Or keep it simple and drop in a Volvo transmission with overdrive. That in itself should get you about 4 MPG. The B18 and B20 will mate up to the same transmission. The Volvo 4 speed from those days was available with an overdrive. I think it was a simple boltin swap that needed only a switch for the overdrive solenoid and a shortened drive shaft.
If you do that, BEWARE. The spec for the overdrive transmission is (I think) 10W40 engine oil, while the spec for the 4 speed without overdrive is 80W90. If you put 80W90 in the overdrive transmission you will shear off a key inside the overdrive.
