C60X Machinery bodies..Manuals of equipment? surviving "complete" examples?

[Alex van de Wetering]

Bob, Grant, thanks for your efforts and comments. I have seen Andre's name come by on the forum quite a few times and sometimes one forgets that not all CMP-nutters are on the World Wide web. If you guys do go and visit Andre in due course, than I would love to hear more about his truck; Bob's description has made me very curious.

Alex.

Hi Alex,

How far is your project ?

Cheers,

Hi Danny,

Regarding the scale model..I am currently working on the GM270, bellhousing and gearbox, as well as the axles. Most of the rough cab parts are done and chassis as well. The basic structure of the rear body is there, but nothing done on the interior yet and lots of detail still to be done on chassis and cab.

By the way.....I have talked to a few (former) C60X owners who ensured me the engine was longer...which resulted in the grille needing a spacer....so, I was surprised to find the 270 block to be the same lenght as a 216....if I measured correctly. Also, I understand the C60X uses the stock Chev gearbox.....so, is the bellhousing this much longer leading to the engine being more forward ? and new mounts being used....or is it a bigger radiator and or different fan that leads to a lack of space up front ?

I just came across this older thread so I thought I would post some photos that I have. They're not great photos but I think at the time it was the best I could do.

Whatever engines you measured Alex your conclusion is incorrect. The 270 engine block is definitely longer than the 216 by around an inch and a half. The bell housings are dimensionally similar between Chev and GMC. I am not truly familiar with the C60X but am fairly sure the gearbox was heavier than that used in the rest of the CMP Chev family though still a four speed with 1:1 in top gear. (Not overdrive)
I've switched engines 216>270 and 270>216/235 a number of times and unless the CMP used a different length 216 to everything else cannot explain your findings.

Ian,

That's Andre's truck, right? Lovely! Possibly the only (?) retaining orginal tools in the back.

Whatever engines you measured Alex your conclusion is incorrect.

David, you are right. My earlier comments on the block being the same length is indeed incorrect. I found out recently after I rechecked my measurements when the discussion on possible engine swaps for a chev 216 came up in another thread.
So, the 270 block is indeed longer than the 216 block.

If the markings are correct on the door of the above photo's truck, it leads to a few interesting anomolies. The upper number of 43-30207 would appear to be a CAR (Later called CFR) number using the 43 build date. However the 30207 number falls into the numbering block for the Jeeps. I have never seen a CFR based on a WW2 date, nor a CFR of a non-1/4 ton vehicle in that block back then.

I would have to check on the 22-211 number. Vehicles other than motorcycles, were to be numbered starting at 50-001. Motorcycles would be 2-001. I'm not sure if the RCAF used a different system or numbering block.
