exhaust woes ......1973 340 into a 1965 barracuda

I had 68 good manifolds on my manual steering 65 and didn't have a fitment issue. I bought it like this so maybe the manifold was ground on in one close area but I don't remember. Power steering no way. Did you try magnum logs? They dump high away from steering box. May have to grind a tad for the steering shaft? You can raise or lower the motor in relation to the steering box with thick 65 or thin 66 motor mount isolators.
