i just bought a 75 dart swinger with a 225 slant 6 and a single barrel carb. i am planning to swap out the single for a 2 barrel. where can i find an intake manifold for such an application?

hey bro, check out the 'engine' forum here, do a search for "super six, supersix", you can get a supersix (2 bbl) intake/carb from a late 70's Aspen or a Volare, trucks? , do a search and you'll find the info
