Actually I did register, I just didn't have time at that moment. But thanks for the wonderful response. I feel really welcome at this site, which has so many people responding and communicating.
I have a topic I need some global information on. I'm looking at putting on the twin webers (32/36) for my '73 240. The kit they have is the K 688. It has a very long manifold that I've been told is hard to dial in, especially at altitude (6000 ft.) Apparently they no longer make the non CA SMOG approved shorter mainfolds. So what's the deal and what are the options?
