Title: EDELBROCK 1910 QJET
Post by: qjetsrule on March 25, 2019, 02:08:19 AM

The Edelbrock 1910 Q-Jet is rated at 850cfm, what's the difference between it and a large primary Rochester Q-Jet? Thanks

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

Are  the secondary air flap "TABS" better than the normal flat tabs? Would this only benefit Chevy engines or were the tabs designed for all engines? Thanks

The tabs do pretty much nothing from what I can tell.......Cliff
