I currently am in the process of swappin out the 351w in my 86 bronco for a 460 but I am undecided on the way to go in the area of fuel delivery. I am concidering a holley pro jection system or a truck avenger carb but I have not heard any ones experiences with the carb. I would like to here from any one who knows how the carb performs in off road situtaions. thanks
