What v8 weber ir engines had air cleaners?
The Maserati Bora (kissin' cousin of the Pantera} was equipped with a 4.7 liter V8 making 310 DIN horsepower at 6000 rpm. That's more horsepower per liter than the 1970 or 1971 351C. It was fueled by four - two barrel Weber 42 DCNF/14 carbs. Notice the factory air cleaner assembly in the attached picture.

Look at the cam timing on 4 and 6 cylinder engines with ir induction. Which ones have overlap in cam timing? Which ones have 28 or more degrees of cam overlap?
28 degrees is a ridiculously small amount of overlap. Do you think any of those sports car engines had only 28 degrees of overlap? I can say with relative certainty they ALL had more than 28 degrees of overlap.

Intake tract reversion is caused by the late "seated closing" of the intake valves, not by overlap. It happens when piston motion overcomes air column inertia.
