I'd have thought that they may have changed to the Webers later , they kept changing everything trying to get perfection. I thought I saw the FE with dual four Holleys. I've seen so many videos this last week, it might have been a seen from a video. In that time frame it would have been dual fours or Webbers to get 1200 CFM or more. Now a single large four could do it. I didn't see any intake filters on any race engines. Nascar uses filters now and are only going 500 miles in about four hours around the same loop not 24 hours out in the country side.
