I only have one data point for you, but the TTis I installed on my Road Runner with a Hemi fit perfectly. No power steering, but it is a 4 speed car. Only issue I had was having to use aftermarket oil dipstick tube. If I had been smart, I would have bent up a new tube and used stock dipstick. I am also using a mini starter.
