Intake manifold options for a Magnum 5.9/360

We ran the dual pattern Profesional Products crosswind on a 360 LA in his 73 Duster and had no problem with port alignment on our 308 heads. Car ran 108 mph at 12.4s. Still have it but we're too far away to save you any money.

I used one on my Frankenteen build years ago. Magnum heads on an LA 318 short block. I never got to fire that engine, unfortunately, as I had to end up selling it, but the intake fit very well. Some do and some don't so it's something you have to play by ear. Same as the Edelbrocks now though.
