The specifications were all mixed up and mostly not as recorded at Abingdon. These cars were mostly fitted with very late engines, all were fitted with additional aluminium plates on the bulkhead, either stamped '8.3 pistons fitted' or '1750 cc Exp AEH ???, gasket No AEH ???' (I'll try to find the photos). It is believed that 4 of the engines were 1762cc. Rodney Green has kept one of the original pistons marked Mowog. I have confirmed at least 3 engines, which still exist - these are some of the very last engines built.

I owned this car for a while, but it was running on an MGB unit. The car was sold to Rodney Green and then to Dennis Bron in Holland a few years ago, together with the engine 2261, and was raced very successfully at Silverstone in 2005

The engine went to YDH5 1827, raced by John Gommershall and Clive Alexander and later bought by Alan Green, and the engine is still in the car.

Many Twin cams have since been converted to 1762 cc, including Rodney's extensively and successfully raced YD2 2597, and YD2 2600, which was also with me some years ago - a very fast car built by Roger Pearce, twin 40 webers etc. The question is - how many other cars were converted to 1762 cc using factory kits? (besides SRX 210 and Bobby Olthoff's YDH5 929, converted later at Abingdon). Incidentally, I have YDH5 928 in my garage, used on weekends, showing evidence of competition use (most engine nuts and bolts wired, bolted and removable LHS engine mount, CRG), but no specific competition records."
