Thanks for the link Jim, whilst doing penance and recovering from the severe beating, I followed up on the article, to refresh the dodgy memory and found this:

Looks like a longer piece that your article may have been taken from.
It had an interesting point that I really did not know:
"It should also be remembered that while running the H16 the team worked on the BRM V8, Westlake V12, Matra V12 and their own BRM V12 - all race winners at one time or another."
All really good engines!
Perhaps they should have just gone with a 3 liter version of their original V8.
