Went from 3.73s to 4.10s behind my T5. I wouldn't think twice about doing it again...cheap HP and no real change in MPG.:D

I'm keeping the 3.55's. They seem to be a great all around gear,especially here in town doing mostly local driving.

3.73s+2800 stall=traction issues. Ask me how I know. 4.10s would be fun but I'd have more trouble getting the car moving from a stop;)

I have absoulutly no problem with that set up ,I also have a reverse manual valve body in the trans in my TBird .
My 73 Montego has 430's in a detroit locker with a 3200 stall convertor in a c-6 , also with no problems .

how do you figure? 4.10's increase acceleration

i'm running 4.10's with an eaton locker, C6 and 3500 stall in the capri.. been on the road for about a week now, driving everyday and i couldn't ask for a better combo with the 408

anything lower than 4.10's are highway gears in my book :p

The 3.73's seem to be nice combo gears. Interstate travel at 3200-3400 is movin out, but it won't trap the rpm high enough for the aod at the track. I dont think I'll miss the lower top speed and higher rpm on the interstate much. 4.10's ftw.
