first burnout with the 12v

i now get 22mpg and a huge smile on my face

what only 22mpg with a 1/2 ton chassis ...
nice job by the way!

my 96 12v gets 22+ mpg on the road. about 20 mpg in town
that's with 265-75r-17 wheels from a 2012 2500 CTD

22mpg was with the quad in the back and my very heavy foot

New to Forums. Have an 86 150, and a 92 250 with a IC 12 valve. Want to do this swap. What did you do, that you havent listed?
Fab up motor mounts?
Change out the fuel system? New tank?
As for your harness, did you just fully pull the body harness out, or use the Cummins one, and the gas job?
Can I get your facebook info to talk on there? Dont use forums.

Colt,
There are 50+ threads on the 1st gen forum that answer all questions.
Using this forum rather than Facebook for the needed info on this swap, would be much better info, in my option.
