I am looking at using either the MSD Atomic or Holley Sniper injection set up when I fit a reconditioned 308 to my van latter in the year. The engine engine would be stock or very close too and the main aim is to try and get some better mileage from the van as I am participating in a Round Australia touring road event in 2019. Have any forum members used these set ups and what has been there experience? I am dead keen to keep the engine bay looking standard so a VN style set up while logical is off the list!
