After reserching cam lift and duration numbers it seems that the best combination would be to have the gts intach cam with the gt exhaust cam. The one area that I am not sure of is overlap and centerline of these cams. I am running a stage 3 tim murphy seup in my 89 gt. Any information would be apreciated. Thanks

 

why do you want the GTS intake cam? the GT gives more lift i think, and from what i recall i thought that forced induction wanted longer duration for the exhaust?

 

I think low overlap is the key spec.
