3.55, 3.73 or 4.10

Put me down fo 3.73's...I had them put in even before I did the performance rebuild on my motor (i.e. the motor was stock other than some bolt ons) and DAMN did they make a difference. I love them, and wouldn't give them up for anything. When I picked my car up from the shop, the guy said, "Man, just try and keep that damn thing between the ditches." hehehe...he took it for a test drive to make sure everything was all good and nailed it...and got all squirrely (sp) so, anyways, I would strongly recommend the 3.73's. I have a buddy who has almost the same motor as me (nicks 5.0) and he has 3.55's....then he drove my car, and fell in love with the 3.73's....just somethin' to thinka bout. also, rpm's going down the interstate are going to be a negligable difference, like 500 or so. i run about 3,000k @ 80mph. It also makes for EASY passing of any cars on the road!!
