Actually you may want to thank Carter (no longer making carburetors) for designing it back in the 60's. I suppose you could thank Edelbrock for buying the design and keeping it in production.

It's a good carb that shines in simplicity. It is so simple that it's hard to screw up and easy to work on. They work well on stock to mild performance engines. The trade off though is that they just don't have the tuneability that newer design carbs have.
