Ford 534 C.I. Gas Bird

[George Burke]

My new to me 1977 FC31 gas powered Bird needs a little help. Would love
to hear from anyone who has ,or now owns a gas powered Bluebird that
came with a Ford 534 C.I. engine. Issues are what did you do to improve
mpg.Did you ever have the rear gear ratio changed? If you had a 100
gallon tank, did you run out of gas at 90 gal., (in other words, thats
all it would take when we ran out!)Any help,i.e (if you do your own
mechanic work, or where if you had work done by someone else), would be
appreciated. George Burke 1977 FC31SB Charlotte
