I would caution folks about what is the best ratio.

Depends on the terrain you live in and what you are going to do with your FC.

Flat landers can get away with a 3:27 ratio and be happy.
If you live where there are hills & mountains ( like WV, Western MD,
Southwestern to central PA, etc) then a 3:55 is the better choice.

I had a 3:55 in FC and yes sometimes I wished for a 3:27 or a 5th gear (OD) to
slow the engine down, but the rpms never hurt the engine.
AND remember that folks never worried about such stuff when the cars were new.
I ran the he_ _ out of my new CORSA (3:55 posi) to Albuquerque and back from
Pittsburgh and it never minded.  Still running that same engine today and it
is fine.  The body has changed, but not the engine.

If you put the engine together right what's the worry???
