78 suburban 4x4, need economy ideas

would like to get better gas mileage, was wondering what trany i could upgrade to. maybe a t400, is there a trany that has 5 speeds. i do still tow a trailer with it.

also thinking about fuel injection instead of my 1406.

what about ram air instead of a centered air filter.

any help would be appreciated. thank you.
