Vintage Car Life Road Test: 1968 AMC Javelin SST – Praising A “Dramatic And Successful Design Turnabout”

The editors of Car Life hadn’t been very impressed with AMC’s previous stab at the sporty car market, the fastback Marlin, but the exciting new AMC Javelin promised to be a better effort. In the magazine’s December 1967 issue, Car Life tested the Javelin in SST form with the 343 engine and four-speed. Here’s what they had to say about it.

When the Javelin debuted in September 1967, American Motors Corporation was a company in desperate need of a bright spot. The niche in which the Rambler had previously done so well was now heavily populated with domestic compacts and intermediates, and AMC sales were in freefall. The company lost over $12 million in 1966 and $75.8 million in a painful financial restructuring for fiscal 1967.

AMC changed its ad agency in June 1967 — this Javelin ad was a product of new agency Wells, Rich, Greene, founded a year earlier by the dynamic ad exec Mary Wells.

 

Strictly from the standpoint of numbers, the Javelin was not AMC’s most important product, and the initial sales target was a mere 35,000 units, roughly one month’s worth of Mustang production. However, the Javelin was vital in another way, because it was AMC’s best chance of rehabilitating the company’s frumpy, schoolmarmish image. This wasn’t a minor concern: In 1966, the Ford Mustang — and just the Mustang, not any other sporty car — outsold the entire AMC line by margin of 2 to 1. The Javelin had been in the works since mid-1965, and its styling had been previewed in the “Project IV” cars AMC had shown throughout 1966. Now, the question was whether the production version would get the right kind of reaction from the public and the press.

Initial reactions were positive: The Car Life editors found that when they pulled up in the SST, “small boys stopped their bicycles and stared, and grown-up boys stopped their cars and asked questions.” Unlike the hapless Marlin, the Javelin had the right proportions and “a pleasing coherence” of body design. The editors even liked the optional “Turbo-cast” wheel covers, although they found them hard to remove for tire changes.

Car Life‘s test car had the 343 cu. in. (5,624 cc) Typhoon V-8, with a four-barrel Carter AFB carburetor and a gross output of 280 hp and 365 lb-ft of torque. This engine had been introduced for 1967, but the text is wrong about it having “larger intake and exhaust valves” for 1968. (I think whoever wrote the text confused the specifications of the 343 with the 290 cu. in. (4,751 cc) version, which had smaller valves than the 343; the ’68 343 had 2.025-inch intake and 1.625-inch exhaust valves, the same size as in 1967.) Nonetheless, the 343 was a flexible engine, enough so that the editors thought it would have performed as well or better with a taller (lower numerical) axle ratio than the test car’s 3.54 axle.

The text’s complaints that the four-speed’s ratios were “too close together” may be confusing unless you look at the ratios in the spec table. Low gear in the four-speed transmission was 2.64:1, which would make this a wide-ratio gearset by ’60s standards. The problem was the intermediate ratios: 2.10:1 in second and 1.60:1 in third, which put second much too close to first and left a big gap between second and third.

With the narrow spacing between first and second, second gear wasn’t very useful: Shifting at 5,300 rpm, you were in second gear at 43 mph and had to make another shift into third at 54 mph. Car Life found that the Javelin was almost as quick through the quarter mile starting in second rather than first! They liked the fully synchronized four-speed gearbox itself, but these ratios just didn’t suit the 343 engine.

My guess is that taller second and third gears — say, around 1.80 in second and 1.40 in third — would have helped the Javelin’s acceleration noticeably, probably cutting about a half-second off the 0 to 60 mph times. AMC apparently decided the same thing: For 1969, the four-speed used behind Javelin and AMX V-8s got a close-ratio gearset with a 2.23:1 low, 1.77:1 second, and 1.35:1 third.

The editors also thought performance would have benefited from “larger, fatter tires.” However, with its E70-14 tires (roughly equivalent to a modern 205/70R14), the Javelin SST actually had a decent amount of rubber for this time; Car Life‘s 1967 Pontiac Firebird 400, which had Firestone Wide Ovals in this size, didn’t have nearly the traction problems of the Javelin. A slightly wider F70-14 size on wider wheels would probably have helped, but I wonder if the Javelin might have done better with a different brand of tire than the Goodyear Speedway Wide Tread, even in the stock size.

Car Life had been underwhelmed with the disc/drum brakes on their ’67 Marlin, which had suffered early rear-wheel lockup and faded its front discs readily. The Javelin had two big advantages over the Marlin: a proportioning valve to delay pressure to the rear brakes, and over 400 lb less weight to stop. However, while the text of this road test praises the “smooth, progressive and consistent” stopping and minimal fade, the data panel isn’t quite so favorable: The panel notes “moderate” control loss in a panic stop, and the rate of deceleration (24 feet per second per second) was actually only about 10 percent better than the Marlin. Also, you couldn’t get disc brakes on a six-cylinder Javelin.

The test car didn’t have power steering, but it had the “quick ratio” manual option. With 4.2 turns lock to lock, this was slow as well as heavy, although the power steering was only a bit quicker (3.8 turns). The standard non-power ratio was lighter, but slower still: 5.1 turns lock to lock.

The Javelin SST was not a performance option, but a trim series, costing $105 more than a basic Javelin and providing amenities such as reclining bucket seats, woodgrain trim, and a simulated wood sports steering wheel. Car Life‘s test car, which was an early-build example, also had the $266 GO package, which included the 280 hp 343, dual exhausts, front discs, and the disappointing E70-14 tires. The GO pack also included the handling package, which had firmer springs and shocks and a larger front anti-roll bar, along with wider 5.5-14 wheels; this H-D suspension package could be ordered separately for $17.

(As a side note, I think the Car Life crew might have misread the AMA specifications, as the spring rates listed in the data panel look to be from the H-D package for six-cylinder Javelins, which had softer springs and a smaller anti-roll bar than the V-8 H-D suspension. I couldn’t find 1968 AMA specs, but the 1969 specs list the V-8 Javelin heavy-duty suspension as having spring rates of 115 lb/inch front and 136 lb/inch rear, with an 0.94-inch anti-roll bar.)

Surprisingly, there’s almost no discussion of the Javelin’s handling, except that the Car Life editors felt the handling package wasn’t worth having. They said:

We ordinarily find that performance and handling benefits from the installation of heavier, stiffer springs and shocks, but in view of the Javelin’s problematical road adhesion under full power we believe the buyer would do well to pass up this option and stay with the softer stock components. This will add a bit to the car’s corner lean and dipping over heavy bumps, but should help keep the rubber on the road.

I find this recommendation very questionable: If the Goodyear E70-14 tires were the weak link, softer springs wasn’t going to make them bite any better, so all the standard suspension was likely to accomplish was discouraging drivers from discovering the tires’ limited grip. Since the standard suspension also came with narrower 5.0-14 wheels (and standard 6.95-14 tires, which were over an inch narrower than the E70-14 rubber), it might have had even less grip.

Considering the traction problems and less-than-ideal gearing, the Javelin’s straight-line performance was still quite good:

  • 0 to 30 mph: 3.5 seconds
  • 0 to 60 mph: 8.1 seconds
  • 0 to 100 mph: 17.7 seconds
  • Standing quarter mile: 15.4 seconds at 93.0 mph

The quarter mile elapsed time wasn’t in the first rank for 1967, but better tires and different gearing would have put the Javelin in a more competitive position without much tinkering, and AMC would soon add a bigger 390 cu. in. (6,384 cc) engine option, with 315 gross horsepower.

Around this time, AMC was actually beginning a concerted effort to establish the Javelin in competition, something that would have been unthinkable for America Motors even a year or two earlier. Just weeks before this issue of Car Life appeared on newsstands, Jim Jeffords and Ron Kaplan had founded Javelin Racing Team, which would prepare the Javelin for the SCCA Trans Am series, and later AMC ads would actually invite potential customers to “Test Drag a Javelin.” By the summer of 1968, the buff books would be reporting on the new array of over-the-counter performance parts available for AMC V-8 engines — things were changing in Kenosha.

Exhaust emissions control had been required on most new California cars since 1966, and starting with the 1968 model year, federal regulations limited the exhaust emissions of engines over 140 cubic inches to no more than 275 parts per million hydrocarbons and 1.5 percent carbon monoxide by volume. With the six-cylinder Javelin and V-8/automatic cars, AMC was able to get by with the cheaper “Engine-Mod” package, which was basically the same as the Chrysler “Cleaner Air Package”, involving modifications to the mixture settings and distributor, plus a thicker head gasket that slightly reduced the compression ratio. This wasn’t enough for manual-shift V-8 cars, so they used the “Air-Guard” air injection system (basically similar to the GM Air Injection Reactor system), with a Saginaw air pump that injected fresh air through special ports in the exhaust manifold. Running the 19 cu. in. (316 cc) air pump cost some power (which wasn’t reflected in the gross power rating), and as the text notes, air injection made the engine prone to backfiring.

The text contains no mention of rear seat comfort, not really a priority for this class of car, but the Car Life editors liked the front seats and thought the controls and instrument layout were generally good. Unfortunately, the “Rally-Pak,” which included a tachometer, oil pressure gauge, ammeter, and clock, had to be dealer-installed, and the editors noted that “part of the tachometer is often hidden by the steering wheel.”

Car Life‘s biggest complaint about the interior, other than some minor early-production assembly flaws, was the door handles, which used a pull-down lever ahead of each door armrest to ensure that the door would automatically lock when pulled closed. This was handy if you understood how it works, but if you didn’t, it made it “possible to be embarrassingly outside wanting to get in—or inside not knowing how to get out quickly.”

Overall, Car Life was impressed by the Javelin, concluding:

With its extremely attractive body design, a range of engines and transmissions from economical to dynamic, optional appearance and performance packages of every kind, plus American Motors’ hard-won reputation for solid durability, the Javelin has a lot of things going for it … Further, this dramatic and successful design turnabout shows a welcome strength and purpose … May AMC’s reward be in direct proportion to its decisiveness and courage.

Unfortunately for AMC fans, such reward was not really forthcoming. Here’s how to production figures for the first-generation Javelin and related AMX shaped up:

Javelin/AMX Production, 1968–1970
Model Year Javelin AMX Total
1968 55,124 6,725 61,849
1969 40,675 8,293 48,968
1970 28,210 4,116 32,326
Total 124,009 19,134 143,143

There was nothing terribly wrong with the first-generation Javelin — the performance of the test car was quite competitive with the Camaro SS350 Car Life had tested earlier in the year — but it wasn’t a standout either, a solid “B” effort in a crowded field, from a brand whose uncoolness was rapidly becoming terminal.

AMC was trying desperately to change that, which was the whole point of the Javelin; almost every sale was a conquest sale. However, based on its underwhelming volume and limited market share, the Javelin seems like too little and too late, despite its good first impressions.
