Stalling during stopping after engine is warm

[FWB]

Every set of dual Holleys I've seen has the primaries at the back, simply because the distributor is at the front, and you can't fit a Holley facing forward.

I agree with GAZ on this, the factory ford setup appears to be backwards.
in retrospect i think all the others are backwards,

but , the tuning won't help the float itself is a contributing factor, the lemans bowls, side pivot, offers relief of this condition but won't fit the 2x 4 setup.
the hose pictured above connecting the two vent tubes is a help.
the vent whistles offered in the holley kits don't fit the factory style metering blocks.
