Edelbrock models 1405 versus 1406 carburetors

YES!!!
No more bog when flooring!!
What solved my bog was to open up the blocked heat crossover, then I had to re-tune the jets and rods wich result that I could jet a little bit leaner than with blocked crossover.
Smaller nozzle (from 43 to 31) and outer pump hole, otherwise I got the opposit rich condition when acceleration.
Perfect! No more lean out when flooring, perfect AFR all over.
I did suspect that the crossover should affect the AirFuelRatio but not that much.
