Maybe some of the mods used in the Feather Duster could be applied to your van. The 225 used in it had an aluminum intake and free-flowing exhaust manifold. With the overdrive manual trans it was claimed to get up to 36mpg. The Feather Duster used a 1-bbl carb but another version of the 225 (the Super Six) used a 2-bbl carb & the intake manifold from that might be what you are looking for.
There were some later 727 trannys that had lockup but I'm not sure if they were used in the 225's.
