the 1991 3000gt are dohc. it comes stock with 222hp. they also made sohc but that wasn't until later generations of the 3000gt's. The 1991 dodge stealths came in sohc, compared to the 91 3000gt's dohc. either way, with minor adjustments, it will fit from sohc to dohc.

Loosen the alternator tensioner bolt. The alternator belt will become loose. Remove the alternator belt. Put the new alternator belt on and reverse the process.
