Big Block Pagoda – Iso Grifo Super 7 Litri Series I

Iso Rivolta was the brainchild of Italian Engineer Renzo Rivolta who had been responsible for Isothermos refrigeration units prior to World War 2.

Wishing to move into motorised transport markets Rivolta developed a range of expensive but well built durable motorcycles from 1948 to 1961.

In 1950’s Renzo developed his best known vehicle the Isetta Bubble Car that was manufactured by Iso in Italy and under licence by Velam in France, Romi in Brazil and most successfully by BMW in Germany.

After leaving Ferrari in 1961, where he had been responsible for the fabled Ferrari 250 GTO, Giotto Bizzarrini set up his own design studio and in 1963 designed the mechanical architecture of the Iso Griffo A3/L. The Grifo,launched in 1963, featured a blueprinted, a process of disassembling a motor then rebuilding it with all the engine parts matching the exact original engine blueprint design specifications for optimal performance, 400 horsepower small block Chevrolet motor.

In 1968 the Grifo was made available with a 435 hp Chevrolet 427 big block motor, requiring the pagoda like air scoop on the bonnet to accommodate the extra height of the larger engine,

along with extra ventilation in the front wings to keep the motor cool, seen on this vehicle which was built in 1969.

The Grifo 7 Litri was said to be capable of 186 mph.

It would appear that just 67 of the 7 Litri Series I vehicles were produced from 1968 to 1970 when the rarer Series II Grifo’s with pop up head light covers were introduced.

The combination of rarity, Bertone styled beauty and mechanical simplicity, a result of using many proprietary parts including the engine and gearbox, makes the Grifo a relatively easy to maintain collectible car.

Racing Maloo – HSV Maloo

2 Replies

Two weeks after starting the ‘Gettin’ a lil’ psycho on tyres’ blog I remember getting a huge thrill from discovering an HSV Maloo on the streets of Bristol and learning that it was the fastest pickup truck in the world.

Last weekend while at the Britcar British Endurance Championship Racing Weekend at Castle Combe I stumbled across another Maloo this time in full race trim including

slick tyres to compliment it’s 400 hp Corvette LS2 engine which according to one passer by in a Britcar T shirt is tuned to 600 hp good for reaching 60 mph in under 4 seconds.

When I got home I was surprised to learn that there is an Australian racing series for Ford and Holden pick ups, where pickups are known as Utes, which is part of a staircase to find talent for the top tier Australian V8 Supercar series.

Even more surprisingly I have found out that late last year an announcement was made by Britcar to the effect that they would organise a debut season for a UK V8Ute Series using only the rebranded Vauxhall VXR Maloo pickup model.

The cars were to be rented from Britcar with the rental cost including entry fees for a full season of races.

The plan was that at each meeting the Maloo’s would take part in three 40 minute races with mandatory pit stops for driver changes.

The projected series is on temporary hold, I look forward to an announcement from Britcar that the series will get a chance to go public and from Vauxhall that the VXR Maloo gets the opportunity to enter the UK market place.

Racin’ & Rockin’ – #46 Hunter Brothers Chevrolet Impala

6 Replies

For those needing a NASCAR fix while the series is taking a break today’s car is the #46 Hunter Brothers Chevrolet Impala, seen here at Palo Alto earlier this year, that operated out of Hendersonville NC in 1965.

This car was driven by US Airforce Sergeant Roy Mayne, from Sumter SC who was given permission to race while on active duty. His best finish was in 1965 when he drove this car to a 4th place finish behind Ned Jarret, Buck Baker and Darel Dieringer in the September 6th Southern 500 at Darlington.

From 1963 to 1974 Roy drove in 139 Grand National and Winston Cup events scoring 22 top ten finishes. He never compete in a whole season his best end of season standing was 25th in 1966. Roy was one of the stunt drivers in the 1968 Elvis Presley movie ‘Speedway‘.

The new for ’65 fourth generation Chevrolet Impala set the all time industry annual sales record of more than one million units sold. Chevrolet finished 3rd in the final standings of the 1965 Grand National season behind Ford and Dodge.

My thanks to Geoffrey Horton for sending me the photos.

Wishing all my fellow NASCAR fans a relaxing day off, see you all at Rowdy Chat for the Brickyard 400 next Sunday.

The Super Hugger – AJ Rivers Simoniz Chevrolet Camaro Z28 Replica

1 Reply

While I was whizzing up to Castle Combe in the teaming rain a couple of weeks ago, I went flying past a rumbling cloud of spray that turned out to be this Chevrolet Camaro like the one once owned by former saloon car driver and race team owner Richard Lloyd.

It turns out the wide tyres were having trouble cutting through the water lying on the motorway and the Chevy was aquaplaning at speeds far lower than those I was travelling at in my borrowed Kia Picante with skinny tyres.

This is an early second generation 1970 Camaro,

fitted with a 5700cc / 350 cui V8 rated at 360 hp as part of the

Z28 performance package, a peak in the story of muscle car performance which with the onset of the 1973 fuel crisis would never be matched in the remainder of the 20th century.

The Chevrolet Camaro Z28 had a successful career in British Saloon Car racing, Frank Gardner used one to win the 1973 British Saloon car championship outright.

For 1974 the British Saloon Car Championship was open to vehicles in a much lower state of tune known as Group 1 regulations and several Camaro’s and one Plymouth Barracuda fought for top class honours, some of the Chevy’s including one run by Richard Lloyd, if I remember correctly, ran with either a 7 litre / 427 cui or a 7.4 litre 451 cui motor.

Back in 1973 while Richard was still running his car with a 5.7 litre / 350 cui motor he was scheduled to run in an event called the Avon Tour of Britain, that went round the entire country taking in races at many of the best circuits, rally stages and even a drag strip.

Richard fell ill prior to the event so he drafted in his team mate from the Spa 24 hours, up and coming British Grand Prix driver, James Hunt into the Simoniz Camaro at the last minute, James promptly ended up walking away with the victors trophy.

The car seen here is a replica of Richard’s AJ Rivers entered car that was built up for the 2005 Tour Britannia a mini Avon Tour of Britain for mostly historic vehicles.

Richard and his former entrant Alan Rivers competed in the Tour Britania from 2005 – 2007, but in 2008 Richard lost his life in a tragic plane crash that claimed the lives of several other well known figures from British Motorsport.

In memory of his friend Alan Rivers used the car one last time in the 2008 Tour Britania, before it was acquired by Stuart Scott and Steve Wood.

Stuart and Steve have entered this vehicle in every Tour Britannia since,

clocking class wins in 2010 and 2011.

Stuart hopes to take the Camaro to the Historic Festival at Lime Rock CT in September.

Exploring The Limits Of Handling and Performance – Chevrolet Corvette Stingray Concept Car (Replica)

2 Replies

The 1959 Chevrolet Corvette Stingray concept car was based on the tubular steel chassis 1957 Corvette SS racing car that was abandoned after the 1957 Sebring 12 hours as a result of an agreement between members of the Automobile Manufacturers Association (AMA) not to build factory developed racing cars.

Vice President of GM Styling William (Bill) L Mitchell is credited with designing and building the Stingray Concept Car featuring a fibreglass body which weighed in at 2,200 lbs around 1,000 lbs lighter than a contemporary production Corvette.

The one off concept was entered by Bill in numerous races from at least April 1959 to at least October 1960 mostly for Dick Thompson and a couple of races for John Fitch, by early 1960 Dick had clocked up several class BM wins.

Powered originally by a fuel injected 4.6 litre / 283 cui which was good for 315 hp at 6,200 rpm the car was used as a test bed for a four speed manual transmission once it’s racing days were over. Today the car which resides General Motors Design Center has a 375 hp 5.5 litre / 327 cui motor fitted.

Styling of the Stingray Concept Car heavily influenced the styling of 1963 Chevrolet Corvette Stingray production car. The strong line around the mid rift would become a feature on many vehicles of the 1960’s the Chevrolet Corvair, Alfa Romeo GTV 2000, almost the entire 1960’s BMW range, the Hillman Imp / Singer Chamoise and NSU Prinz to name but a few.

This particular replica which I have seen at Silverstone many times over the years appears to be based on a 1977 Chevrolet (Corvette ?) chassis and is powered by a 5.4 litre 283 cui engine.

50 Foot Special – Mercedes Chevy 300SL

6 Replies

Back in the 1950’s US Mercedes Benz importer Max Hoffman is credited with encouraging Daimler Benz AG to build the Mercedes 300 SL (W198) based on the successful 1952 Le Mans Winning 300 SL (W194).

Chuck Porter amongst a few other US racing drivers took wrecked 300 SLs and turned them into full blown race cars giving them the ‘SLS’ moniker.

The body of today’s car owned by multi championship winning driver and owner Dave Wolin is thought to have possibly started as such a project. The body is said to have been abandoned in a San Gabriel Valley back yard for 50 years after incurring the legal wrath of Daimer Benz AG for being too close a copy of the original.

When Dave found the body it had a tree growing in it ! After the body was rejuvenated it was fitted to a modern chassis powered by a Chevrolet small block crate motor. The power is transmitted through a four speed Richmond T 10 gearbox and Speedway Engineering Quick Change rear axle.

Dave successfully competes with this cool car in races, hill climbs and surprisingly, given that he modestly calls his Merc a 50 Footer*, also enters his Mercedes into Concours events such as the Sacramento State Capital Concours as seen here.

* Looks good from 50 feet but it’s a racing car not a show car.

My thanks to Geoffrey Horton for the photos, for introducing me to Dave Wolin and to Dave for the additional photos and information about this ultra cool 300 SL.

Ian vs Danny – Tour Britannia Castle Combe

5 Replies

Back in 1973 a multidisciplinary event was organised that brought together the world of racing and rallying called the Avon (tyres not cosmetics) Tour of Britain in which competitors took part in a wide range of production (safety modified only) vehicles in a wide range of race, rally and even drag events across the length and breadth of Great Britain.

On Saturday Tour Britannia a similarly organised event for historic, classic & modern vehicles based this year in Wales and South West England visited Castle Combe on Saturday morning, when the race track was used as a rally stage thanks to the addition of three temporary chicanes and in the afternoon as a more conventional race track.

Headlining the racing fraternity on the inaugural event in 1973 were former two time Grand Prix World Champion Graham Hill in a Datsun Bluebird, regular Grand Prix participant Howden Ganley in a Citroen XM, similar to the #29 US spec vehicle of Andrew Brodie and Robert Lowdell above

and future world champion in his rookie year making a big name for himself James Hunt in a Chevrolet Camaro belonging to the injured Richard Lloyd, similar to the vehicle of Stuart Scott and Steven Wood above which Richard Lloyd recreated in 2005 shortly before his untimely death. James in the Camaro was the winner of the inaugural event in 1973. Scott and Wood were awarded the Competitors Choice Concours award.

The following year the publicity generated by the event in 1973 galvanised Ford into preparing two Escort RS2000’s for British UK Rally Champion Roger Clark and Saloon Car Racing Champion Gerry Marshall that were inseparable for most of the races with Roger pipping Gerry to the post in the final standings. Though in far higher states of tune than the original 1974 Escorts the vehicles of Phil & Mick Squires left and David Smithes & Eric Woolley right provided an evocative reminder of the epic battle in 1974. Phil & Mick won their class in this years event.

The highlight of the two races held on Saturday was the drive of former British Formula 5000 champion Ian Ashley in his Caterham R500 from the back of the grid to the lead in just two laps, above the ever on form Ashley is seen lining up the leading Porsche 911 RSR before the completion of the second lap.

the #42 Porsche was driven by another name driver,

no less a name than former New York City cab driver, 1985 Indy 500 winner and 1988 Indycar Champion Daniel John ‘Danny’ Sullivan III from Louisville Kentucky ! Danny won his class in this years Tour Britannia which finished at Silverstone, yesterday afternoon.

My thanks to Simon Lewis who’s heavily discounted ticket allowed me to visit this event.
