You could say that the air meter works on vacuum (differential pressure). Flow through the air meter body causes the air plate to rise which in turn raises the plunger in the fuel distributor. The plunger position w/in the fuel distributor and the fuel control pressure determines how much fuel is injected into the engine.
Reasons why folks have used conservative cams on a CIS engine:
-piston/valve clearance
-intake pulses (reversion) that will result in an oscillating air plate...(see above interaction as it relates to fuel).
I love to see folks wanting to experiment, but I think you should research CIS cam timing advance, and 964 camshaft installation first.
