I've got a 1962 Dodge pickup with a 225.I put the 4-spd OD trans and 3.50 rear axle from a 1977 model in it and went from 11,to 16 mpg.I did the electric cooling fan and steel radial tires and that got me to 18 mpg.A home-built streamlined nose,front wheel gap fillers,full rear skirts and aero-shell pushed it to 21.5 mpg with a very weak engine.------------ I know of Dodge vans with 318s that got 22 mpg.They might have been stick shift,don't remember.-------------- I put a 18-inch boattail extension on my VW van and picked up 4 mpg.NASA has done this also.If you can deal with the length,it's a no-brainer.A very detailed bellypan should help.With the automatic,you would need to be cautious with a grille block,as you could cook your tranny fluid.
