which cam should i get?

What year is your motor?
If it's a 94 then you have hydraulic roller lifters.
Ford switched from flat tappet lifters sometime in the 80's if I'm not mistaken.

85 was the first year for roller lifters in the Mustang

+1 on the custom cam. That will get you the most out of what you have.

OP - Has any decision been made?
