3.55 is my go to gear.
However. This is a trick question. I run a 340 stroked to 418 with w5 heads and 28" tires.
I had 3.55s for awhile till i changed transmissions to passon performances Hemi Overdrive
Hemi Overdrive
I installed 4.30s, but now contemplating 3.55s again as all i ever do is street driving with kids in tow.
Mind you for the record. I do plan to pull the 418 and trans out and put it into the 96 dakota. I want to stroke the 400 to 512 and mate it to a t56 trans.
