Spoiler Homologation Special – AMC Javelin SST Mark Donohue Edition

The AMC Javelin was AMC’s iron in the Pony Car fire to compete against the Mustang, Cougar, Camaro, Firebird and the last entries into the Pony market segment the Dodge Challenger and Plymouth Barracuda on offer from the big three in Detroit, it was styled and developed by Richard A Teague and launched in 1968.

Short of resources the Javelin was developed from the 1966 AMX and AMX II concept cars and only offered with the two door semi fast back body style powered by one of three engine options all of which could be specified to burn either regular octane or premium octane fuel.

Despite not having a competition department, any technical support, performance parts or even a test facility of any kind AMC approached Ron Kaplan and Jim Jeffords of Kaplan Engineering to run two Javelins in the SCCA Trans Am series, in 1968.

The team with drivers George Follmer and Peter Revson who got replaced half way through the season by Lothar Motschenbacher finished a commendable 3rd with an enviable record for getting their cars to the finish.

Kaplan ran the team again in 1969 with Ron Grable and John Martin who like Revson was replaced mid season by Jerry Grant, things between AMC were not so smooth second time round which was compounded by budget cuts that saw Kaplan take all of AMC’s inventory from their workshop to AMC’s zone office in El Segundo, California at the end of the season.

AMC did a deal with Roger Penske for the 1970 season who with the aid of Mark Donohue picked up the pieces and developed them in Pennsylvania into a more competitive package.

In order to run with the duck tail spoiler Mark had developed for the Trans Am race programme AMC built 2,501 Javelin SST Mark Donohue Editions that included the spoiler, a 5.9 litre / 360 cui motor and a variety of other options that makes these cars easy to replicate and difficult to verify in the absence of a specific vehicle identification code.

Mark was joined by Peter Revson and the team finished 2nd to Bud Moore’s Ford team in the 1970 Championship, before going on to win both the 1971 and ’72 Trans Am championships with the second generation Javelin.

Today’s featured 1970 Mark Donohue edition belongs to Klass Van Dijk who was so impressed with a 1974 AMC Gremlin he bought in the 1990’s that he founded the Rambler AMC Museum in Berlikum, Holland which now houses more than 50 AMC’s, a small collection of Chevrolet Corvair’s of the type his father drove and an eclectic mix of other vehicles.

Birdcage Streamliner – Maserati Tipo 60 #2451

Despite winning the 1957 World Championship Drivers Title, there was no constructors title until 1958, with Juan Manuel Fangio, Maserati was in dire financial trouble at the end of the year and after four sports car were written off in South America the Italian Government had to step in as receiver to save the company.

Immediately all motor racing programmes run by the factory were cancelled, but just one year later the case was made for Maserati to resume building racing cars so long as they were paid for and raced by customers.

Engineer Gulio Alfieri was given a brief was to build a low cost, competitive, two seater racer, using existing parts stock where possible.

In the absence of sufficient contacts to help him build a monocoque chassis Alfiei devised a space frame Tipo 60 chassis built up from thin tubes with a 2 litre / 122cui 4 cylinder motor that became known as the ‘Birdcage’.

Today’s featured chassis #2451 started life as the prototype Tipo 60 and on the 12th of July 1959 it was driven to a win in the Rouen Grand Prix by Stirling Moss.

Stirling Moss is said to have been impressed with the ‘rightness’ of the design, the light but precise steering, the totally neutral handling characteristics with the superb brakes also being singled out for praise.

Italian hillclimb specialist Odoardo Govoni then drove #2451 to a win on the ‘Pontedecimo-Giovi’ hillclimb on the 20th September 1959, soundly beating the favourite Giorgio Scarlatti’s Ferrari Dino 196S.

Maserati chairman Omer Orsi authorised the production of six Tipo 60 chassis and it was not long before requests from the US came in for cars fitted with 3 litre / 183 cui motors.

Subsequently Alferi was asked to work on a 3 litre motor and he managed to squeeze one into a Tipo 60 which which then became the Tipo 61 to distinguish the larger engine size.

In September 1959 Lloyd Perry ‘Lucky’ Crasner tested a Tipo 60 and immediately ordered two 3 litre cars for his CA-sner MO-tor RA-cinq DI-vision, better known as the Camoradi Racing Team.

A shortfall in manufacturing capacity left Maserati no alternative but to fit a 4 cylinder 3 litre / 193 cui motor to the prototype chassis #2451 which was then shipped out to Nassau in December 1959 for Dan Gurney, Carroll Shelby and Jo Bonnier to test in preparation for the Nassau Speedweek.

Dan claimed a class victory in the Preliminary Governor’s Trophy while Carrol retired from the Nassau Trophy Race after a puncture and then an accident.

Dan and Marsten Gregory qualified #2451 2nd for the 1960 1000kms at Buenos Aires but retired with a broken shock absorber mounting bolt after leading comfortably.

Carroll Shelby teamed up with Masten to drive #2451 in the Sebring 12 hours but retired with an engine issue.

At the Targa Florio #2451 was entered for Umberto Maglioli and Nino Vaccarella who led the race at 3/4 distance only to crash after a rock punctured the fuel tank.

During the subsequent repairs #2451 had a new streamline tail added along with the extreme screen which was designed to meet the Le Mans minimum height screen regulations and minimise the frontal area of the car. The other 2 Camoradi T61’s had the modified tail fitted for Le Mans, but not the low frontal area screen.

#2451 was the fastest car at Le Mans in 1960, after a starting problem saw Marsten cross the start line in 24th place he had recovered the lead by the Mulsanne Corner on the opening lap overtaking 18 vehicles on the Mulsanne Straight.

After a couple of hours Marsten handed #2451 over to Chuck Daigh but the car lost an hour with another starter problem. Between the forth and eighth hours Marsten and Chuck had recovered two of their lost laps, but at midnight the car was retired either with a blown motor or an electrical issue depending on which sources one reads.

The Le Mans race was the last race of the 1960 World Sportscar Championship season and #2451 was chosen by Camoradi backer Frank Harrison as the car he was promised and wanted to run in the USA.

Harrison entered the car for Jim Jeffords who won with it at Road America on July 31st, 1960. In April 1961 Fred Gamble drove #2451 to a class victory at Marlboro .

Sources are not conclusive on #2451 being the car that William Kimberly drove to victory for Frank Harrison at Courtland in July 1961.

Frank sold #2451 to Don Skogmo, a regular winner aboard a Maserati Tipo 61, who is thought never to have raced #2451.

In 1971 #2451 found a new lease of life in the British ‘JCB’ historic championship where it was driven to a championship victory by Brian Joscelyne.

By 1980 #2451 was to be found in the Rosso Bianco collection belonging to Peter Kaus. Today the car, which was first registered for UK road use in 2010, is owned by Windpower magnate and Maserati Collector Willi Balz who is seen at the wheel at Goodwood a couple of years ago.

Thanks for joining me on this “Birdcage Streamliner” edition of “Gettin’ a li’l psycho on tyres”, I hope you will join me again tomorrow when I’ll be looking at a versatile Talbot that raced at Le Mans in 1939. Don’t forget to come back now !

FI = 1 H.P. per CU. IN. x 283 – Chevrolet Corvette C1

With the arrival of the enthusiastic Zora Arkus-Duntov in GM’s engineering department, the famous Chevrolet small block in the engine bay and some competition in the form of the Ford Thunderbird, Chevrolet ramped up it’s commitment to building and American sports car in 1956 by replacing the first iteration of the Corvette which was considered low on performance, high on water leaks into the cockpit and less than a true sports car.

Banished for ever in 1956 was the 155 hp triple carburetor Blue Flame six cylinder engine, the Corvette from 1956 on was strictly a V8 powered vehicle.

For ’56 there was all new bodywork, replacing the first generations body that was close to the original concept Corvette first seen in 1953.

The bold sculpted sides behind the front wheels really helped the second iteration two tone Corvette stand out from the crowd.

As did the faux air scoops on the front wing/fender.

There was a hard top hood option and the much improved soft top had a power assisted option as did the roll up glass window’s.

The three speed manual transmission became standard but the, inferior performance wise, Powerglide automatic remained an option. The cockpit controls fittings and instrumentation of the ’56 and ’57 ‘vettes remained similar to the original Corvette cockpit.

Following in the footsteps of 1953 Gutbrod and the 1954 Mercedes Benz 300SL in 1957 the GM Rochester constant flow fuel injection was an option for the Corvettes small block V8. This innovation while not widely taken up, 1040 FI units were sold, took the power up to 290 hp, however for marketing purposes the car was said to have 1 hp for every one of of the small block V8’s 283 cubic inches.

Thanks to Zora Arkus-Duntov ’57 Corvettes could be ordered with ready to race options including the fuel injection, heavy duty suspension and if the advertising is to be believed even the power windows were said to be lighter than the manual window mechanisms.

Among the race outright Corvette winners in 1956 were Bob Stonedale, Mansfield, Bark Henry, Road America, Bill Pollack, Buchanan Field, Robert Bennet, Mansfield and most successful of all in ’56 was Dick Thompson who won at Beverly, Seafair, Thompson CT, and Palm Springs.

In 1957 Corvette drivers winning outright are known to have included Ruben Ciriacks and Peter Talbot at Hawaii, Ned Yarter at Willow Springs and Bakersfield, Jerry Parsons at Smartt Field, Bob Drake, Santa Barbra, Dick Thompson, Cumberland, Eagle Mountain, Marlboro, Viginia, Road America, Bob Byrd, John Masterson and Lloyd Gray at Cotati, Jim Jeffords, Milwaukee, Lloyd Porter at Bakersfield, Bark Henry, Lime Rock and Montgomery, Dean McCarthy, Watkins Glen, Jerry Austin, Pomona, Santa Barbra, Riverside, Palm Springs and Paramount Ranch, Bob Bent Cotati and Arcata, Leonard Butscher, Thompson CT, Fred Windridge, Watkins Glen and Bridgehampton, Dan Gurney at Riverside, John Wood, Willow Springs, H. C. Hoppe (Ladies Races) Bakersfield, Willow Springs and Orange County, Hugh Woods and Cal Bailey at Hourglass Field, Jack Bates and Frank Cairns at Pomona, John Voevodsky and Bill Moore at Phoenix and finally Elgin Holmes who won at Willow Springs and Orange County.

With Duntov’s vision the American sports car had finally arrived.
