There is a red e12 floating around amongst the regular posters on that board that had a 3.5L with triple sidedraft webers. There are kits available, and when I was looking there were a few people who had some experience and some systems available. You will get mixed reviews, and the fuel consumption seems to be an issue, but it makes for a very impressive engine compartment. I have some pics somewhere, and there may be some on firstfives
