Not great quality on this copy of the video but still interesting. http://www.youtube.com/watch?v=09_0Datx2hg
I didn't know the 400 was standard on the LeMans wagon back then. Beats the 301 that showed up a few years later all to pieces!
That must have changed from 73, in 1973 the 350 2bbl was standard on a Lemans Safari, with 350 4bbl, 400 2bbl, 400 4bbl, and 455 4bbl as options.
