Update, just put my first 150 miles on mine...super smooth shifts,
quiet,put her in 5th rolling up I-5 and it was awesome at 70MPH.
Motor just loafs along.
When I broke in this motor with the 4 speed and 4.10s it got 6 MPG.
With the 855 and 3.54's I got 10.5 to 12.5 MPG,
may not sound like much, but hey a 572 Hemi with a roller cam and 2 4 barrels running all the time... to me is pretty good! Means that theoretically
I could get 180 miles + on a tankful!
More later,
case
