Throttle cable

Going from a slant 6 to 360 la in a 75 dart i noticed my throttle is extremely too long. Anyone done this conversion used the factory cable or im i gonna have to replace it?

Hey Kevin, not to change the subject here but is that magnum exhaust manifolds you have installed there?
I remember us talking about that in a different thread. So how do they actually fit and will the exhaust pipes fit in ok?
