I have a 85 mustang2 circle track car with a 2.3l N/A and was wondering if mustangs ever came with rollercams in their carburated years if not what year did they become avaiable i only ask because im looking for more HP and my rule book is a little tricky to work around
any help on the matter would be great

The first roller cammed 2.3 Mustang was the '91 model year. It was also the first year the dual plug / DIS setup appeared in the Mustang. Both the cam and the head had been in Rangers since '89.
