The stock fuel injection cam has a reasonable amount of lift but has very conservative numbers when it comes to valve timing, diuration, and overlap. basically an RV cam grind. The reason for that is to make it driveable on the street with more torque down low and a wider torque powerband at the expense of higher rpm horsepower. The stock fuel injection systems on 914s need a mild cam like this in order to meter the fuel correctly and to idle at anything under 1000 rpm. Carbs will work fine with this cam if they are dialed in correctly.
If you put too wild of a cam in a type 4 with stock D-jet it probably won't run worth a crap.

The only advantage of carbs is that they allow you to run a more agressive cam grind and get more top end power.

I can't give you exact lift, calve timing, duration etc numbers for the stock cam if that's what you are looking for.
