I was thinking only of standard Repco capacities.

I'm inclining more towards 1972, Steve. Here's a photo of the car from 1973:

and the rear wing looks very different. The mystery photo looks much more like the car was in 1972 (when it also carried #3). I also don't think it's MacDowel; all photos I've found of him in the car show him wearing a full-face helmet (although not always with the white stripe). To me it looks much more like Tony Griffiths, who shared the car with MacDowel at the Prescott event of 7th May 1972 after his own Repco-engined Brabham had cam drive problems.
In the original photo the car appears to be running as #3 so I wouid have thought unlikely to be anyone other than MacDowell.

Of course, as time went by stroke:bore ratios did reduce. The 1984 Renault had a stroke just half the bore. Nowadays, sadly, it's whatever the regulations say it has to be.

John McCormack related to me that Phil Irving told him that the pistons in the 740 engine he had were just 'fluttering about in there' or something similar.
Taking the engine out to 4.4-litres was, as I understand it, going as far as the original block could be safely be taken. It was after casting their own blocks that Repco went to 5-litres.
