Steve, I do have issues with the #1407 Carb. Mostly the major bog on acceleration even with a mild roll on the throttle. I too feel the lean hesitation on light acceleration from idle but it doesn't bother me as much as the bog on any brisk application of the throttle. I've contacted Pep Boy's about an exchange to a different Eddy # carb with no response.

What would be a better # for a Stock '68 383 auto?
Thanks again for your Eye Opening and Informative Post!
