According to a 70 Formula 400 Automatic Non-AC Buildsheet, 3.07 was standard issue with 400 Auto Non-AC.
But this Buildsheet is NOT a RamAir car, your example is RA.
Thinking the RA Engine put an Automatic Formula to either 3.31 or 3.55 as standard ....
i Don't Know which

Standard ratios for W66 (if I have deciphered it correctly):

L78 & M13 = 3.55
L78 & M20 = 3.55
L78 & M21 = 3.73
L78 & M40 = 3.07*

L78 & M13 & perf axle = n/a
L78 & M20 & perf axle = 3.73
L78 & M40 & perf axle = 3.31*

L78 & M13 & A/C = 3.31
L78 & M20 & A/C = 3.31
L78 & M21 & A/C = n/a
L78 & M40 & A/C = 3.07*

L74 & M13 = 3.55
L74 & M20 = 3.55
L74 & M21 = 3.73
L74 & M40 = 3.55

L74 & M13 & perf axle = n/a
L74 & M20 & perf axle = 3.73
L74 & M40 & perf axle = 3.73

L74 & M13 & A/C = 3.31
L74 & M20 & A/C = 3.31
L74 & M21 & A/C = n/a
L74 & M40 & A/C = 3.31

the assembly manual is a bit confusing regaurding L78/M40 with or without A/C... there seems to be some doubling up, so these are my assertion.
