Due to it being introduced in the late 70's/early 80's, some people think it's an emissions manifold, which it is not. It's not a race manifold, like a Torker, etc, would be, but if you have a relatively stock to mild 273/318, it will work fine. An LD4B might be the best manifold for your application, but if you can't find one, I like the SP2P. Sometimes less is more, y'know?
