If I go from fuel injection to carbs I take 4 points. If the venturis are different from "stock" I take 4 more points. How do you determine what is the stock venturi on a car which only came with fuel injection?
If I use Weber 46's and the venturi size is the same as used by a stock 906 do I avoid the 4 points for not-stock venturis?
If I use PMOs, what is the "stock" venturi size?
