The Ford GT40 Roadster

They existed but they were rarely a winner….

by Wallace Wyss –

Most people know the Ford GT40 as a coupe but I’m here to tell you that there were in fact factory-built Ford GT40 roadsters. We haven’t been able to confirm how many, most say five 108; 109; 111 and 112 – all small block 289-powered versions. Actually there was a big block version, SN110; the aluminum-chassied version that won the Sebring 12-hour in ’66 with a GT40 Mk II nose and rear body section with a fastback roof, not the “targa” roof that was used on the small blocks.

That same car had earlier been a Can Am car, the GTX-1, nicknamed “Big Ed.” It was singularly unsuccessful in Can Am, even with the likes of Bruce McLaren working as development engineer and as part time driver (along with Chris Amon).

That car in fact won the biggest victory for the open GT40 genre, being a winner at Sebring in ’66, only to be rewarded with a trip to a landfill later. (We know the town it was reportedly interred in, but finding it would be an exercise to tax present-day treasure-hunting technology.)

There were actually two aluminum-chassied GT40 chassis made for big blocks but the second one was either built into a coupe or is still floating around depending on which hoary old rumor you want to believe.

Apparently Ford built some small block GT40s in roadster form just out of curiosity. The coupes were beastly inside on a hot day, and at the time Ford thought perhaps an open version would be easier for the drivers because of that. Or maybe it was just because. Ferrari had open cars like the 250P, so Ford figured “If we’re gonna copy Ferrari, let’s copy everything.”

Ford then built four with the small block 289, but they weren’t any faster, and you had to admit, during those 24 hour races at LeMans there was always rain and a wet driver was distracted compared to a dry one. One would think the coupe version would be more rigid, with less flex to the body and hence able to hold the line better through a corner. There was no temporary top you could put in place in the GT40 roadsters, though sometimes coupe owners ran their cars without the top half of the doors (which were part of the roof as well), so they were in effect T-top coupes.

The story of what happened to the roadsters is still occupying historians today. One of the roadsters (the green one that Bondurant flipped on its side in the Targa Florio in ’65) was discovered cut in half in a breaker’s yard in England a few years back. Bought as-is, the two halves were welded back together and rebodied with a new body cast from a real original body found in storage in South Africa. It has since raced in the Goodwood events, where it’s every appearance causes embarrassment for those GT40 historians who had published books years earlier listing it as “destroyed” or “written off.” It was put up for auction in 2011 but was a no-sale.

Another resurfaced more recently in the estate of Dean Jeffries, a Hollywood stuntman who died a few years ago at the age of 80. He was given the car for free by Ford because they mistakenly thought he could get it in a movie. He was a stuntman as well as customizer, but never quite got the car done, spending some three decades and more installing a four cam Ford V8 to prove Ford should have run that engine instead of the pushrod.

The GT40 roadster inspired the GTX-1 version of the ’05-’06 Ford GT, a conversion done by a private firm in Wisconsin on privately-owned GT40s, but done to a Ford engineer’s design.

If Ford does another take-off on the GT40, let’s hope this time they make an open version as well as a coupe so they can be assured the program will be completed. (The aftermarket firm that was making the GTX versions seem to have lost interest in the conversions.)

How much are they worth? RM-Sotheby’s sold theirs for close to $6,000,000 in 2014. I’d argue that they ought to be worth $10 million except that only one of the five small block targas actually raced at LeMans (in 1965). But I’d say that’s quite a name to drop when you own a race car….

Let us know what you think in the Comments.

  1. mark nolan says

    awesome info.
    historians and the like. amazing things.

    i remember a local engineer petrol head in 70,s here in uk driving a kamm tail gt40 on the road with straight pipes. lathe swarfe in the footwells always..

    finding two pieces of chassis..didnt sell…goodwood eligible …..its the uk old boy network. the world would not be buyers of a wrongun.
    in uk…the government agency give owners clubs permission to stamp their own data to obtain title..making the owners club data Representative god like and most of time scum who collects titles.
    years ago lola where needing funds..i asked eric why he didnt build a few missing T70 and sell them..he advised as the owner and manufacture he could…but eric you own lola…..advised there was a data historian in sweden who had info on every T70 and more. BEYOND.

  2. Jim Smith says

    The ex-Dean Jeffries car was a no-sale at Mecum Kissimmee back in January at $10M

  3. wallace wyss says

    Regarding T70 I was going to review a book on them, very well written but when I reached the tenth mention of making a new tub I threw the book away because to me the only real car is the real chassis, not a re-chassied car.

  4. Glenn Krasner says

    There IS a 2019 Ford GT40 with a twin-turbocharged V6 engine. It has been out for a while, and all the car magazines road-tested it. Glenn in the Bronx, NY.

  5. Great to find such Car existed long ago while back to the market in a modern pattern with turbo brand.

    Lovely and thanks.

  6. wallace wyss says

    The 2019 is called the Ford GT and not GT40 because Ford didn’t read the fine print when they sold an English company the rights to make continuation GT40s. I don’t consider it a GT40 successor because it has a V6 and is ugly, and now that the 2020 Corvette is introduced, at a fraction of the price, the Ford GT has no reason for being.

  7. Craig Libuse says

    I took a photo at turn 6 at Riverside of the #71 X-1 in action in 1966. Also a couple of shots of a white roadster also at turn 6 the previous year, 1965. I am attempting to download them, but I don’t see anything happening. Sorry if they don’t show up.

  8. Craig Libuse says

    I’ll try again with the #71 shot…apparently the site only downloads the last selected photo.

  9. Craig Libuse says

    Sorry, the white roadster with full windshield and just marked “FORD” was from 1966, the #71 car was shot in 1965. I reversed the dates.

  10. wallace wyss says

    The one with no number on the side is a regular small block GT40 roadster.The one with the number 71 is the big block known as Big Ed, raced by Bruce McLaren in Can Am with Ford’s blessing, But it was ill suitrd to short courses. It was repainted red, entered at Sebring and won and was buried lest some amateur get hold of it and get killed beaue it ws falling apart. So it was off ptting to me to see a look-alike rcing at Monterey in the Rolex Refival and displayed at LaJolla. Too bad I can’t go back and ask Steele Therkelson if he ever heard it was dug up. Steele was there when Shelby ordered in interred, Steele has since died.
