I took this photograph at Brittens chicane during the AMOC Intermarque Championship race at the Aston Martin Owners Club's meeting at Oulton Park in May 2017.
It's David Falkingham in his 1979 Triumph TR7, which according to the programme of the event had a 4.6 litre engine. The TR7 was introduced in 1974 and had a 1,998cc 4-cylinder inline engine and this car morphed into the TR8 with a 3,528cc V8 engine. Presumably David Falkingham's car has the later Rover 4,552cc V8 engine.
