support but are comfortable enough as chairs, though the Hurst
pistol grip shifter, way up here and close to the wheel, suggests more
than just lounging. The instrument panel has deep set gauges, with
full instrumentation including a tach-clock combo that serves neither
purpose well. Fit was woeful, but we didn't know any better.
The body design, if not Modern Aerodynamic, was classically American as
Levi's, a T-shirt and Ray-Ban shades.
The engine and drivetrain more than made up for any and
all shortcomings, however. From the driver's seat, exhaust rumble
is subdued and matched by whine from the heavy-duty gearsets. The
GTX motors about docilely, though the broad hood looks a soccer field
tacked ahead of the windshield. It makes a narrow winding road a real
challenge, the big steering wheel allowing only general suggestions for
the car's direction. Despite a sloppy on-center feel, it loves
going straight, however.
That's good, because the right pedal's a firecracker,
and with the close-ratio gearbox, it's
cacophony-shift-cacophony-shift-cacophony and there's no need for fourth
gear because the speed limit's already ancient history and yeah, if it
were 1970 and one heard wuggawuggawugga in the next lane, one had best
take it seriously. And buddy, trust me. wuggawuggawugga from
a GTX in the next lane should still give one pause...
