I got 4:10s on my Stang back when it had the stock motor in it. Didnt hurt daily driving all that much. Actually helped around town, but once you get out in the country and can let your cars legs stretch a little, then you might notice a drop in your gas mileage of course. Its not all that bad. And made it fun as hell to drive...wow.
The diffrence from 3:90's to 4:10's is negligable rpm wise at 60 MPH, and the gas mileage diffrence would be that also.
I drive my stang everyday to and from work, about 40 miles round trip. As long as I short shift the hell out of it I get decent gas mileage.
The headers I got are full length. Cant remember what company I got them from (Off of E-bay). There pretty nice, primaries and collectors are two large for a stock car (They might make smaller ones), but I was able to attach the Headers, Tranny to the engine on the stand and drop the whole shabang between the fenders with no problem..took like 3 minutes to get it in. The headers also give you clearance to drop down the tranny for service.
There pretty awesome. I'll get the name of the company and pass it on.
