When I had my 65 327/365 it came with 4:11 but a friend of mine with the same engine had 3:70.... Its whatever the buyer checked off at the time of purchase... but then too, someone could also have changed out the rear end... so who knows.... :confused:

Most L76's came with 3.70's
Then the 4.11, and 3.55's.
With the 3.08, 3.36 and 4.56 being a seldom
ordered option with this engine.

Do you just want to know which ratio you have? Easy to do. Put a chalk mark on your driveline (rear wheels off the ground) then turn your tire one complete revolution. Count how many times your driveline turns. Get it? :cool: :cheers:

Here's a nice ratio calculator to use.

Give it a try. It works pretty well.

As stated the standard ratio was 3.70, but there were five optional postraction ratios from 3.08 to 4.56. Give me your tach reading at exactly 60 MPH and I'll tell you the ratio, assuming that you have the correct speedo driven gear for the installed axle ratio.
