I got mine from
www.momarefi.com. I chose this set up because of the better construction. It's all billit, and not cast. Cast parts can change size if the get too hot. They don't use seals on the shafts, either. Some kind of NASA product keeps them sealed and lasts forever.
I used a Blue Oval Weber manifold, and had to make the mod for the vacuum manifold. But the manifold used by
www.verycoolparts.com has the vacuum manifold cast in to it. If I were to do it again, that's what I would use.
The computer you choose will make all the differance in ease of use. I bought my system about 4 years ago, and used a Haltech fuel only computer. It can operate on narrow band closed loop for general cruising. But it's a little difficult to tune, and really needs dyno time to get it right. Newer systems have a wide band WEGO sensor, and are self tuning.
Also, pay carefull attention to smog requirements in your area. When I got mine smogged, the specs I had to meet depended on the year the engine represented. I showed them a picture of a '65 with webers, and that's what I got. I had to meet '65 standards. Some areas of the country are not so relaxed.
