The badge says Monza, but I’m thinking more Dakar

It’s got distinctive looks, great traction, and a horizontally opposed six-cylinder engine. No, it’s not a Subaru Forester—it’s a Chevy Corvair. Old-time Vermonters I keep encountering swear by the little air-cooled Chevrolets as cars that would, Beetle-like, go anywhere in the winter and get home again. The rest of the world sees Corvairs as “the poor man’s Porsche” and, you know, I like Porsches too—providing they’re the safari’d kind.

Safari cars are usually moderately lifted versions of regular street cars with knobby tires, extra lights, skid plates, and whatnot to permit them to go offroad or at least down sketchy, class D fire roads of the type that we have a lot of in the remoter reaches of the Green Mountain State. A safari car is kind of like a Group 11 or Baja Bug, just with any other kind of car than a Volkswagen Type 1.

Corvairs have their own off-road history, having made excursions both through the Darien Gap and into the swamps of Florida back when Chevrolet was pushing them as capable compacts more than sports cars. Since then, however, most builds lean in the direction of emulating the Fitch Sprint or Yenko Stinger SCCA contenders.

Still, there are a lot of Powerglide-equipped Corvairs that will never run with the four-speed cars on an autocross track but could be used for other vehicular adventures. This is a rare (unique?) case of me putting my time and money where my mouth is: I already own a near-identical car, and this is essentially the plan I have for it, though here we’ll take a look at how to safari a 1962 Chevrolet Corvair Monza listed for sale on Hemmings.com.

Suspension


This is how low a stock ’62 Monza is on undersized, 13-inch tires.

To start with, don’t imagine trying to replicate the New England Forest Rally in this thing. That’s a whole different car, incorporating a roll cage. For moderate driving, I envision just enough lift to deal with substantial ruts and clear oversized wheels and tires. That’s maybe an inch and a half to two inches over stock.

To accomplish that, the right way is new, taller springs and shock absorbers to match. Those aren’t something available off the shelf for Corvairs because most people want to lower their car or keep it stock height rather than go up. Spring spacers are another option, but kind of weak sauce for something intended as permanent.

It goes without saying that fresh bushings and an in-spec, adjusted steering box are mandatory before any modifications begin. You don’t want to compound deferred maintenance with weird changes.

The biggest weak points in a Corvair for long-term ownership are the rear wheel bearings. The wheel bearing for the swing-axle car was a unique design that interchanges with nothing except the ’61-’63 Pontiac Tempest. Further complicating things, the ’60-’62 design will fit a ’63-’64 car, but the slightly redesigned 1963-type bearing won’t fit a 1960-’62 Corvair. They’re not reproduced and weren’t intended as a serviceable part. The best thing to do, it seems, is to carefully drill a hole in the housing, install a plug (or a Zerk fitting—but some reports indicate that may not allow sufficient flow) and re-lubricate the bearing periodically. Having a useable spare set on the shelf also seems to be a wise mov

​Brakes, Wheels and Tires

Speed is the enemy of brakes. This isn’t a high-speed build. Ergo, it doesn’t need bigger brakes. That’s good because the early model Corvair doesn’t really lend itself to brake upgrades. In the front, it’s simple enough to swap to five-lug disc brakes, but you’re pretty much stuck with four lugs in the rear unless you can dig up and shorten a pair of axles from a Corvair 95 (that’s the van/truck version, which used front suspension more like that of an Impala than the standard Corvair unit).

One upgrade that I do demand and have already installed is a dual-reservoir master cylinder. Losing one of four brake lines shouldn’t mean losing all four brakes!

I’ve never been a fan of 13-inch wheels—probably because I’ve seen too many of them wearing undersized tires. There are better options today for Corvair radial substitutes than there used to be, but 14- and 15-inch wheels are way better supported. My feeling is that a 25.5-inch diameter looks best on a car this size, so I’m running 195/75R14 Firestone Winterforce snow tires.

It happens that I had easy access to 14-inch Ford Maverick wheels, which have the same four-lug bolt pattern as a Corvair, but a slightly smaller center hole. I had our friendly local machine shop open them up for me and used ’59 Chevy dog-dish hubcaps, but a more straightforward approach would be to grab a set of 14-inch aftermarket four-lug wheels (and matching ‘56 Chevrolet-style hubcaps) from someone like Wheel Vintiques.

One caveat here is that at extremes of suspension deflection while the wheels are turned, they sometimes catch the fender lip—hence the recommendation to raise the suspension slightly. Otherwise, 185/75R14 tires might be the ticket to avoid interference.

​Engine

Although the ad says otherwise, according to the crossed-flags badge on the decklid, this car has the 102-hp Super Turbo Air engine. Like all ’61-’63 Corvair engines, this is a 145-cu.in. boxer six. For 1964, Chevrolet stroked the 145 out to 164 cu.in., raising the formerly 102-hp engine’s output to 110 horsepower. The 102 is a good engine, but the 110 is an absolute stalwart.

I’ve already sought out a 110. Mine’s a ’65-vintage unit. A ’64 engine would be even better because it would come a lot closer to being a drop-in swap to the ’62 engine bay. Installing the later engine requires some parts shuffling—and a few ’64-only pieces—but is doable.

Alternately, I suppose you could have the 102 rebuilt with the 110 crankshaft inside; making a 110 completely disguised as a 102 save for the telltale harmonic balancer.

How I staved off the “inevitable” alternator swap for my Corvair by fixing my broken generator – David Conwill @Hemmings

Advertisements
Cleaned, repaired, and reinstalled. There’s no need to abandon a perfectly functional generator.

If you own a car with a generator, odds are somebody has walked up to you at some point while you’ve got the hood open and asked, “You ever think about doing an alternator swap?”

Well, of course you have—every time a car-show or gas-station expert has offered his or her unsolicited wisdom on the state of your car’s electrical system. If you’re like me, the reason you’ve never decided to swap to an alternator boils down to three reasons: 1) the generator works fine with the existing and planned electrical loads of your car; 2) an alternator is really going to harsh the period look of the engine bay; and 3) why change something that doesn’t really need changing?

My 1962 Corvair was designed and built with a generator, and it still has one (although, as I learned, not the one it was born with). Corvairs from 1965 to 1969 came with alternators (“Delcotrons” in period GM speak). Thus, it’s not that hard to put an alternator on an Early Model Corvair, and when one of the ears on the front end frame of the generator broke off this spring, I contemplated it.

This 1962 Spyder, a recent Hemmings Auctions car, has undergone an alternator swap. A fine change, but one that compromises the “1962” character of the engine bay.

The swap would have involved not only a Corvair-style alternator (which rotates in the opposite direction from most and requires at least a special cooling fan and pulley), but the 1965 to 1969 adapter plate to mount it to the 1962 block, a regulator change, and some wiring modifications. But why? I suppose there’s some weight savings (but I’m neither a racer nor that fuel-economy minded), there’s better charging at idle speeds (but I don’t live in the city or do anything where I’m idling a lot), and there’s the potential for increased amperage delivery (like up to 100 amps, but I don’t have any non-stock electrical additions to the car, and the wiring is probably only designed to handle maybe 65 amps anyway).

No, I decided that because my generator had always generated just fine (and, in fact, even once it was flopping around due to the broken ear, though it continued to do its job, just more noisily), I would simply repair the broken ear and reinstall it. Of course, that wasn’t as simple as it sounds.

Initially, I contemplated epoxying the ear back onto the end frame. Candidly, that might have been the best option, but then a friend who is an expert welder said he could stick the metal back together properly for me. That sounded less rinky-dink than epoxy, so I said okay and tore the generator down so I could send just the end plate for repair. Unfortunately, my friend changed jobs and lost a lot of his free time.

On April 21, I discovered that one of the ears had broken off the front (drive) end frame.

Was this Pinin Farina-and-Tom Tjaarda-designed 1960 Corvair Coupe Speciale a foreshadowing of the 1965 model? – David Conwill @Hemmings

Advertisements
The Corvair Coupe Speciale by Pininfarina was a 1960 that was restyled repeatedly in the early ’60s. Image courtesy Gooding & Company.

I’m partial to the styling of the Early Model Corvairs (1960-’64), which is widely known to have inspired the designers who penned the 1961 NSU Prinz. Here’s an example of the other way around. Back in 1960, when the Corvair first came out, someone decided they liked the idea of the air-cooled 80-hp, rear-engine, four-speed, swing-axle Chevy, but didn’t like how much it resembled other Chevrolet products and commissioned Italian coachbuilder Pinin Farina (originally named for founder Battista “Pinin” Farina but styled Pininfarina after 1961) to shroud the European-influenced chassis with Euro-style coachwork.

According to Gooding & Company, who are offering that chassis for sale this month in Monterey, that someone was GM Lead Stylist Bill Mitchell, who was seeking a design proposal. What he got back from Italy was the Coupe Speciale you see here, but not in the form you see it. As it was displayed at the Paris and Turin, Italy motor shows and shown on the March 1961 cover of Road & Track, the Coupe Speciale wore a version of this hardtop styling, but with a much more sloped, Porsche- or Citroën-style nose with single round headlamps. It also still wore ’60 Corvair dog-dish hubcaps on steel wheels.

When it first appeared on the show circuit, the Coupe Speciale still had a Corvair windshield and in its second iteration, wore 1961 Monza wheel covers like the ones illustrated here.

After that first show season, prolific automotive designer Tom Tjaarda was called on the reconfigure the coupe as a 2+2. He also redesigned the car’s rear end in a more angular vein, expanded the side windows, and added the car’s now-characteristic ellipse-shaped headlamp housings. In this form, painted dark green and wearing ’61 Monza wheel covers, it was again on the cover of Road & Track, in February 1963. In a final restyling, sometime thereafter, Tjaarda reconfigured the A-pillars to remove the final visual connection to the early Corvair.

Given the lead times required by production and the nebulous dates connected with some of Tjaarda’s remodeling efforts, it’s hard to say how much the Coupe Speciale influenced the styling of the Late Model (1965-’69) Corvair two-door hardtop versus itself being influenced by the direction Chevrolet stylists were already taking, but the resemblance is clear and the efforts of both the great Pininfarina and the legendary Tom Tjaarda make this one special Corvair.

A Road Racing-Inspired Mid-Engine Corvair? Yes, Please – Mike Austin @Hemmings

Advertisements

The annual SEMA Show encapsulates so many things we love about the car hobby. Heritage, innovation, and craftsmanship are all on display. Take Lonnie Gilbertson’s RareVair, which is headed to this year’s festivities in Las Vegas. It’s a 1965 Chevrolet Corvair Corsa, with a mid-mounted small-block LS, painted to match a unique piece of Chevy road-racing history.

A mid-engine Corvair is not a new idea, of course. Kelmark and Crown made kits, and there are no doubt countless DIY efforts. Gilbertson’s personal introduction to the Corvair happened when his brother bought a Corsa in the 1970s. “That’s when I kind of first became aware of what Corvairs were and I’ve always liked that body style,” he says. “So progress up to now, I was looking around for another project to build, and I thought I’m going to go for a Corvair.”

The inspiration for the car began with the Yenko Stinger. “With the style of that body, it just fit for the sports racer feel about it,” Gilbertson says. Combine that with a 1972 De Tomaso Pantera his shop restored a few years ago and, Gilbertson says, “I’ve always had a thing in the back of my mind about how a mid-engine V-8 car is just a lot of fun to drive. So that combined with the Yenko Stinger and my need for speed, I just thought, I gotta do this.

“After finding a suitable donor car, Gilbertson sourced an LS3 V-8 from a 2009 Corvette. For the gearbox, he went to the 930-generation Porsche 911 Turbo, given its reputation for strength and the fact that the earlier four-speeds have one of the shortest bellhousings. With the gears mounted behind the engine, that means more legroom. “I’m not a small guy,” says Gilbertson, “so I wanted passenger comfort

.”He went to Kennedy Engineered Products to mate the transaxle to the small-block. As for the engine, it had about 30,000 miles on it and looked new inside, so Gilbertson didn’t feel the need to change too much. A Comp Cams camshaft (and associated valvetrain parts) and a Holley Sniper intake are the only changes from stock. Still, he estimates it makes about 500 horsepower at the wheels. Not bad for a car that weighs only about 2800 pounds

The Nut Behind the Wheel: David Conwill can’t stay away from Corvairs – David Conwill @Hemmings

[Editor’s note: The author behind The Nut Behind the Wheel talking about himself? Yes, well, here at Hemmings we’re all a little nuts. Here’s why David Conwill can’t stay away from Corvairs.]“

My parents warned me off from Corvairs when I was still in elementary school. At my bus stop, in kindergarten, there was this fascinating old car. I showed my parents and they said ‘Oh, that’s a Corvair. The heater will asphyxiate you.’ The name Ralph Nader never came up—I don’t think they took him very seriously. They were car people, but Corvairs were just too ‘out there’ for them. It looked so cool to me, though, with that flat roof and wrap-around rear window. I never forgot it. Even once I got into conventional cars, with the engine up front and a radiator, the interesting shape of an early Corvair stuck with me.

“Almost 20 years later, when I was visiting my fiancée, we saw a Corvair convertible coming the other way during a scenic drive we were on. She loved it too and she wound up buying me a couple of old ads that I framed on my wall. One calls Corvair ‘the happiest-driving compact car’ and I think that might be true. It’s not just a shrunken conventional car. That’s one thing that kept me away from them for a long time, but ultimately, that’s a big part of their appeal.

My wife and I bought our 1967 Corvair Monza convertible from the estate of the second owner. The car was being sold by the mechanic on behalf of the wife who was selling all of the her deceased husband’s cars.

The mechanic put me in touch with John, the original owner, who bought the car new in 1967 and he gave me the full history on the car over his 45-year ownership. He bought the car right after he married his wife.

How Frank Winchell defended the Chevrolet Corvair, in his own words – Daniel Strohl @Hemmings

[Editor’s note: While speaking with Nick Gigante regarding his upcoming Corvair Vindication Day event, Nick forwarded us a transcript of the speech that Frank Winchell, his grandfather, gave to 900 or so members of the Corvair Society of America at the club’s annual convention in 1979 in Detroit. We excerpted a few sentences in that story, but thought it worth reprinting here, if for nothing else than for the technical arguments Winchell made in defense of the Corvair.]
Introduction by unknown speaker: I would like to introduce our speaker tonight, Vice President of General Motors Corporations and Director of Engineering Staff, Mr. Frank Winchell.
Mr. Winchell speaking: 
Good evening ladies and gentlemen. It is indeed a pleasure to be here this evening. Everybody always says that… I’ve said it myself. But tonight is different… I mean it!
As a matter of fact, I have addressed very few friendly audiences… period. I don’t address anyone if I don’t have to. I don’t like speaking. I’m not very good at it, it makes me nervous, nobody pays attention and I’m inclined to be a little profane. In fact, I don’t hardly like anyone anymore, anyway—if you want to know… I’m mad.

Smack dab in the middle of America’s heartland there’s now a Corvair Museum honoring the existence and history of Chevrolet’s air-cooled mechanical marvel. The unlikely location for a museum devoted to the Corvair is Decatur, Illinois, which is 40 miles east of Springfield, three hours from Chicago and Indianapolis, and nearly a seven-hour drive from Ypsilanti, Michigan, where it was previously located. But, thanks to the good graces of the Chevrolet Hall of Fame Museum there, a sizeable room has been set aside for the Corvair museum’s new home.
