"At this point a slight diversion is necessary because in the early 1970s a couple of 4 valve V12s were built, one for road use, the other as a potential race unit.

These were modern narrow valve angle designs and the race version was soon developed to produce a very impressive 630 b.h.p. from 5.3 litres using a standard crankshaft.

The one and only prototype was loaned to TWR in the 1980s for them to study prior to producing their own 4 valver.

Unbelievably, after they had stripped it and looked it over they threw it in a skip.

One has to wonder if there is a scrap man somewhere who recognised what it was and saved it from the furnace.

If so, perhaps it may yet turn up but what value would be placed on such an engine now?"

Allen Collins, who worked at Lister Jaguar and made 7Litre crankshafts for the XJS Racing Cars - Le Mans TWR (Wilkenshaw Racing) came out from England to Australia and was very excited about the specially made heads.
