Carb options for a 360, opinions?

I would run the Carter, I think you will be very happy with it.
But in my opinion, the perfect carb for your particular car/motor would be the Edelbrock 650 Thunder Series.
For the street, it just flat out works on a small block.
Dont buy new, suckers are expensive. You can find them in like new condition for much less.
And are you ready for this ? You wont be fussing with it on a weekly basis like a british motorcycle. :)
