It all depends on what tranny you are going to use.If you are gonna use a 350 or 400 tranny it will be geared to low for good MPG.However that 4:11 would work out real nice behind a 700R4 OD tranny.The OD makes all the difference in the world for decent MPG.I am running a 700R4 with a stock 3:90 in my 55,it gets 20 MPG,and performs nicely with that wicked low gear.
