The Edelbrock 1910's are the same exact castings as their 1903, 1904 and 1905's. They were patterned from the early 1990 Chevy Truck units.
On the 1910 they used a shorter stop for the secondary air flap shaft so it opens further, and added "tabs" to the air flaps.
It has a much richer calibration for idle as well, otherwise it's the same as any other later model Chevy truck carb......Cliff
