Easy swap and maybe 11 mpg.
350 TBI or Vortec = about 18 mpg, lots cheaper and 100x the parts available. My personal experience with any of the AMC V8's is you are very lucky to get 15 mpg no matter what you do to them and for dollars spent, a Chevy will tear you a new behind. More work and money to install a sbc but a better finished product in every way.
