70-72 Duster daily driver questions

Even properly tuned, we found the /6 to be a pig on gas...the 318 in my 2wd RAM gave me 30s... but engines are lie motorcycles...you buy a small cc and the first thing you are doing is upgrading..I'm for the VS.

Thanks for the input. I wonder what the justification was for the slant 6 then if it wasn't really any better than a 318 on gas.
