Derricks old notch??? sounds like the same specs. 5.0 mag did a bolt turbo from one of the well know mustang turbo manufacturers and the car made something like 400+ just with the turbo kit. Car was stock. I think the 400+ dyno pull was on 11 or 12 psi. I wanna say the kit focuses on 7 psi so u should be good. Derrick would be the man to ask/PM
