The major difference between the 727 and the 904 is the length... with the exception of the 727s built for motorhomes. I'm no expert on this, but I'd say that a 318 in an A-body or an F- body used the 904, in B-body, C-body and E-body cars they were 727s because those bodies normally had the longer transmission. This is the case with the length of manual transmissions in my experience, A833s, A230s, A903s. I don't believe I have ever seen an A745 in a shorter length so they may never have been fitted to A-body cars. On saying that, however, 727s can be fitted to A-bodies, as can longer manual transmissions. They will require a shorter driveshaft, of course, and the right yoke for the 727. All manual transmissions in B- and C-body length have the same yoke as the 727 while the A- and F- body transmissions can have either. In Australia, when there were shortages of the Borg-Warner 35 transmissions usually used in Valiants with Hemi 6s (strikes and supply problems were huge in the early seventies), and when someone specced a car to have a 'tow kit' with a Hemi 6, 727s were fitted to these cars. I'm not sure why they weren't fitted with 904s. -- -- Please address private mail -- mail of interest to only one person -- directly to that person.
