I have an auto and I like my 3.73's because we get our car out on the highway quite a bit. If you just looking for great off the line performance with minimal highway use then 4.10's are the the ticket, if not then get 3.73's.

Red, whats your RPM at highway cruising speed? Im still trying to decide which to go with. My first thought was 4.10s but during the summer I make occasional hour plus drives up north to go the beach and the Fun Ford Weekend at Epping, NH. Kinda leaning toward 3.73s now.

Depends on what your goal is going to be. If you're only doing simple bolt-ons with stock HCI (or ported stock heads/intake like me), the 3.73 is the best choice. If you're going for an aftermarket HCI, the powerband will be shifted to higher rpm so the 4.10 would be a better choice along with a higher rpm stall torque converter.

At 65 mph I am turning 2300 rpm's, I like the 3.73's because as previously mentioned my car see's highway time.

I would go 4:10's with an automatic, 3.73's manual for a mostly bolt-on stang. I think you will be disapointed if you go with the 3.73's. If you don't do a lot of highway driving, I don't think your gas milleage will be that much worse with the 4:10's. Maybe 1-2mpg difference at the most.

auto = 4.10
5speed = 3.73

I always get pulled in on these gear threads
and
I have seen some changes over the years

Just a couple of years ago ... the big debate was over 355's or 373's

Hey ... Peeps are learning and old myths are slowly dying

Me ... I would have been more happy with 410's
but
Consider these things about my application

My car is a weekend toy only
The power band has been extended
It has a stick trans

Something you might want to try is driving on the highway with the OD turned off. It tachs way above what it would with 4.10's. (About 400-500 or so rpm's more.) I have found that even with that many rpms, it isn't objectionable as far as noise levels and stuff are concerned. I think it would be like a 4.56 gear...I think.

Just a thought.

My ratio of choice :Word:

With my top loader 4 speed
and
9" rear end

When I was a kid

With only a 1 to 1 final ratio and blown out Glass Packs .....
Two things always happened

1) It screamed goin down the highway
2) It attracted every Cop in town

Sometimes ... You guys send me down memory lane
