Interesting story, I've never heard about any of these 65 Hemi Plymouths or 65 Hemi Dodges running these type of road courses before, but do recall seeing some old photo's of a 65 Hemi Dodge running some rally road courses. It must have something to do with Nascar outlawing the Hemi motor back in 65 and they needed a different outlet to race, remember when Richard Petty switched to drag racing and raced a Petty Blue Barracuda.
