Only if special ordered with extra HD cooling for the 3 row. The small V8 they went with what would do the job and nothing more. Stock rear end was probably a 2.41gear.Factory set-up was probably 3-row copper/brass. A fresh set-up would prob work fine or you could upgrade to a 4-row copper/brass which was more common on HD set-ups @ that time. 18-19" mechanical fan w/a clutch would have been the HD items as well.
