exactly.. "stock" the way tech works for stuff like these, is that they will do a general safety tech, weigh it and usually give the car a basic visual inspection, if he's in the top three the officials will decide what point of the car they want to inspect, which is usually the carbs, tires, weight or rear end.
Personally, if you can get away with it, is to run a modified vg30e with a carb. the only problem, is that you need the factory ECU to control the spark.
