With 4.10s truck went 11.93 at 112 mph. This is a 410 sm block with production heads, a 727 trans and weighs 4300#. Was worth almost 2 tenths and 2 mph.

Since you want to drive it Alot, Absolutely keep the 3.54 gears. I treid from 3.73 to 4.30 in my Duster with a pump gas 518 C.I. low deck stroker, it didn't make any noticeable differences at the track, other than spending a long time in high gear with the lower gears Mr.Cab Racing and winning with Mopars since 1964.
