these kits include straight throttle linkage and triple-deuce kits include our exclusive progressive throttle linkage #1033 originally designed by Vic Edelbrock Sr. back in the late 1950's for small-block Chevy.

This is the standard twin progressive Weber DCOE system shown as shipped. It comes with a low-pressure fuel regulator, fittings, and base gasket.

This unit replaces any standard four barrel. The progressive linkage is important for economy, so it is standard on all the units.
