I think with the ex Stillwell Cooper Monaco it had both the Buick V8 and then received the Oldsmobile V8 when with Tony Osborne in 1966. In event programmes when entered by Bib Stillwell (in V8 form) it's usually listed with a capacity of 3900cc (ex Daigh Scarab/Glass BRM). In the June 66 Sandown programme the capacity for Tony's car is listed at 4400cc and kept growing afterwards.

I'm not up with what the FIA would allow as far as Steve's question on whether it would be eligible to run with a V8 in historics. I suspect not though.

What better than if Ellis can get Geoff Smedley to share his wisdom on the Matich Lotus. I have a mention of it being the July 1965 Lakeside meeting where it was damaged/wrecked.
