3.27 8.8 in Barracuda, 2.80 9.25 ford in 69 AMX with 5 spd richmond, 3.4something in 68 chevelle, coronet is 3.55
 
I had 3.23's with a 340 4-speed and 26" tires and it got 15 mpg at 70 mph on the freeway, which is where I drive it most of the time. I pulled them and put in a poor-man's overdrive - 2.76's with 28" tires and now it gets 19-20 mpg. Big improvement and I can actually talk to my family too. Only problem is starting off the line is pathetic and hard on the clutch. I think 2.94's are probably best for mostly freeway driving with a 4-speed.

I am running 3.23's in my B-body with a GM auto-overdrive and it is heavenly. :)
 
calculated 350s most the time or switch to 430s and here we go! four speed trans.
 
I have 3:23's with a SG 28" tall tire and 511BB. I have another 489 case that Im thinking of building up with a set of 3:73's
 
7 1/4 sure grip 2.94's currently, 13 inch pizza cutters. Ill see if i like the 2.94's in my 8.25 sure grip to be swapped in with 225/60/15's...if not, 3.23 swap. good enough gear to keep the rpms in a manageable range cruizing (i have a lockup 904) but still "tall" enough to get crazy with.

In my '64 I run 3.27's in the 8.8. Keeps my RPM's low for long distance freeway use.
 
i run 4.56 gear in the dart and 4.30 gear in the avenger
 
8 3/4 with 3.55 detroit true-tracs behind a 360/320HP crate and 727 with p295/50/15's 27" tires. Soooo much fun.
 
hi, 72 340 duster with 4 speed trans, 9x 30 slicks, 5.57 gears, 7300 in traps.
just food for thought
 
2.90 in an 8.25 SG. It is great for cruising, which is what I built the car for.
