454C2500
Newbie
Hello folks - I am looking at a nice 454 2wd 3/4 ton 5 speed! I've always had Mopars but something about a TBI 454 with a 5 speed makes me intrigued. Can anyone shed light into whether the transmission is an NV4500 and if the rear is a full float 14 bolt? I looked under and it was a 14b but i didn't pop off the hubcaps to check for shafts . To that end I didn't look at the transmission case either . Its a model year 91 and I can't imagine an NV3500 would handle that motor but I just don't know GM all that well. Plans are to keep it stock except some slightly taller tires like maybe some 235/85/16....would those rub?
