John,
There are various bits of info on :
http://www.70sroadsports.com/
and
http://www.hscc.org.uk/
Here is a Cut and Paste from the above:
The 70s Road sports championship was initiated by the HSCC for the 1994 season and was born out of the highly successful Historic Road Sports Championship for 1950s and 60s cars with very similar regulations. From the very start the aim was to provide a relatively cheap entry to historic motorsport with the major bonus that 70s sportscars are in the main both cheaper and more plentiful than their 60s equivalents. The HSCC has always been a novice-friendly club and 70s particularly so, with plenty of help and advice available from the championship chairman, registrar and club office. Most proper production sports cars registered between January 1st 1970 to December 31st 1979 will be accepted into the Championship.
As the title suggests the Championship is for road going cars, which can be driven to and from race meetings thus recreating the spirit of the 60s/70s and saving the cost of trailers and tow cars. Road driving your car is not obligatory however, but you forfeit the 2 championship points awarded to drivers who drive to every round.
The Championship Regulations set down the rules and modifications allowed for all cars. Great attention has been paid to keeping costs down and in broad terms cars must remain in close to standard form although road springs, dampers and brake pads for example can all be changed for up-rated items. Limited engine tuning is allowed but the retention of standard carburation and banning of steel crankshafts, for example, limits expenditure on engine preparation. Each car must comply with its detailed Vehicle Identity Form signed off by the Registrar before it can race and random checks are carried out during the season to ensure fairness for everyone.
Cars are divided into various classes:- Class A all cars over 3 litres; Class B all cars between 2 and 3 litres, Class C fibreglass bodied cars 1.3 - 2 litres, Class D metal bodied cars 1.3 – 2 litres. Class E all cars up to 1.3 litres, Class F all Lotus 7s, Class G Invitation Class. The overall championship is won by the driver with the most points in class, which means a good driver in a relatively inexpensive car can still take the overall award. A Lancia Beta Coupe and Triumph GT6 from class D have won 3 championships in seven years between them for example. Grids have built up very well over the years with a wonderful diversity of different models. There is always very close competition for both class and overall honours.
Historic racing does not generally attract overly aggressive drivers. Most competitors are, after all, racing a model that they are fond of and have no wish to damage. However, the 70s Championship committee keeps any eye on driving standards and are prepared to take firm action with any transgressors, to protect the friendly atmosphere that has typified the Championship from the beginning.
If the idea of competing in 70s Roadsports appeals to you call or email the club office or Championship Chairman Richard Thorne for a chat. He will know of any suitable already prepared cars available or suggest specialists who can prepare your existing road car.
