How much do the S Tracs weigh?
A lot of people don't know how much more power a Ford type 9 inch rear end takes to make it rotate compared to any other popular rear end made in American productions cars
Every race ready Ford type rear end that I've seen or heard from racers who priced them against a Dana 60 cost any where from $500 to $1500 depending on which race parts where used on the 9 inch rear end, the better stronger parts cost more money
