Basically the o old 855 or NTC were the mechanical motors, now the N-14's are the pretty much the same block,heads and everything except the addition of electronic injector units and electronic controlled injection, they are still 855 cu in. Now on the 93 you are looking at it could be an N-14 and still not have a jake or cruise, just all depends how it was speced, or it could still be an NTC series, but if you know for sure it is an N-14 then it just could be speced that way, but i will almost guarantee you it has cruise just not the switch's on the dash as that is all controlled electronically, but the jakes are a mechanical option.
