360 magnum

I also used the magnum exhaust manifolds, pass side was no problem at all. The driver's side was close, but helped by shaving the engine side about .040" at an angle and slightly massaging the area closest to the steering gearbox and then the same area of the gear box itself. I then cut up the factory Y-pipe and made 2 turn downs to supply dual exhaust, but not convinced I am happy and may end using a set of headers that came on the car.
