When it comes to Carters, I'm in the dark. Well, not so much anymore after the above recommendations. I may end up with 2 NOS Rochester auto-chokes on it, otherwise I'll go the W-1 route as mentioned.

But, since I pretty much matched the Tattersfield to the Edelbrock, now I'm wondering if the Edelbrock is a 216 model? Only thing is, the carbs on the Edelbrock are 235 pattern. The exhaust manifold patterns are the same on each. Is there a "remote" chance the Tattersfield actually is a 235 version with early carb flanges?

I'll get some photos tonight to post.
