Running 4:10 thoughts on a 5:13

I ran 5.13s on my warmed over 340. They worked fine on the street if you don't go over 45 mph. On the highway I believe at 55 I was running close to 4000 rpm. I wouldn't go over 4.56 for limited highway driving. With the 5.13s I was in third gear at about 100 yards out. You need lots of motor to run those gears.
