yeah the demon setup is loosely based on the old autolite inline carb but BG isn't making a ford manifold yet, supposedly they are working on one for the new Ford racing Boss 302 crate engines though
nascar didn't want anyone but GM to win ever, even now it's the same thing. if anyone from the other camps comes up with some new ideas nascar always outlaws them eventually, that's why i quit watching it. they outlawed the 427 cammer before it even completed 2 races, they outlawed the boss 9 shortly after it showed up on the track, they pretty much outlawed the aero cars; plymouth superbird, dodge daytona, ford torino talladega and cyclone spoiler II or limited them with small displacement motors (305 ci) after the 70 season and the restrictor plates were originally developed for the hemi to slow it down too. i can't think of one single instance where nascar ever did anything like that to GM.
