6x6 cmp gun tractor

[David_Hayward (RIP)]

The suggestion for the installation of the Chrysler straight-eight probabl;y arose out of the original clamour for a 6-wheeler better than the F60H. As mentioned before the Lincoln Zephyr V-12 was proposed by Ford of Canada as well as a "F60X". The V-12 was of course produced in rjd form but the fuel consumption would surely have been horrendous, and 12 plugs meant more leads, plus, plug caps, etc. The engine settled on was the GMC 270 although I wonder why they did not go for the 348 which Walkerville wassembled in 1940-41? My guess is that the 270 was becoming standardised at the time for military GMCs, although arguably lacked the power required and this fact was known at the time. The DND papers show that GMC, Mack, White and Dodge 6-wheeler trucks were considered before the C60X became a fait accomplii.
