Hmm, so this 67 Commando motor on the stand with the small register is a one off?? How about all of the 66 Commando motors I have here?? Yep, all small register!!!
64 - 66 are like that 67 was the change and the first year of the 318 and from 67 - 69 the two are identical except bore size the was no more commandos steel cranks and solid cams. yes if you swap a 318 into an 64-66 you need a later trans also if you swap in a early 273 onto a later trans you need custom converter or later crank. Or go standard.
