I hadnt read it but I am sure the Duke is onto something, when they had the Mk 1 Lotus Cortina race a year or two back the modifications where so wild as to be externally visible never mind what had been done under the bonnet. This does a disservice to all classic racing creating effectively silhouette racers that only resembled the actual 60's cars , and yes I am looking at you Austin A40 Farinas and the big Austin that Karun was driving last year , in reality in the 60's these would not hold a candle to an Alfa Giulietta under top speed or braking. (yes I was a long term Alfisti)
