Honestly...how good was the 318...mpg / durability / hp

I don't get the frame of mind of some folks. That somehow the 318 is a dead dog POS just because it was never offered in a real performance version. Kinda like people who piss all over slant sixes. Are those even real Mopar guys? Those two engines are purt near bullet proof and yet get the least respect of any other engines out there. ...and it's always by supposed "Mopar" guys. Chevy and Ford guys appreciate those engines. Just because something won't run nines, doesn't mean it's junk.
