I had a check in my CanAm files and the 'Ultimate' engines fitted to the factory McLarens were Reynolds Aluminum cast Chevrolet 9.25 Litres monsters, in an attempt to combat Penske's 'Panzers'.
Chevrolet ["We aren't in Motor Racing" - 1967] seem to have 'loaned' Reynolds the patterns for the 427 block which was cast in Aluminium and initially became 'standard' in Jim Hall's Chaparrels and the factory McLarens, and a couple or seasons later they were sold to several top rank teams.
Ford's '429er' appeared a several times under the Agapiou Brothers care, this engine was actually a 494 and impressed Mario Andretti in a big way!
Parnelli Jones and Mario Andretti both drove Lolas with Ford's DOHC 'Indy' power behind them, and Mario had a Turbo Chevy to call on in 1973, but by then Porsche had claimed the top slot.
I can find
one [
that's 1] Chrysler Hemi powered CanAm effort, an epic fail owned by John Mecom and driven by AJ Foyt, the oddly named 'Hussein', complete with giant pancake Chrome plated air cleaner sitting on top of the engine cover.
She vanished without a trace, so I'm told.
The CanAm wasn't a great 'racing series' as the Bruce and Denny Show tended to dominate, followed by Penske's Porsche 917 turbos that effectively killed the series off, but there were some bloody great cars up to the point when Jim Hall found his exotic Chaparrel 2J 'Sucker' banned by the SCCA, suddenly the series that had no regulations had the first of several and the interest level faded.
