I've seen the manifold on the Century, but I don't remember it being particularly strange--probably because it's a 312 and therefore kind of Greek to me anyhow.
Next time I'm by there I'll have to get pictures of it. It's got the original gauges in it, which of course people try to replicate or emulate now, but these are the real deal from the era. I love the water, and I love boating... and I'm a total sucker for the sound of a V8 with the pipes half underwater. But even though it's in reasonably good shape, I just can't see myself buying something of such limited use to myself. Plus, the entry fee is $6,500, which I could see paying for a fully-operational, ready-to-run boat, but for a project? :dgt:
