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.
