Best rear end gear ratio for Ford AOD?

My stock 8.8 inch rear end has met it's maker, after 53 years, so I'm up-grading to a 9 inch. I'm running a 302 with an AOD transmission. I believe my stock gears were 4.11:1 -- nice off the line, but not too practical for the freeway. Although with the OD I was able to cruise at freeway speeds.
I was wondering if anyone knows/has an opinion about which gears would work best with an AOD. This is a purely street car, but I still would like decent power off the line -- you know, just in case

PS
It'll be a posi/track lock rear either way.
Thanks in advance.

use the calculator to decide how you drive/ tire size/ where the powerband is/ desired cruising rpm.

 

Depends on your engine setup and the height of your tires. With a 26"ish tire height...3.70ish gears are the best IMO. Will turn about 2300-2400 at 75 mph in 4th with and AOD (O/D = 0.68 btw).

 

Thanks for the link, 53Sled. That calculator is pretty usefull.

Yeah, 3.70 gears seem to be pretty popular. A friend of mine is going to build it for me, but the gear sets he has are either 3.89 or 3.50. One's seems too tall and the other too short.

 

I'd go with the 3.50 gears. 3.89 would be ok if the rear tires are REAL tall, though.

 

My tires are I think 27 inches tall or so. They're radial wide whites from Diamondback Classics.

 

if they were 29 or so I'd go with the steep gears, for 27s I'd stick to 3.50s.
