So I got all the issues worked out with the swap. Have about 1500 miles on it now. What a difference between an acert and this. My old bxs was a 475hp 1650tq and the 6nz is 550hp 1850tq. I run the same roads with it so comparison has been easy. Pulls hills much easier. Fuel mileage is a huge improvement. The truck runs a vacuum pump so it idles upto 6 hrs a day. The best I ever did with the bxs was 5.5mpg and that was with very little idle time. My average now is 6. I had 2 fillups at 6.2 one at 5.5(lots of idle time that day) and today I got 6.6.
Its been well worth the extra effort to do the swap
Engine swap???
