merc 114 280c diff ratio change out

hi all..though that i would consult the wisdom of the many who have gone there before me..i am currently in the process of changing out the solex 4a1 carburetor to a 4360 holley and seriously considering a differential swap out..i am running a 3,92 which i feel is too high to a 3.07 which i already have..apart from the speed reading being wrong(maybe change drive in the tranny to suit odometer)...has any one done a similar change out and what are your experiences with that..good or bad..fuel consumption is one factor to consider..we are paying NOK 14.90 kroner(US.$1,93) which is norwegian kroner for one liter or 3.8 liters is roughly one US gallon $7,33..hope my calculations are correct..any way not so far from it..VERY EXPENSIVE MOTORING HERE..

The diffs should swap out. You'll have slower acceleration but the rpm's will drop at highway speed. I've not done it but I don't expect it to be a problem. People are swapping out even taller gears in diesels without complaints.

With best regards
