Giant Killer – Chevron Chevrolet B24 #B24-73-02

Having developed a passion for engineering through his interest in model aeroplanes Lancastrian Derek Bennett took an apprenticeship in mechanical and electrical engineering to become a mechanic, during this time he was exposed to (British) Stock Car racing.

It was not long before Derek graduated into building, maintaining and racing vehicles in the British Clubmans series for small Ford powered vehicles and into Formula Junior.

In 1965 demand for copies of his Clubmans racer led Derek to establish Chevron cars assisted by mechanic Paul Owen based in a former mill in Bolton, well away from the regular stomping ground for racing car manufactured that with few excetions could be found in the arc from Southwest London, round Brooklands and Heathrow Airport to the East and Silverstone to the North.

In 1966 Chevron branched out into building a successful series of up to 2 litre / 122 cui sports cars and in 1967 the company expanded to build it’s first 2nd and 3rd tier open wheelers for Formula 2 and Formula 3.

In 1972 Chevron built it’s first over 2 litre 122 cui open wheeler the 5 litre / 302 cui stock block Chevrolet V8 powered Formula 5000 Chevron B24 which Lancastrian Brian Redman drove in four races, claiming one victory at Oulton Park driving the B24 having won the previous race at Mondello Park a month earlier in a McLaren M10.

Today’s featured car #B24-73-02 was the second built in 1973, third overall from 8 built according to factory records, though as usual this does not tell the whole story, but I’ll be spare you that particular diversion here.

#B24-73-02 appears to have been entered on three occasions carrying the #32 in British races as a factory entered car for Peter Gethin. The first two races held on consecutive days were at Brands Hatch where Peter won the Rothmans Formula 5000 championship round on the cars debut.

The next day the weekends feature event, The Race Of Champions, was a race for contemporary Formula 5000 cars and Formula One cars including entries from Lotus, BRM and McLaren all of whom had won championship Formula One events in the previous 12 months.

Starting 8th on the grid Peter managed to steer his Formula 5000 stock block Chevron to an unlikely victory as his faster Formula One rivals fell by the way side to hold off Denny Hulme in the latest McLaren Cosworth M23 and formula one debutant James Hunt in an ancient Surtees TS9.

There is a myth that this was the only occasion in which a Formula 5000 car beat a Formula One car in such a non championship challenge race, this is not quite true there was a long forgotten event called the 1969 the Madrid Grand Prix at Jarama in which Tony Dean driving BRM #P2615 powered by a V12 BRM was beaten by Keith Holland driving an F5000 Lola T142 and Peter Gethin driving an F5000 MacLaren M10A, but the field at Brands in 1973 was certainly more contemporary and competitive.

Chevron then entered Peter for one more British F5000 race at Mallory Park where Peter finished forth before the car was sold to Douglas Shierson Racing who entered the car carrying the same Marathon sponsorship for Peter in the US L&M series now running the #8 race number.

The B24 did not prove quite so competitive in the 1973 US series where only championship protagonists Brian Redman driving a Lola T330 and Jody Scheckter a Trojan T101 found victory lane. Peters best result came at Lagunna Seca where finished second.

After 1973 #B24-73-02 remained in the USA where, Roger Bighouse 1974 /1975, Pat McGonegle 1976 continued to enter the car in open wheel F5000 events. For 1977 Pat McGonegle converted the car to closed wheel CAN Am 2 spec, scoring a best 6th place finish at Road America in ’77 driving #B24-73-02 which Pat raced until the end of 1978.

Danny Johnson was the next owner and he raced #B24-73-02 sporadically between 1978 and 1982 scoring a best 5th place at Edmonton in 1981.

Similarly intermittently Mike Engstrand drove #B24-73-02 from 1985 to 1987 scoring a best 4th place finish in the cars last in period appearance in the 1987 Canadian American Thundercars Pueblo event.

#B24-73-02 now belongs to Greg Thornton. In 2012 the car caught fire and was badly damaged and it is seen here at Oulton Park after it’s rebuild from the fire damaged remains.

Pressure and Success – BRM Type 25 #258

By 1954 Alfred Owen of the Rubery Owen Group had taken over the running of BRM from the British Motor Racing Research Trust which had been set up nine years earlier to build a British World Beater. The 1.5 litre / 91.5 cui supercharged V16 cars were updated to a short wheel base spec since there were few races for them to compete in that required large capacity fuel tanks necessitated by Championship Grand Prix race distances.

The World Championship started running to 2.5 litre regulations in 1954 and the first two races of the season were won by Juan Manuel Fangio who was entering what turned to be his prime driving a six cylinder Maserati 250F. Fangio then moved as agreed pre season to the Mercedes Benz team who were embarking on their third blitzkrieg on the top echelon of the sport in 60 years. Fangio won the ’54 and ’55 World drivers championships with the German team who successfully applied desmodromic valve and fuel injection technology to their straight eight W196 cars.

Fangio joined Ferrari, who were running V8 powered D50’s gifted from Lancia, in 1956 to win a third straight title and then rejoined Maserati in 1957 to win a forth straight and record fifth title with the Maserati 250F. Fangio retired midway through ’58 and his championship records stood for nearly 50 years until a German called Micheal Schumacher came along and broke them early in the 21st century.

Meanwhile Chez BRM things were progressing at a more leisurely pace a new Type 25 car was being designed with a simple 4 cylinder engine with large valves and an interesting three disc braking system with the rear disc being mounted on the back of the transaxle. Despite being much simpler than the V16 the car did not make it’s first public appearance until September 1955 by which time the Owen Racing Organisation had bought a Maserati 250F and entered it into a couple of World Championship events for Ken Wharton who finished a best 6th in the 1954 Swiss Grand Prix. Peter Collins drove the car in two World Championship events in 1955 but retired from both.

The Type 25’s, chassis type P25 and engine type P27, were supposed make their World Championship debut at the 1956 Monaco Grand Prix but were with drawn after the valves were damaged. Three cars were entered for the 1956 British Grand Prix but none finished however Mike Hawthorn led a BRM 1-2 followed by Tony Brooks for a while before retiring with a suspension problem. Brooks crashed out with a sticking throttle, his car ended up a completely burnt out right off, while Ron Flockhart retired with valve trouble after completing just 2 laps.

The Type 25’s did not appear in the championship again until Monaco in 1957. Nothing substantial was achieved by way of championship results but the Type 25’s did start winning non championship races, Jean Behra scoring the first at Caen.

1958 saw Jean Behra and Harry Schell compete in most of the races with the Type 25. Behra finished a seasons best third in Holland one place behind team mate Schell.

Jo Bonnier replaced Jean Behra who had moved to Ferrari in 1959 and with team owner Alfred Owen having agreed to hand over two cars to the BRP team to run for the remainder of the season prior to the ’59 Dutch Grand Prix the pressure was really on BRM to deliver going into the race. Bonnier arrived at Zandvoort with the disappointment of having almost won the Targa Florio in a Porsche having led most of the way.

The Type 25’s were quick in practice much easier to handle on their 15″ wheels than on the original 16″ with the benefit of much less tyre wear. After a great race with the works rear engined Cooper Climax’s driven by Marsten Gregory, champion elect Jack Brabham and the Rob Walker entered car of Stirling Moss all of whom experienced gearbox issues the smoothly driven BRM Type 25 #258 of Jo Bonnier crossed the line first to win the BRM team’s first Grand Prix 14 years after the team’s announcement in 1945. BRP headed by Stirling Moss’s father offered to reverse the agreement with Alfred Owen and settled for just one car #2510 which they ran in distinctive light green with white wheels livery.

Despite the BRM finishing 3rd in the World Constructors Championship the writing was on the wall that front engined cars were obsolete as the Coopers of Moss and McLaren convincingly won the last three races of the season and Jack Brabham won the first of two consecutive world championships.

Chassis #258 was purchased by Spencer Flack from The Hon. Amschel Rothschild in 2001 for an alleged £1.5 million. The following year while racing the car at Philip Island Spencer sustained fatal head injuries when he was thrown out of it. The car which had split in two and caught fire was rebuilt at the insistence of his widow and now belongs to John Pearson who is seen at the wheel in these photo’s taken at last years BRM Day.

Move Over – Rover P6… Cabriolet !

The other day I was ambling along to the shops in the bright sunshine and I caught a glimpse of an old school chrome bumper through a hedge, it was attached to a Rover P6 (marketed as a Rover 2000) I didn’t think much of it till I got around the corner and it registered there was something odd, the roof was missing.

I went back to check and sure enough this is a Rover 2000 4 door cabriolet. I have no idea where or when the conversion was done, probably when the car was at least 12 months old to avoid attracting additional car purchase tax.

The Rover P6 Series 1 was in production from 1963 – 1973. This particular model was relatively underpowered by a 104 hp single carb, 1978 cc 120 CUI Heronhead (flat head / combustion chamber in the piston) overhead cam four cylinder engine. 208, 875 examples were produced of which between 160 to 170 are thought to have been converted post registration (to avoid additional car purchase tax) into estate / station wagon types by HR Owen and Crayford Engineering. Crayford are well known for Cabriolet conversions and possibly may have done this one.

If you know anything about Convertible P6’s please tell us about them ?

Slightly off topic tonight (UK time) is the night Happy Harvick and anyone else interested in lifting the NEXTEL CUP surely has to beat Jimmy Johnson to be considered a contender, if the #48 leaves California with the win then I’d say the Chase and the Drive for Five is all over bar the shouting. Fingers crossed Go Happy ! Go Harvick ! Go #29 !

Wishing everybody a sunny Sunday. Don’t forget to come back know !
