Dual quad info

4spdragtop said

Hi all, I have an unmolested Offy DQ single plane and have been doing some reading about carbs and linkages. It's a ways before I will install, but recommendations for fuel supply lines, carbs(Eddy preferred) and linkage are appreciated.
DQ is going on a 70 340, slightly warmed up, 904 auto.
I'm not sure which linkage to look at? My 1st time with multi carbs.
Street car
Thanks
Steve

If new carbs are in order, check into the AVS II 500’s and the Edelbrock linkage Rusty posted up. The Edelbrock air cleaner may not fit since on the Edelbrock intakes, the carbs are super close to each other.

The progressive set up will have the secondary (front) carb come in at a reasonable area and have both carbs fully open by WOT. It’s actually a pretty good set up. You can out around town and drive the high way, to a degree, gear ratio and tire size will have a play in this. But…. If you have 2.94’s and down, you could get on down the road with just the primaries on the primary (rear) carb.
