In my 55 there is a 350 followed by a 700R4 tranny,dumping into the original 3:90 rearend.20 MPG all day long.Not too bad on economy as far as I am concerned.To my way of thinking gearing means more than engine choice for economy.The 700R4 tranny is an overdrive unit which feeds a relativly high rearend and does a nice job.Plus that 700R4 has a really mean first gear,if you wanna blow someones doors off.
