EA diff?

gday,

im just wondering wat the final drive ratio is in a stock EA falcon S MPFI?
cant seem to find the info anywhere else,
and why is it that VL commodores get a 3.9 final drive ratio? why ddint falcons get anything like that? is that because of gearing ratios and different power or wat?

cheers, alex

Re: EA diff?

Re: EA diff?

In practice they seem to vary wildly. 3.23 is rare, most of the serII mpfi manuals I see have 3.08 or 2.92.
I've seen cfi manuals with 2.77, 2.92. and 3.08.
Our serI auto CFI got a 3.08 diff.


I think it was all optioning really, most of these cars they never changed the oil let alone the diff You will have to crawl under it and look.

i was just going by the ford brocshure and spec sheets for the EA

ive seen a fair few 3.23 diffs in wreckers but mostly under Ghias have also seen EB Fairmonts with 3.08 but never seen a series 1 EA with anything but a 2.77 or 2.92.
